Hi
I am upgrading our current shower to a high power shower. We are limited on the MCB that we can use as our crabtree consumer unit is fairly old, and I could only manage to get a 40 amp MCB. The unit itself has
a 100 mA RCD.
Should I install an additional 30 mA RCD
inline with the cable from the consumer unit to the DP shower switch, or is the
100 mA one sufficient. If so has anyone got any recommmendations on what to use ?
