Hi all
A new shower circuit has been installed into a town property that is a TT earthing set up. The shower is protected by a 60amp 30 ma rcd and a 40 amp breaker. The ZS is 9.8 ohms, the Ze is 9.7 oms. Should this circuit be protected by a further 100ma rcd before the 30ma rcd or is the 30ma rcd adequate.
regards
