the application, it will then be necessary to submit two photographs — one view

of the exterior, and one of the interior. One photograph will be accepted when

the article has no removable housing. Each photograph to be 8 x 10 inches in size.

Destruction of Samples If samples are damaged due to tests, the loss so incurred will be borne by the applicant.

The Commission will, when it deems necessary, retain one of the samples submitted.

Service in General

1. For direct or alternating current circuits of 600 volts or less, all conductors from the point where they enter the building to the point or points at which the service, or a sub-service, terminates shall be protected throughout by installation in metal conduit or other approved duct or supported in an approved manner.

2. All service wire and cable joints must be soldered and covered with an insulation equal to that on the conductors. All joints shall be soldered unless made with some form of approved splicing device. All service equipment shall be mechanically secured in position.

3. Metal conduits containing service wires must be insulated from the metal conduit, metal moulding, or armored cable system within the building and all metal work on or in the building, or they must have the metal of the conduit permanently and effectually grounded. The ground connection to be independent of and in addition to any other ground wire on metal conduit, metal moulding or armored cable system within the building.

Overhead Services

1. Wires and cables, when they enter buildings at services, shall have drip loops outside, and the entrance holes through which they enter shall be bushed with non-combustible, non-absorptive insulating tubes inclined upwards, towards the inside, or the service wires may be brought into buildings through a single iron conduit, in which case the conduit will be equipped with an approved service head, except where duplex or triplex service cable with an approved type of insulation is used. The inner end of the conduit system shall extend to the service cutout, cabinet or switchboard.

2. Where a row of separate buildings is to be supplied from an overhead main, one service cable may be run from the main to the buildings and from the first attachment to a building; a sub-service main may be extended in conduit along the outside of the buildings. One main service cable shall supply not more than five buildings except by special permission of the Commission.

3. Service wires must be at least No. 10 B. & S. Gauge, and if No. 6 B. & S. or smaller, must consist of multiple conductor cable.

4. Service wires extended on the exterior walls of buildings shall be run in approved conduit or supported on petticoat insulators of an approved type, placed not more than fifteen feet apart.

Underground Services

1. Underground conductors shall be protected from moisture and mechanical injury when brought into a building.

2. Service tubes shall have the ends so closed as to prevent the entrance of gases into the building.

3. Where a row of separate buildings is to be supplied from an underground main, one service cable may be run from the main to a building and enter as a service, and from this point a sub-service main may be extended underground or in exposed iron pipe outside the buildings, or under or along or within the building walls, provided that at all times the cable is protected with two inches of brick or concrete.

Service Switches, Cut-outs, Circuit Breakers for Scrrices of 600 Volts or Less

1. On constant potential circuits, all service switches must be so arranged that the fuses will protect, and the opening of the switch will disconnect all of the wires, except permanently grounded wires.

2. When installed without other automatic overload protective devices, automatic overload circuit breakers must have the poles and trip coils so arranged as to afford complete protection against overloads and short circuits. In two or three phase three-wire circuits and two-phase four-wire circuits there must be a trip coil in each phase. If a circuit breaker is used in place of the switch, it must be so arranged that no one pole can be opened manually without disconnecting all the wires, except permanently grounded wires.

3. Switches, cutouts and circuit breakers must, when placed where exposed to mechanical injury or in the immediate vicinity of easily ignitable stuff or where exposed to inflammable gases, or dust or flyings of combustible material, be mounted in approved cut-out boxes or cabinets, except oil switches, circuit breakers, and similar devices which have approved casings. All devices which produce or create sparks or arcs must be placed in approved vapor-proof enclosures.

4. Switches, cutouts and circuit breakers must, when located where exposed to moisture, unless they are moisture proof, be mounted in approved cut-out boxes or cabinets.

5. Automatic cutouts must be placed on all service wires, except permanently grounded wires, either overhead or underground, in the nearest accessible place to the point where they enter the building and inside the walls and arranged to cut off the entire current from the building, except where it is legally required that fire alarms, fire pumps, exit lights, etc., be connected ahead of service switches.

