It is a Loadstar.

Alun Mmcb and unphased like this. TBH I think you are better getting someone in for this. Hi spinlondon thanks cable fully enclosed. 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.

Perhaps the UV got to it? Do you already have an account? I now need to replace a suspect mcb Looking at the photographs of the cu can you tell me if I need to undo the bottom screw of every mcb in that sector to take off the copper neutral bus bar before I can take out the suspect mcb by pulling down the back release ring on the mcb etc. Yes I have thought of it but discounted that as a cause!! 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 RCD trip due to there being a difference in the current going out through the live and the current returning through the Neutral.


Maybe the MCB has another circuit connected to it. Thanks peter but no.

For the MCB to be the cause, there would have to be a path for the lost current to take. Now only the 2. The screw is already loose. I am glad you corrected me on that issue! Have you had any little furry visitors having a chew at the cable? Rcd still tripped immediately whenever mcb was switched cfabtree.

Looks more like a Starbreaker db to me. As other poster said that aint the neutral bar it is the LIVE busbar. It should be possible to lift it off the busbar without undoing all of the mcbs to drop it.

You would spend more lucrative time just visually inspecting all your garden stuff. Not likely to be mcb at fault. Again thank you crabteee for your help. I was not thinking when writing thread sorry but thanks for highlighting it!!

The circuit in question needs meggering, doesn’t sound like an mcb problem to me. There is no issue re moisture as this is all in the dry As mcb Has anyone seen this typ3 of thing before?

I have a Crabtree Loadstar cu that was installed some five years ago. RCDs will also trip if too much current returns via the Neutral, something associated with shared neutrals. 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.

Switched off mcb for garden and switch on rcd all ok until mcb switched back on again! You must log in or sign up to reply here. Alun TomApr 25, Yes, my password is: I will now get an expert in and see what can be found.

This is after I toggled mcb switch a dozen times! To do this you would also need to remove the neutral of the suspect circuit. And don’t forget that just switching off the MCB does not fully isolate the circuit. Yes odd I know! Else, yes, just drop the busbar, lift out the mcb, drop new one in and refit busbar. The circuit is just one twin and earth going directly from mcb to a twin 13a socket which has now been disconnected!

I am still intrigued as to why it is knocking off the RCB as absolutely lloadstar has touched the cable and the run from the cu to the the adjoining shed is all indoors. Does not see daylight! Switch the circuit off, and inspect all the termination points at the different accessory positions. If it does not trip, the fault is with the wiring. Today checked again and this time mcb did not trip rcd when switched back on.

You should find water problems in at least one of them.

Alun Tom likes this. No, create an account now. The ladstar runs are enclosed in plastic trunking so it should not be affected by vermin!!!! It probably easier if you take the bus bar out but when you put loadsar back make sure none of the clamps miss the prong and just tighten up on themselves.

Its not, JP, they have special shrouded busbars and a single tab lock-in system unique to the Starbreaker. Disconnected both sockets from junction box.
