Foreword, General Information, and Terms
Section 1
Purpose
1.1
The information contained in this book is presented for use in planning electrical wiring and
apparatus installations intended for connection to the Entergy distribution power lines. Current
procedures, practices and requirements, adopted by the Entergy companies to assure
economical and satisfactory service to Customers, consistent with the most recent version of
the National Electrical Safety Code (NESC), are set forth and discussed herein. (Note: Any
statement concerning the National Electrical Code (NEC) refers to Customer owned facilities.)
Any mention of the NESC or the NEC indicates the basic provisions that are considered
necessary for safety. To the extent that Entergy's standards are more stringent than provisions
of the NESC or NEC, Entergy's standards must be satisfied. This book is limited to information
considered essential in planning installations which are adequate and satisfactory for the many
uses and conveniences of electric service. If the total service requested is over 200 Amps,
other than 120/240 volts single phase or requires more than one meter contact the Company.
Service Contracts, Terms and Conditions
1.2
The following documents are not included in the Service Standards:
1. Service Regulations (or Terms and Conditions) which prescribe the rules, obligations,
and liabilities of the Company in providing service and the Customer in receiving electric
service;
2. Rate Schedules (or tariffs) which set forth the price, periods of taking, and payment
terms for electric service;
3. Service Agreements wherein the Customer and the Company agree to specific
quantities and type of service.
The Company’s currently approved Service Regulations, Rate Schedules, Service Agreements,
and other forms are available by contacting the Company. The Customer should contact the
Company early in the design phase of a project for information concerning the terms and
conditions of service.

How to Interpret and Apply the Standards
1.4
When reading the standard, check out the key words (verbs):
Shall: A rule using the word “shall” is strictly enforced.
Should: A rule using “should” carries the idea that options exist, but that the rule contains the
best engineering expertise as written. This rule could be less strictly enforced than the “shall”
rule.
Recommend: A rule using “recommend” has several options, but the Company would like for
the customer to use the one given. “Recommend” is never used where safety is an issue.
Ahead of the meter: The Company side of the meter also called the supply or line side
Behind the meter: The Customer side of the meter also called demand side or load side

Electrical Terms Used in Service Standards
1.6
Ampere: The unit of measurement of the rate of flow of electricity. It is the unit of current
produced in a circuit by one volt acting through a resistance of one ohm.
Btu (British Thermal Unit): The quantity of heat required to raise the temperature of one
pound of water one degree Fahrenheit. Capacity of air conditioning, heating, or heat content of
fuel, etc. is measured in Btu. Btu/h is the rate of heat change - Btu per hour.
Current: The rate of flow of electricity usually measured in amperes. The Company supplies
alternating current (AC) and will not supply direct current (DC).
Energy: The total work done as distinguished from the rate of doing work (power), usually
measured in kilowatt-hours. Its amount depends upon the power and the time that the power is
taken. For instance, a power rate of one kilowatt maintained for one hour is one kilowatt-hour of
energy.
Hertz: Unit of frequency in Cycles per second For example, the Company furnishes 60 Hertz
alternating current.
Horsepower: A unit of power, equal to a rate of 33,000 foot pounds of work per minute.
Motors are normally rated in horsepower to indicate the mechanical power they are designed to
produce. One horsepower equals 746 watts. Motors require 746 watts input, plus losses, for
each horsepower output.
Kilovolt-ampere: (kVA) 1,000 volt amperes, the unit of apparent power, volts times amperes,
which is comprised of both real and reactive power.
Kilowatt: (kW) 1,000 watts.
13 of 1032018 Edition
Kilowatt-hour: (kWh) A quantity of electrical energy - equal to 1000 watts used continuously
for one hour, or 100 watts used continuously for ten hours, or some other equivalent.
Number of Phases: See "Phase".
Ohm: The unit of measurement of electrical resistance or impedance. It is that resistance
through which one volt will produce a current of one ampere.
Phase (or Number of Phases): Term which designates characteristics of alternating current.
It is a term used in the electric industry relating to the characteristics of the electrical service
available or supplied at a given location or required for the operation of a given electrical device.
Single phase is normally supplied for residences and small power customers and three phase is
supplied for larger power customers.
Power: The time rate of doing work, generating, transferring, or using electric energy, usually
expressed in kilowatts (kW).
Power Factor: The ratio of real power (kW) to apparent power (kVA) for any given load and
time. Normally, power factor is expressed as a ratio and stated as a percentage.
Reactive-kilovolt-amperes: (kVAR) (rkVA) (kilovar) The product of the applied voltage and the
magnetizing or charging current, divided by 1,000. Reactive-kilovolt-amperes do no work but
must be supplied to magnetic equipment, such as motors. Generators or capacitors supply it.
Sag (Voltage sag): A decrease in RMS voltage at the power frequency for duration of 0.5
cycles to 1 minute. Typical values are 0.1 to 0.9 per unit.
Volt / Voltage: A unit of electrical pressure or potential or electromotive force which if applied
to a load of one ohm resistance will cause a current of one ampere to flow. Primary distribution
and transmission voltages are usually designated in kilovolts (kV). One kilovolt is equal to 1,000
volts.
Watt: An electrical unit of power. Electrical appliances and lamps are rated in watts to indicate
their capacity or rate of using power for doing work. A 100 watt lamp used 10 hours will use one
kilowatt-hour (kWh) of energy (1,000 watt-hours). Likewise a household iron rated at 1,000
watts will use one kilowatt-hour in one hour.

