its got to be the supressor, took it out and still not tripped rcd.
only found it cos i was flicking the switch on off a few times and started tripping straight away. thats when i removed it and found it was knacked shorting across N E.
thanks for the quick reply, i see what you mean about the thermostat. i can see this fault driving me nuts, its an elson tank too. what can cause earth leakage? fault cable's?
Hi all,
Got a customer with a horrible fault. The system is a myson housewarmer back boiler, gravity hot water, pumped central heating. randall 3020p timeswitch no room/cylinder stat
The problem is the RCD is tripping aswell as 2 3amp fuses blowing. 1 fuse spur and another for the pump...
