I have bought a Grant external boiler for the renovation.
I have a couple of questions re the electrical connection.
As regards supplementary bonding to the oil feed pipe, is this required if the boiler is outside? The internal plumbing will be all plastic after the first metre.
The manual states that "The electrical supply to the boiler and control system should be fed from a single separate 5 Amp circuit breaker with earth leakage protection providing complete electrical isolation". Also a fused double pole switch should be used. I was planning to just use a FCU on the downstairs ring to provide power. Is the separate circuit breaker (MCB?) really necessary?
Cheers
