PG&E has verified that with the proposed design that the utility does not need to make any upgrades on the utility’s side of the meter.

Question 22: This question involved multiple questions about power to new Building, as follows:

1.A) Where dose this conduit come from?

NPS Response: The pull box, near the building site, is there to mark and protect the termination point of the 2" electrical conduit running from the meter panel for the new building. The pull box should be removed and the conduit needs to be coupled to and continued approximately 30 more feet and stubbed up into the location for the new buildings electrical panel. Then approximately 300 feet of conductor cable will need to be pulled through the conduit to provide power from the existing circuit breaker in the meter panel to the new buildings electrical panel.
