Why is an RCD required between the inverter and final circuits?
Inverter is connected to the incoming supply from the grid via SY cable through trunking to a meter then to an isolator , then to fuses (can't remember the ratings) then via SWA to to a busbar chamber in the intake room.
Not sure if there is d.c./AC separation at the inverter, though there is an indicator led for if there is an earth fault on the d.c. side?
Hi
Without simple seperation between d.c and a.c, a fault on dc could transfer to the a.c side, so a type B RCD must be installed.
