Our 5 year old? 10.8kW Electric shower decided to die this week. I have bought a replacement 10.8kW shower and have a few questions regarding its installation.
The original 10.8kW shower was fitted in 2002/2003 when we had our bathroom replaced. We had a new circuit installed for it as we did not previously have an electric shower.
1) Am I allowed to replace the old shower with the new myself or will I be breaking "Part P" of the Building Regulations?
If am not allowed then end of questions, time for a phone call.
However if I can replace it myself I shall continue...
The circuit installed for our shower is as expected -almost: 10mm cable, 30mA RCD and the confusing part a 40A fuse. I found the original install requirements for the old shower and everything checks out except the 40A fuse, the installation manual indicated a 45A fuse should have been installed for the 10.8kW shower model. The new shower also wants a 45A fuse to be present.
2) Will the new shower be able to work with this fuse too?
3) What is the worst that can happen? I connect everything up as per instructions, turn the shower on and the fuse trips. Time for the original phone call...
Thanks in advance for any help and advice you can give me.
