cable rating

[anisalfa]

I'm wiring up a power shower(not heater) and would like to know what amperage cable to use. Unit says Rated: 120w @ 230v..

Any help would be most appreciated..

Thanks

stick a fcu with dp switch on the ring or on a 2.5mm spur from the ring (outside the bathroom) fit a 3A fuse in the FCU

from here run with 1.0mm twin and earth cable to a junction box near the pump (which should be concealed for example behind a screwed on bath pannel)

if the unit comes with a flex connect it here
if the unit does not come with a flex use 1.0mm flex for the final run into the unit

If the ring you're connecting to is not RCD protected, use an RCD FCU.

Is it necessary to have the FCU outside the bathroom? Zone 3 is sufficient surely.

Otherwise every electric towel rail or quartz heater in the country is against regs!

Note what Plug says about the bath panel being screwed on. If you can remove it without tools then you can't use a standard junction box behind there.

i think zone 3 is ok but its still something i would avoid if possible
