Residential PV disconnect requirements
I have a 4 wire 120/240 do I need a 2 pole or a 3 pole disconnect switch one person told me that I needed a 3 pole and run the neutral through the disconnect switch.Is that NEC code?
For grid interactive systems See 705.20 in the NEC, the disconnecting means for the PV source shall disconnect the ungrounded conductors. Since the system has a solid neutral connection to the utility service, it is considered a nonseparately derived system.
