The electrical wiring for a electric shower is already in place and i wanted to fit one myself
basically i'm not sure if i need to change anything electrical
the cable size is 10mm2
at the consumer unit the shower has an MCB fuse of 40A
at the consumer unit there is a 80Amp 30mA RCCB trip switch
i got the info below from a different site:
Standard Shower Rating (8.5kW)
Watts (kW)
Maximum load from the supply 36.95 A
Maximum size of Protective device 40A
Recommended
Minimum 10mm2
Cable Size to be Used
Protective Device RCBO
if the shower uses 36.96 A would that cause the 30mA RCCB to trip
any help is much appreciated
