That's why it is called a GUIDE. Its to help the hard of thinking from actually having to know what is actually in BS7671.Back to the matter in hand, I can't find anything in BYB or OSG.
But Electrician's Guide to The Building Regulations advises;
4.5 "Instantaneous water heaters (including showers) of rating exceeding 3 kW should be supplied by a separate circuit. Local isolation of water and electricity should be provided to facilitate maintenance"
So should I conclude no reg; Therefore, common sense should prevail?
