Hi there,
I would like some advice on the Earth Neutral bonding for a Sunsynk 5kW inverter. There is a lot of debate surrounding using relay vs permanent bond. If using a relay for the bonding however, what rating should the relay be? I have seen a few photos where a 10A relay is used. Others suggested based on the inverter power (in my case then, 25A), although if current would flow between this bond, this should trip your Earth leakage, right? I was considering a 20 Amp DIN rail relay.
Additionally, what should the wire rating be for a) the wire creating the N-E bond (probably related to the relay rating).
So my questions are:
a) N-E bond relay A rating
b) N-E bond wire rating (probably depending on to the relay rating)
c) The rating for the wire that is used for the relay coil (connected to ATS 240)
