Conductor Sizing
Pass Thru Box to AC Disconnect (for an 9 panel circuit):
Nameplate maximum continuous output current:
1A
Maximum Output Power 250 Watts AC
250 W ÷ 240 V = 1A
1A x 9 inverters = 9A
8A x 125% = 10A
#10 THWN-2 Table 310.16
40A (90ºC column, see note 240.4(D))
Conduit fill adjustment Table 310.15 (B)(2)(a)
Use .8 for 4-6 current carrying conductors
40A *.8 = 32A
Temperature correction factor Table 310.16
32A x .77 = 24.6A
Overcurrent Protection Device per circuit
1 - 20A two pole breaker Per Manufacturer Specification
