Can someone please confirm that my plan is up to code?
Current 100A aerial service to house from pole. No electric in detached garage.
Install new 200A panel in garage. Install new grounding rod at garage. Install meter base on exterior of garage. Install either 2-1/2" for Al or 2" for Cu rigid galvanized riser/mast from meter base through roof. Install 4/0 (Al) or 2/0 (Cu) in riser/mast and terminate on line side of meter base. Install 4/0 (Al) or 2/0 (Cu) from meter base to panel and terminate on load side of meter base and in main breaker.
Install 2" rigid galvanized conduit between garage and house underground to a depth of at least 6" (per NEC 2008 Table 300.5 Column 2, Row 1). Stub up underneath attached deck. Transition to PVC. Attach conduit to bottom of deck every 32 inches (every other joist). Penetrate building envelope. Route conduit to existing panel.
Install 2/0 Al or #2 Cu from garage main panel to existing panel in house. Terminate said wire on 100A breaker in garage.
Call utility company for disconnect at house.
Remove green screw bonding nuetral to ground in the house. Terminate wire from garage to 100A main breaker in house.
Move meter.
Get inspection from City.
Call utility for reconnect at garage.
What have I not covered?
Thanks,
Jason
