wiring an electric shower

sixtysix

could you wire an electric shower off the immersion wiring
or should it always be wired back to the fuse box?

Stoner

never off the immersion,
if its a pump shower like a triton t 90i , 6 sq T+E cable back to the board fed from a dedicated 40 Amp RCBO - many evenrequire 10sq T+E , or is might be a pump on a mixer shower, ie electricity is required to pump the water only as the heating system heated it, then a 2.5 sq mm t+E cable , even a 1.5 sq back to the board

Depends on what you want, a shower or suicide?

Stoners advice is correct electric showers draw an enormous current when in use and if you use the wrong spec cable there is a very real risk of fire or electrocution. It is also vital that the shower is wired to it's own RCD in the distribution board the RCD is your only real protection against being fried in the shower if something goes wrong. I would advise against you doing this if as I suspect you have only basic electrical experience. It's not an especially hard job to do but getting it wrong can have dire consequences.

If you need to ask a question like that, then you need to get an electrician to do the job.
Very few second chances mixing water and electricity.
