Customer Question

I have a 50Amp direct feed to a shower heater switch. Having installed a combi boiler this switch is now redundant. What elase can I used this 50A power supply for. It is in my upstairs ceiling so I could connect to some plug sockets in the loft but no idea if the sockets will melt with 50Amp flowing through it or if I plug a hoover into a socket fed by 50A will kill the hoover.
If I can't use it what is the safest way of blanking the live end off?

Hi , yes you can use it for sockets. You would just need to change the fuse to 32amps. You would only be drawing 3kw max at a socket so there is no danger . It is only dangerous when drawing too much power through a cable too small too carry a lot of power. Your cable for the shower would be easily big enough

Is that the fuse in the RCD breaker under the stairs? It seems to have its own trip. 63A 30mA 230v. Do i just pull it out and plonk a new one in there? What size wiring cable should I use for a double socket? The 50A cable is huge and assume need to connect via a junction box...
Cheers

Hi yes, replace the rcd breaker. Pull it out ( some are u see a cover that would have to be removed,usually just a couple of screws, take it to an electrical suppliers and ask for the lower amp one