6. Service switches must indicate plainly whether they are open or closed.

7. Single-pole knife switches must never be used as service switches.

8. Single-throw knife switches must be so placed that gravity will not tend to close them. Double-throw knife switches may be mounted so that the throw will be either vertical or horizontal, as preferred, but if the throw is vertical, a locking device must be provided, so constructed as to insure the blades remaining in the open position when so set.

Service Transformers

1. Transformers must not be attached to any building where the potential exceeds 600 volts, except by special permission and when attached to a building must be separated therefrom by substantial supports.

2. Oil transformers must not be placed inside of any building unless located in a transformer vault that has either received specific approval or has been constructed in accordance with an approved design.

3. Air cooled transformers must not be placed inside of any building unless installed in an approved transformer vault and mounted so that the case shall be at a distance of at least one foot from combustible material or separated therefrom by a slab or panel of non-combustible, non-absorptive, insulating material.

4. Transformers permitted inside of buildings must be located as near as possible to the point at which the primary wires enter the building.

5. Transformer vaults must be constructed of fire-proof material. The enclosure shall have no opening to the building, except through an approved tight-fitting fire door. It shall be ventilated in some approved manner, used only to contain transformers and other service equipment and be kept securely locked to prevent access by other than responsible persons. Suitable oil drains or guard sills shall be provided when necessary.

6. Transformers installed in vaults shall have their cases permanently and effectually grounded.

Grounding

1. The grounding of low potential circuits under the following regulations is only allowed when such circuits are so arranged that under normal conditions of service there will be no appreciable passage of current to ground.

2. Transformer secondaries of distributing systems (except where the primary voltage does not exceed GOO volts) must be grounded provided the maximum difference of potential between the grounded point and any other point in the circuit does not exceed 150 volts and may be grounded when the maximum difference of potential between the grounded point and any other point in the circuit exceeds 150 volts. In either case, the following rules must be complied with:

(a) The grounding shall be made at the neutral point or wire, whenever a neutral point or wire is accessible.

(b) When no neutral point or wire is accessible, one side of the secondary circuit shall be grounded.

(c) The ground connection shall be at the transformer or on the individual service or on a system ground wire connected to the grounded conductors of many secondary mains.

3. Ground wires shall be copper and never less than No. 6 B. & S. Gauge, and have an approved insulating covering.

4. The ground conductors for three-phase systems must not be smaller than one-fifth the size of the wire to which it is attached nor smaller than No. 6 B. & S. Gauge copper wire, and need not be larger than No. O. B. & S. Gauge copper wire.

5. The cases or frames of transformers used exclusively to supply current to meters shall be grounded unless they are installed and guarded in all respects as required for the higher voltage circuit connected to them.

6. Ground connections to metallic piping systems should be made on the street side of water meters, but connections may be made immediately inside building walls to secure accessibility for inspection and test. When water meters are located outside buildings, or in concrete pits within buildings where piping connections are imbedded in concrete flooring, the ground connections may be made on the building side of the meters, if they are suitably shunted.

Location of Meters 1. Meters shall be installed in a clean, <Jry, safe place, not subject to vibration or great variations In temperature.

2. Where it is necessary to install meters in locations exposed to weather conditions, they shall be protected by suitable boxes or cabinets.

3. Meters should be easily accessible for reading, testing and making necessary adjustments and repairs.

Exceptions to one or more of the rules contained herein can be obtained only by permission of the Commission and any conditions not covered by these rules shall be specially considered and must be approved by the Commission.

When, in the judgment of the Commission, after due inspection, any appliances, devices, transformers, switches, meters or circuits included in service equipment are unsafe or dangerous to persons or property, the Commission, after notifying the corporation and allowing a reasonable time to put same in safe condition, shall cause such to be disconnected from the electrical source and seal same to prevent their use. When so disconnected and sealed the electrical corporation shall not cause or permit their employees to connect or put in use any service equipment until the same has, in the opinion of the Commission, been made safe and the electrical corporation advised in writing to that effect.

Further ordered, That the Electrical Engineer of the Commission be and he hereby is authorized to certify in the name of the Commission the approval of electrical devices submitted pursuant to the provisions of this order without further action by the Commission.
