Hello,
3 PV inverters with [2] at 16A output and [1] at 28A output are combined in a
125A PV Dedicated Panel via [2] 20A 2pole breakers and [1] 35A breaker.
Building is a office building with 240V and 200A Main Service
The wire I am tapping onto are 90c rated 2/0cu
Using 2008 NEC, NY.
There is a 100A AC Disconnect fused with 80A fuses.
My question is for sizing the wires between the AC Disconnect and the Utility meter.
Should the wire be a #4cu or a #3cu or a #1cu?
110.14(C)(1)(a) if terminal derate and "not a service feeder" then #1?
vs. Table 310.15(B)(6)
I believe it is a #4
as it is a new service and Table 310.15(B)(6).
