Can you not just look them up in the regs as surely you should have checked all this out when designing the circuits.

So happy with this depth ???

just had to work out the depth in english, about 8". just the right depth for a sharp spade.

its too late to worry about current carryng capacity when its already installed. Why are you bothered now????