Safety, Customer's Service Obligations and Protection
Section 2
Safety
2.1
Safety is paramount. If the Company believes, based upon observation, information or
experience that danger to the public or to an individual exists, work shall stop until such danger
is remedied.
Code Requirements
2.2
General
2.2.1
The data contained herein is intended to conform with and be supplementary to recognized
codes or rules and regulations of the authority having jurisdiction over the installation. In all
cases, those codes or rules and regulations shall govern, regardless of possible conflict in the
expressed or implied meaning of the contents of this book. The contents are intended to be
consistent with the principles of the NEC on the Customer's side of service and consistent with
the NESC on the Company side. Compliance with the requirements of the NEC will provide the
Customer with what is considered a standard for appropriate use of electricity. Any difference
from the NEC is intended to provide better service than required by the standards of the
Code.
Inspection and Approvals
2.2.2
The wiring, electrical equipment and appliances of the Customer should be installed in
accordance with the requirements of the latest NEC and of authorities having jurisdiction. The
Company does not inspect Customer premise wiring. Where inspection is available, the
Company requires the Customer to have the premise wiring inspected and approved by the
authorities having jurisdiction before requesting connection to the Company's service. Where
inspection is required, the Company is not allowed to connect to the Customer's installation until
it has been inspected and approved by the authorities having jurisdiction
The Company reserves the right to refuse connection to any new installation and/or to
disconnect from any existing service, should the Company learn that the wiring is unsafe or that
it has not been approved. The authorities having jurisdiction also have the right to require the
Company by written notification to discontinue service to an installation which has been found
unsafe. The Company is not liable for any damages incurred when electrical service is
discontinued under order of the authorities having jurisdiction. The Company accepts no
responsibility for injury or damage to the Customer's premises or to persons on the Customer's
premises resulting from defective wiring or equipment.
Grounding of Service Equipment
2.2.3
The identified neutral conductor and metallic parts of the service equipment, including all meter
sockets, and instrument transformer enclosures, shall be effectively grounded. All grounding
shall be bonded together.
A driven ground rod is preferred by Company and is shown in drawings in §7 (Overhead
Services) and §8 (Underground Services).
15 of 1032018 Edition
The Company reserves the right to refuse installation of service contingent upon inspection of
Customer’s grounding connections.
Grounding requirements are shown on many of the drawings in the Customer Installation
Standards.
A grounding conductor (#6 CU minimum – refer to NEC for correct sizing) that is free from

Voltage Categories and Customer Equipment
Section 5
General Comments
5.1
Any type of service or voltage not defined as the Company's standard voltage may be supplied
only after specific written approval is obtained from the Company.
Equipment operated at the Customer's service voltage should be designed for operation at that
voltage.
Voltages for Lighting
5.2
The recommended service voltage for lighting is 120 volts. Customers served by higher
voltages may use 208, 240, 277, or 480 volts for lighting. Where the lighting voltage is different
from the voltage supplied by the Company, the Customer will install and maintain suitable
transformers on the Customer's side of the point of delivery.
Voltages for Heating, Instant Water heating units, and Car Chargers
5.3
The recommended voltage for space and water heating, ovens and Car chargers is normally
208 or 240 volts, depending on the service voltage. Higher voltages, as available, may be used
for larger loads.
Units rated 30kVA or larger should be three phase. Prior to purchase of equipment, consult the
Company for service to units rated 15 kVA (60 amps) or higher, and when the newly added
units bring the total load over 30 kVA. See §5.5 & §3.3.
Voltages for Motors
5.4
Consult the Company before commitments are made for all single phase motors over 6½ hp,
three-phase motors over 30 hp and for any motor that may have requirements not suited for the
available service near the Customer location.
Motors larger than 30 hp should typically be served with a three transformer bank or three
phase padmount transformer and not an Open Wye – Open Delta bank. The customer may be
required to pay any additional cost required to provide this service, such as installing a third
primary phase. Motors with no service factor are more sensitive to small phase voltage
unbalances and voltages below nominal.
Table 5.4 offers a general guide for selection of motor voltages for various horsepower ratings.

