RCD Test?should it trip MCB'S

nashy64uk · 6 Dec 2004

Just had a split load cu fitted,when testing the RCD side it trips the RCD switch,but should it also trip out the MCB'S on that side namely the shower,cooker,garage circuit?
Anyone help as i'm not that well up on electrics etc.

The RCD is the first protective device in the system so it will trip before the circuit MCB.
I assume you are testing the RCD, so no the mcb's should not trip at all.
