Re: Tell us about your faults !

here's one for ya i just recently went to a property where every time the iron was used after an half hour sometimes an hour and then sometimes longer the main RCD would trip after much testing found to be the surge protection socket on the computer

Re: Tell us about your faults !

recently taken out and replaced a 3036 cu board, done all dead/live test procedures everything fine. customer phoned to say whenever they turn the switch off and then back on again at the switched fused spur connected up on the ring connected to the boiler it trips the rcd. been back out redone all tests checked all cable connections and usual busbar connections all in right place. if the spur switch is left in the on position when the rcd is switched back on the circuit is fine its only if the switch is switched off then back on again, all readings in the live tests are ok. any ideas would be appreciated as you know what its like. customer says its was ok before you changed the consumer unit!!. cheers

Don't you usually get some leakage from old boilers, I thought that's why they are usually left of RCD's?

Re: Tell us about your faults !

Have you changed the spur? Could be its switching the neutral before the live due to burn out on the contacts

I once knew a fella that ran a 3ph machine in his shed. He used his phase then pinched the other two off his neighbours in henly blocks. Time served EITB spark as well.
Absolute bloody genius!!!

Right same job as the meter pic above, fuses in the neutrals and antique boards , the owner is 92 and doesn't fancy the rewire.

Guy in the unit next to me asked for some help. He was having a problem with the main trip that kept tripping. A 'sparks' had wired up his 9.7kw water heater via a new piece of 6mm , that went in to a switch, came out in 4, then hidden out of sight into 1.5 and into a 6amp trip. Hidden on top of one of the kitchen cupboards was the instructions, which said many helpful things including something about 45 amp breaker!!

Got called out to a house where: they were getting shock from shower while standing in the bath, the rcbo for kitchen circuit constantly tripped out, and some lights glowed a little even when switched off.

On investigating inside CU I found I had no voltage between L & E, although still had 240 between N & E and L & N. In the end I concluded that I had a live incoming earth (TNS supply)! Seemed to me this had to be the result of 2 faults on supply side - one to break the earth continuity back to sub-station, and one nearer the property to connect the live supply to earth - otherwise sub-station fuse would have blown.

I disconnected earth, put in earth rod an connected up as temporary TT, and told customer not to touch the earth until DNO had been as I couldn't think how I could disconnect it. Just glad I hadn't touched the earth as it was live back to sub-station fuse!

btw - DNO did find 2 faults - one each side of the front garden wall
