I will now loxdstar an expert in and see what can be found. Alun TomApr 26, May I thank you all for you contributions to my query.

If it does not trip, the fault is with the wiring. Disconnected both sockets from junction box. Does not see daylight! New cable through house to a junction box situated under cover in dry position supplying two power points to ip67 on house wall One power point supplying small pump Last week rcd tripped.

It should be possible to lift it off the busbar without undoing all of the mcbs to drop it.

Do you already have an account? Alun TomApr 25, Today checked again and this time mcb did not trip rcd when poadstar back on.


OP have you tried to remove the breaker? Again thank you all for your help.

It is a Loadstar. Hi spinlondon thanks cable fully enclosed. Rcd still tripped immediately whenever mcb was switched on.

Maybe the MCB has another circuit connected to it. Thanks peter but no. There is no issue re moisture as this is all in the dry As mcb Has anyone seen this typ3 of thing before?

Usually caused by some or all the current leaking to Earth due to a short on either the live or Neutral conductors. Yes odd I know! RCDs will also trip if too much current returns via the Neutral, something associated with shared neutrals.

Switched off mcb for garden and switch on rcd all ok until mcb switched back on again! Have you had any little furry visitors having a chew at the cable? The ends of the supply wire temporarily loadztar by a choc box connector At present still tripping in that state but yesterday when reconnected to the socket worked for approximately 6 hours without tripping anything then mid evening Perhaps the UV got to it?

Else, yes, just drop the busbar, lift out the mcb, drop new one in and refit busbar. I have a Crabtree Loadstar cu that was installed some five years ago. Yes I have thought of it but discounted craabtree as a cause!!


Thought it was the pump. You should find water problems in at least one of them.

Your name or email address: It probably easier if you take the bus bar out but when you put it back make sure none of the clamps miss the prong and just tighten up on themselves.

No, create an account now. Now only the 2. The screw is already loose. Looks more like a Starbreaker db to crabtfee.

Yes I think I was barking up the wrong tree with my mcb hard fault! As other poster said that aint the neutral bar it is the LIVE busbar. Not likely to be mcb at fault. This is after I toggled mcb switch a dozen times! Alun Tom and unphased like this. Alun Tom likes this.
