As long as when the contacts are closed you don’t have crossed polarity then no.Hi, I'm just about to fit an MCG 63A type A, C curve, 2 pole RCBO (Awaiting from CEF) for a new 10mm SWA supply from my meter cabinet. The data sheet says the incoming supply can be either top or bottom. - That's okay, but it does not show which polarity for N and L, just 1,2, 3, 4 on the small picture test circuit. My question is does it matter?
So from memory 1-3 & 2-4 correspond.
