Dear community, I hope you are all doing well. I live in the USA and I recently purchased from China a GSL energy hybrid inverter gsl-h-7.6k-US (deye SUN-7.6-8K-SG01LP1-US-EU)
I am very confused by what they are telling me about connecting the inverter to the Grid. They tell me to use a 60/63 amp 2 pole breaker with 6mm2 (10awg) wires. But the US electrical code (NEC) says 4 or 6awg max.
I attached a picture of the inverter label that says the Max AC Input Power 38.3A. The AC Input Rated Current is 33.4 Amp. so I would think that a 40 amp breaker would be enough and therefore 10awg (6mm2) wires would be ok.
I reached out to GSL several times to ask about this and they confirmed that quote "63a circuit breaker can be connected to 6mm2 wire, can be used for AC input and output, 4awg is DC end, connected to lithium battery and inverter
Am I missing or misunderstanding something? What do you all think?
