wiring rule for a shower pump

[mike67]

I need to fit a shower pump in my house, the pum needs a 30ma RCD, power via a double switched fuse with a 13Amps. I have a 13A isolator switch which will be in the hot press next to the pump and a cable from this switch going to the distribution board where I already have a 30ma RCD 40Amps. My question is I am doing right by connecting a 13A isolator to a 40Apm 30ma RCD? what section of cable should I use for about 10m lenght.

mike what power rating is the pump?

Besides that, from your 40A MCB to FCU 13A to pump should be fine.

Where abouts at home are you, purely out of interest

Hi Mike

Your pump will draw amaximum of 6.2amps, try a 5amp fuse in the FCU, if this gives up revert to 13amp (check the manufacturers guidance as well)

Look forward to hearing from you re tickets, very much appreciated wether you can source some or not

in fact what i was asking in my second questions is knowing that my FCU is about 10m away from the MCB what seize of cable should I use to bring the power.
