9.5kw draws a lot of current so correct size cable is very important.



9500w Divide by 230v = 41.3 amps. just for anybody who might wanna work it out :)

10mm cable, MUST be on its own circuit, protected by an RCD or MCB at the very least.
The pull cord is just an isolator, you still need this aswell as the MCB/RCD as the pull cord doesnt offer short circuit/overload protection.

I would be very surprised if your current shower isnt on its own circuit.

When ever we installshoers at work they are to their own mcb/fuse.

I would if I was you, better safe than sorry.

Should a 9.5kw leccy shower always run it's own cable into a seperate fuse/trip switch in junction box ?

At moment

Electric shower (don't know KW), the wiring comes from the shower into a pull switch on roof and then down to leccy box...Now as far as I can see it is not controlled in the box by a seperate fuse / trip switch.

Bought a new shower (9.5kw) and on instructions says it should be on a seperate cable and into a seperate trip / fuse of it's own..Or the circuit could heat up.

So is this really neccesary when it goes through the switched pull cord in bathroom..

I am assuming the shower at moment just runs through the ring main of the house as there is no seperate trip / fuse for it...there is seperate fuses for all the heaters and the hot water etc..

So do i need an electrician out to fit a new wiring from shower down into box and seperate fuse / switch?
