  B. Support exposed plastic at entry and exit points.

  (1) Plug the space between the plastic and the casing pipe (see GDS A-90, “Polyethylene Gas Distribution System Design”) with casing plugs or cable protectors, duct seal, or other suitable means not detrimental to PE pipe.

  (2) Support any non-cased plastic pipe with backfill.

  C. Plastic pipe is approved for double insertion into existing mains and services. This application is approved only if the following conditions are met:

  (1) It is not practical or economical to remove the previously inserted pipe.

  (2) The installation is made per GDS A-75, “Gas Service and Mains in Plastic Casing,” or GDS A-90, as applicable, particularly with respect to protecting and supporting the entry and exit points.

  (3) The installation is mapped with both the casing size and casing material identified. For example, a ½ in. plastic service inserted into a 1 in. copper pipe that is inserted into a 2 in. steel line is mapped as shown in Figure 1.

  Figure 1. Mapping of a Double Insert

  D. Squeezing of the outer casing is only allowed in the event of an emergency. If the outer casing pipe is squeezed, the casing must be grounded. The PE gas-carrier pipe must be replaced after flow control is no longer needed.

A PG&E-approved polyester, flat pulling tape, white with sequential footage markings every foot, and 2,500-pound minimum tensile strength ( Code M560154 ), must be installed in all conduits and attached to an end cap.
  10. Install a splice box whenever cable pulling tensions are exceeded, or a change in cable or conduit size is required. The applicant must contact the local PG&E office to determine these requirements.
  11. Test bypass facilities are required for both single phase and three phase non-residential installations regardless of the panel ampacity.

  PG&E Requirements

  12. If PG&E service conductors are to be run in a multiple conduit system, all phases and the neutral must be installed in each conduit that is used.

  13. PG&E will furnish and install the underground service conductors and make connections in the applicant’s service termination enclosure.

  14. Potential water intrusion into service conduits and meter termination facilities

  A. Water intrusion into service conduits and meter termination facilities may occur if the source side of the service facilities (e.g., secondary splice box) is at an elevation greater than the meter termination facilities.

  B. CPUC General Order 128, Rule 31.6 requires “Lateral ducts for services to buildings, through which water may enter buildings, must be plugged or sealed.”

  C. When the intrusion of water into the service and metering equipment can be reasonably expected through lateral ducts, the conduits must be sealed at both ends using one of the PG&E approved sealing method shown in Document 062288.

  D. If the meter termination facilities are significantly lower than the source side facilities, use the Rayflate Duct Sealing System (RDSS) conduit sealing system listed in Document 062288 .

  B. Permanent Service Poles: Anchor guy only as shown in Figure 13 on Page 12. See Figure 5 on Page 10 for the correct placement of guy.

  C. The guy strain insulator is to be located in a zone: 8 feet or more above the ground; and 8 feet or more below the level of the lowest supply conductor, or 6 feet or more from the surface of the pole and 1 foot or more below the level of the lowest supply conductor.

  Metering Requirements

  23. Meters must be furnished by PG&E. See Greenbook sections 5, 6, and 7 for meter panel and additional metering requirements.

  24. For residential installations, meter sockets without test bypass facilities must be furnished, installed, and wired by the customer as shown on Page 12.

  25. For commercial and industrial applications, meter sockets with PG&E-approved test bypass facilities must be furnished, installed, and wired by the customer.

  26. Customer−owned poles for residential use are limited to only one meter panel rated at 225 amps (continuous) or less. Poles for non−residential applications are limited to only one meter panel rated at 200 amps or less. Residential and Non−residential installations with more than one meter, or a meter panel with a greater ampacity must be installed on panelboard construction as shown in Document 065374. Electric meter panels with a circuit breaker section attached to the right or left side of the meter section, may be required, as determined by PG&E, to provide additional support for the panel on the pole.

  Verifying Depth of Customer Owned Poles

  Applicants who plan to install a new customer−owned service pole prior to inspection by PG&E personnel can use following method for PG&E inspectors to verify the setting depth of newly installed poles that have already been set in the ground. See notes below and Figure 18, “Pole Depth Verification”, on page 17. These installations will be approved at the discretion of the PG&E Electrical inspector.

  27. Install 3/4−inch diameter PVC Schedule 40 conduit from the bottom of the pole to 12 inches above grade level.

  28. Place a removable cap on the top of the conduit and a permanent cap on the bottom of the conduit.

  29. Attach the conduit to the pole using three heavy duty pipe straps and 10D galvanized nails. Place one pipe strap towards the top of the conduit below the removable cap. Place the second strap in the middle of the conduit and the third strap at the bottom of the conduit just above the permanent cap.

  30. Install a PG&E approved pole to, at least, the minimum required setting depth. Refer to Table 3 Pole Setting Depths on page 3.

  31. Ensure the PVC conduit is not broken and remains free of soil, equipment, or other obstacles, throughout the conduit. The conduit will be used to verify the pole setting depth.

  32. Backfill and compact the soil around the pole to 90% of maximum density. Determine the maximum density and the in−place density by the California Test Method No. 216−6, Parts I and II respectively, or by ASTM D−1556 and D−1557 respectively. A copy of the test results may be required by PG&E.

  33. Call for inspection after the installation of the customer owned pole is complete.
