Curious fault in double socket

[Maurice Pennance]

Hi, There's this double socket in the tack room of an old stables. It's fed individually direct from the CU in the workshop next door. There is nothing else on this circuit although another radial is wired into the same 16A breaker which feeds another double socket in the storeroom next to the tack room. The tack room socket started tripping the RCD whenever put under load. At first I though an appliance fault until I tried a lamp, a drill, and an angle grinder all of which tripped the RCD when plugged into the tack room socket and all of which work fine when plugged in elsewhere. So I powered down and took the socket apart finding no visible fault in the wiring or connections, everything tight, no insulation damage etc. So then I replaced the socket thinking well maybe that's faulty, but no, same thing happened. So what might be the possible causes of such a fault? Earth leakage across the whole system? Any suggestions as to what possible causes of this fault might be? Thanks in advance.

It could be anything.
Impossible to diagnose from my iPad.

Wow are they that good?

There are many faults which could be occurring...we need more information...Does the RCD trip during the dark? ... Do they keep pregnant horses,in the stable?

It could be a nightmare...

Pregnant horses!?

Pregnant horses!?

He either means pregnant pauses, or horses in foal.

That wasn't lost on me Peg !!

Pregnant horse after 6pm would be a night-mare?

More than likely a failed flux capacitor in the DB?

Ring a sparky. I doubt they’d charge more than a... pony?!

You’ll have “neigh” chance of getting any sense out of this lot. Too busy “horsing” around.
In fact, I think they may be “unstable”

N-E fault... only shows up when using current. Has anybody worked on the db recently and maybe replaced the neutral in the wrong bar?

 

[Maurice Pennance]

A sparky with test equipment will be able to find the issue quickly and relatively inexpensively.

I'd just be guessing trying to diagnose over the tinterwebs

Saddled with this annoying fault I galloped round to the CU in the workshop and swished the tails. Someone had been horsing round in this CU and placed the neutral in the wrong paddock thereby unbalancing the CU and throwing any rider off at the first hurdle. Fed the CU some Epsom salts and went to the Horse and Hounds to make hay while the sun shines.

Horse nibbling at the cable?
