Advice on current NEC codes to clear up wire size and service issue
I live in Northern California and have a Rural Owner Builder permit and am in the process of setting our power pole and Meter panel for imminent PGE connection, (after sign off from County).
I have requested a 200A supply and have gone back and forth with several people all who have been very helpful in suggesting the appropriate wire size and I found out today that Humboldt County requires only two hot legs and a neutral leg (all same size- 3 wire) from pole through Meter panel via buried 3 "conduit to house Main lug loadcenter both Meter panel and Loadcenter will be 8' Cu ground rod earthed The Loadcenter is 210ft away from the hand off I will get at the pole weatherhead from PG&E.
I was informed by a member today that according to NEC 310.14(b)(6) for 225A service you need 2/0 copper. He stated that this does
not take into account voltage drop, and I will likely want to upgrade in
size to account for the distance. Going up to 3/0 will more than
likely be completely adequate in the real world. I fully agree.
Is this NEC section applicable now as of March 2009 for the wire sizing.
I want a 200A supply and will run three legs of 3/0 Copper and hope an electrical contractor will sign it of as from the county today after mentioning 200A service and 210ft run I was quoted 250kcmil ( 4 times larger than 3/0!!!) So who will sign this off if I run all conductors 3/0 Cu
