Hello.
Ive just got back off a job, I narrowed it down to the immersion heater element causing a b16 60898 mcb to trip.
I disconnected the thermostat to see if that was causing the problem first which in this case it was'nt.
I then put the terminals straight on to the element terminals to narrow the fault down.
I switched the mcb back on and this time i didnt trip.
I noticed i had wired live and neutral differently to how it was so i swapped them around to see if it tripped again and it did.
So yes surely a fault element?
Anyone know why swapping the polarity around causes the element to heat up not trip the mcb?
You cant see which terminals are marked L and N.
I bought a new element but found it impossible to undo it.
The customer has told me nothing has been tampered with and its been there for a good 10 years plus.
Ive disconnected everything for now and left it dead.
Cheers James.
