Alun TomApr 25, 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.

Crabtree 6HS16C Loadstar 16A MCB

RCD trip due to there being a difference in the current going out through the live and the lpadstar returning through the Neutral. Again thank you all for your help. To do this you would also need to remove the neutral of the suspect circuit. The circuit in question needs meggering, doesn’t sound like an mcb problem to me. May I thank loafstar all for you contributions to my query.

BazzaApr 26, You would spend more lucrative time just visually inspecting all your garden stuff. Share This Page Tweet.

Placed a light attachment to one of the sockets and all was well for some 5 or so hours. Its not, JP, they have special shrouded busbars and a single tab lock-in system unique crabtdee the Starbreaker. Thanks peter but no. As other poster said that aint the neutral bar it is the LIVE busbar. I have a Crabtree Loadstar cu that was installed some five years ago.


The ends of the supply wire temporarily terminated 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 This is after I toggled mcb switch a dozen times!

Alun Tom likes this. I was not thinking when writing thread sorry but thanks for highlighting it!! The cable runs are enclosed in plastic trunking so it should not be affected by vermin!!!!

Have you had any little furry visitors having a chew at the cable? Usually caused by some or all the current leaking to Earth due loasstar a short on either the live or Neutral conductors. Alun TomApr 26, Yes I have thought of it but discounted that as a cause!!

Hi spinlondon thanks cable fully enclosed.

Switch the circuit off, and inspect all the termination points at the different accessory positions. I will now get an expert in and see what can be found.

Symptoms are this Peter p There is a dedicated mcb for the garden The circuit was installed from new some 5 years ago.


Looks more like a Starbreaker db to me. Maybe the MCB has another circuit connected to it. You should find water problems in at least one of them.

OP have you tried to remove the breaker? 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!

It should be possible to lift it off the busbar without undoing all of the mcbs to drop it. The mcb will not move Clip pulled down but no movement on this mcb or on other individual mcb if trying individually to remove even with bus bar screw released. Agree it won’t is highly unlikely!

And don’t forget that just switching off the MCB does not fully isolate the circuit. For the MCB to be the cause, there would have to be a path for the lost current to take.

Thought it was the pump. Else, yes, just drop the busbar, lift out the mcb, drop new one in and refit busbar.
