Hi all
I have a combi-boiler recently wired up to a circuit that keeps tripping the MCB but I can't understand what it can be...
The only appliances on the circuit that I am aware of are the boiler and an extractor fan (small bathroom type).
The boiler has a fused switch with the extractor fan spurred off with a fused switch. I believe all fuses are 3A (the internal boiler fuse is either 2 or 3A) and the MCB is 15A.
I am unaware of any other appliances on this circuit (I will turn MCB off and test all my switches, sockets etc tonight to be 100% clear) and it is an intermittent problem.
On two occasions the MCB adjacent to the boiler MCB has tripped as well (a red herring?? Can the force of the trip knock an adjacent MCB out?)
I am a bit baffled as if the only appliances are the extractor and boiler, why aren't they blowing their lower rated fuses?
Cheers for any help.
Dave
