Chris Asked :Can anyone help me, do I need to upgrade my wiring if I have 8kw to a 9kw electric shower ?
Answered By Jasbir :
This shower is rated 9kw at 240v. UK electricity is 230v, at this voltage the shower is rated at 8.3kw (from Mira website). You must have a 40amp fuse at the fusebox. I assume you have min. 6mm cable, this should be ok but length and fitting method can limit load capacity. If you are not sure then ask an electrician, but the short answer is that it “should” be ok. Excellent shower by the way!

Depending how far your shower is from your main fuse board you. Should have a 6mm or 10mm cable. Mira helpline will be happy to tell you.