Voltages for Special Equipment
5.5
Consult the Company before specifying or purchasing welders, elevators, hoists, electronic
transmitters, x-ray machines, draglines or any apparatus with highly fluctuating load
characteristics. In some instances, the most practical solution to problems associated with
fluctuating loads may be the installation of additional facilities including dedicated circuits from
the substation to serve the Customer. Should the Company install such additional facilities; the
Customer will be required to pay for them. Also consult the Power Quality Standards for Electric
Service.
Wired-radio, or any related means of transmitting information, shall not be connected or coupled
to the Company's lines except by special arrangement with the Company.
Consult the Company for service to commercial radio, television and cellular facilities.
Voltages for Loads Served from Network Area
5.6
Customers in network areas typically will be served at 120/208 volts, single phase, two or three
wire, or three-phase, four wire. In some networks, 277/480-Volt service may be available. In
Mississippi and Arkansas 125/216 Volt service may be available. Individual loads 300 kVA or
more may require installation of transformers in a vault on the Customer's premises. Contact the
Company to arrange for such an installation, to learn what voltage is available, or to request
service at another voltage.

7.1
Consult the Company for the closest and most reasonable location for the service drop
attachment. Ordinarily, only one type of service and one service drop is permitted to the
Customer's premises. The Company will normally make connection to the Customer’s service
entrance conductors. Connection shall be made only after the Customer's wiring has passed
inspection and has been approved by the authorities having jurisdiction. From the point where
the Company's overhead service drop terminates, the Customer shall install service entrance
wires to the meter socket and service entrance switch or circuit breaker panel in accordance
with the requirements of the NEC, NESC, or other authorities having jurisdiction.
Not less than three feet of each conductor of the service entrance cable or wires shall be
left extending beyond the weather head for connection to Company's service drop. For
polyphase services, like phases shall be appropriately identified and marked. Neutrals
shall be marked with white tape on both ends. Neutrals may be bare wire. The Company
will make the connection(s). Refer to Drawing D7-1 and Drawing D7-2 for overhead
residential installations.
It is the customer's responsibility to ensure that like phases are appropriately marked and
connected together on the line side and the load side of the metering equipment.

support of service drop conductors it shall be of adequate strength and supported by braces or
guy wire to withstand safely the strain imposed by these drops (see §2.2.4) and be no higher
than 60” higher than the roof. Where the raceway type service mast is used, all raceway fittings
shall be identified for use with service mast. Rain type service head shall be used at the point of
connection to service drop conductors.
For temporary overhead service refer to §4.5, Temporary Service, and Drawing D4-1.
For permanent service, see Drawings D7-1 and D7-2.
Clearances
7.3
The point of attachment of the service drop (0-750 Volts) shall be high enough to allow for the
service drop conductors to have the following required clearances at their lowest point (To allow
for typical cable sag, point of attachment is usually 1 1/2 -2 ft higher thanthe required clearance
below- consult the Company):
12 feet over areas of pedestrian traffic, residential driveways, and commercial areas not subject
to truck traffic
18 feet over roads, streets, alleys, non-residential driveways, and other areas subject to truck
traffic.
Where the height of a residential building does not permit service drops to meet these values,
the clearances may be reduced to the following:
150V or less to ground
For residential driveways only
(limited to vehicles less than 8 feet)
Spaces accessible to
pedestrian traffic only
Insulated Service drops 12 10
Insulated drip loops 10 10
If vehicles over 8 feet are expected, higher clearances are required consult the Company.
The point of attachment shall never be installed so the service drop would extend over a
swimming pool or any other permanent or temporary structure. See §2.3 Distance
Requirements for Customer Structures.
Length of Service Drop
7.4
The clearance of the unsupported length of the service drop from the Company's facilities to the
first point of attachment will in no case violate the clearances given in previously. The allowable
unsupported length of a service drop shall depend on wire sizes as shown in the table on
Drawings D4-4, D7-1, D7-2, D7-3 and D7-4. Other significant factors and conditions at the
Customer's property may affect these standard lengths. Consult the Company for length
limitations.
31 of 1032018 Edition
Method of Attachment
7.5
The service drop shall be attached to the building or approved extension by suitable means
supplied by the Customer. The Customer shall provide suitable reinforcement or backing for
secure mounting of attachment fittings and adequate anchorage of the service drop. The service
drop shall be at the appropriate height with the appropriate separation. Refer to Drawing D7-1,
Drawing D7-2 or Drawing D7-3 for residential installations.
For loads where parallel phase and neutral service entrance conductors are installed, the
Customer shall consult with the Company early in the design phase to determine how many and
the sizing of conductors that may be brought out for their system.
Company approved, Customer furnished connectors, moles, buss duct or junction box should
be required for loads that exceed four conductors per phase.
Extension of Overhead Distribution Facilities
7.6
The Company standard for overhead distribution facilities is installation on front lot easement.
Consult the Company early in the design phase for more information on other options.
A Customer's service location may require the Company to incur expense greater than normally
allowed in providing the service. Theextension of primary overhead distribution lines, relocation
of Company facilities or removal of Company facilities are some examples. When such a
situation exists, the Company may require payment from the Customer in addition to the amount
