2.1
Temporary Construction Services a.
The City provides temporary construction power where electrical service is required for a period of
12 months or less . The customer must complete and submit a Request for Electric Service form to the City allowing sufficient time for evaluation and response. b.
The customer shall post the address on or near the temporary power. Posting shall be large enough to be seen from the road. c.
The customer shall install the temporary power facility within 2 to 3 feet of an underground electric source. If a transformer will be the power source, please locate the temporary to the right of the transformer as you face it from the front. For overhead services, the customer installs an overhead temporary pole a minimum of ten feet from an existing pole. The temporary facility must meet the requirements of drawings SM-101 or SM-102. The temporary pole height for overhead installations must allow for the service wire to meet minimum service drop clearance requirements. d.
The customer should provide a minimum of 40 inches of conductor length exposed at the end of the flex-conduit/weatherhead, with the neutral conductor clearly indicated and a total length sufficient for termination at electric source. A construction deposit may be required and will be collected at the Service Center prior to approval of a building/electrical permit.
2.2
Residential Development Construction Power a.
The developer, contractor or electrical contractor shall furnish and install the temporary meter pole in proximity to power service (power pole, handhole, etc.). The temporary meter pole must meet
City and NESC requirements. b.
The building inspector will inspect the installation and Water & Power will set the meter, make final termination and energize the installation. c.
The standard service voltage of single-phase 120/240 three-wire service is available for temporary residential construction power applications.
2.3
Commercial Development Construction Power a.
The City will prepare a cost estimate for the installation upon receiving the Request for Electric
Service and an engineering deposit .
The customer must pay the total estimated cost of the project prior to release of materials or installation. When the final cost is determined, the customer will be billed or refunded the difference between the estimated cost and the actual cost. The developer, contractor, or electrical contractor shall furnish and install the temporary meter pole in a location agreed to by the City. The temporary pole must meet City and NESC requirements. Frequently, the costs of construction temporary power can be included in the cost of the permanent power. b.
The standard services for temporary construction power applications are single-phase 120/240V or 3phase 120/208V wye. Contact Water & Power for special applications. Temporary 277/480V transformers will not be installed. c.
The temporary pole must conform to all current regulation of National Electrical Code and National
Electrical Safety Code, including ground fault protection.

d.
The meter socket must include a lever-operated bypass. Any 120/208V three-wire service shall have a five-jaw meter socket. The fifth jaw shall be installed in the 9 o’clock position and connected to the neutral. e.
The City prohibits meter installation on any of its utility poles. f.
The City’s building inspector or state electrical inspector will inspect the installation. Upon inspection approval, Water & Power will set the meter, make the final termination, and energize the installation. A construction deposit may be required and will be collected at the Service Center prior to approval of a building/electrical permit. g.
Typically, the City shall make the connection within three working days unless a line extension of the system is required to provide the power. h.
Contractors shall install all metering equipment except the meter. i.
All service installations must have an approved meter socket with sealing mechanism. j.
All meter locations shall be approved by the City prior to construction. k.
All meter equipment must be installed in readily accessible locations. l.
Each meter shall have a separate ground rod.
2.4
Inspection Notes a.
All service raceways containing service laterals need to go directly from the utility supply source to the meter enclosure. The NEC does not allow unprotected conductors to be run through the breaker panel where protected conductors are located. (Art. 230.7; Raceway definition, Art. 100) b.
All metal service raceways (raceways containing service laterals or conductors) need to be bonded with a bonding bushing and a bonding jumper, regardless of whether eccentric or concentric knockouts are present. For service bonding requirements see NEC 250.92 and Table 250.66. c.
In-use weatherproof receptacle covers are required for all 15- and 20-ampere, 125-and 250-volt receptacles on temporary meters. [Art. 406.8 (B)] d.
All 125- and 250- volt, 15-, 20-, and 30-amp receptacles shall have GFCI protection. [Art.
590.6(A)] This also includes temporary power installed in a building under construction.
Basically, ALL requirements for permanent wiring found in the applicable NEC apply to temporary installations. [Art. 590.2 (A)]
