I'm building all-electric >2,000 sq ft single family home on a vacant 2 acre parcel in Northern California. My plan, which my local utility (PG&E) has approved, is to install a permanent customer owned (CO) pole about 15' from an existing PG&E pole near the corner of my property. The CO pole, which is approx 100' from the future house, will provide temporary power during construction as well as permanent power once the house is completed. A meter base and load center panel will be mounted on the pole (pedestal style) and the PG&E meter and main load center panel will stay there after conversion to permanent power. 200 amp permanent power will be undergrounded from the CO pole to a 200 amp interior subpanel at the house. PG&E intends to set up our temporary service from their side of the meter as if it was permanent service, so their transition from temporary to permanent power will just take an administrative/rate change.
Here are some additional details:
Permanent Customer Owned (CO) Pole: 25' 200A Class 6 PG&E Pole
Panel on Pole: As suggested in other post (Thanks ThreePhaseEel), considering the Milbank U5169-XTL-200 however open to other suggestions. A local power pole installer suggested a 200-Amp Cutler Hammer Meter Base & Load Center with 4 Space Circuits and 8 Single Pole Circuit, but it is not clear whether this can be used for permanent power.
Outlets at CO Pole: For temporary power, I probably only need one 20 amp circuit for two 110v outlets and one 30 amp RV outlet box. I'd like to keep these outlet in place once I set up permanent power to the house.
Temp Power Configuration: Given the CO pole and outlets will be over 100 ft from the building pad, I plan to run a 30 amp 100' connector cable from the CO pole to the pad and hook up a 30 amp spider box.
Feeder Line for Permanent Power to House: 350 KCMIL XHHW-2 aluminum wire feeder wire placed in 2" Schedule 80 PVC conduit. (Planning for 310A amperage capacity instead of 250A to address voltage drop along the 100' distance from main panel to subpanel.)
Subpanel at House: 40-space or 42-space, 200A, interior main breaker panel
Here is my main question: What is the most optimal way to configure the meter/load center panel for temp power so that minimal (if any) reconfiguration is needed when we hook up permanent power to the house? I received a couple bids for CO pole/temporary power install and I don't feel like I've gotten a clear answer about how best to convert the panel setup to permanent power (installers just focused on temporary power). At the minimum, I want a disconnect at the meter to cut off power to the house subpanel which is not a typical feature of temp power panel. Any input on any aspect of this project would be appreciated.
Thanks to those who contributed to Martin Vandepas's "Is it better to install temp service or permanent outdoor service with future home as subpanel?" thread which I've reviewed closely and incorporate responses there into my existing plan.
