If it does not trip, the fault is with the wiring. Usually caused by crabgree or all the current leaking to Earth due to a short on either the live or Neutral conductors. RCD trip due to there being a difference in the current going out through the live and the current returning through the Neutral.
Yes I think I was barking up the wrong tree with my mcb hard fault! Hi spinlondon thanks cable fully enclosed. Alun Tom and unphased like this.
Today checked again and this time mcb did not trip rcd when switched back on. As other poster said that aint the neutral bar it is the LIVE busbar. Yes my fault re polarity of bus bar!! Rcd still tripped immediately whenever mcb was switched on. Thought it was the pump.
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.
Switch the circuit off, and inspect all the termination points at the different accessory positions. Alun TomApr 25, I have a Crabtree Loadstar cu that was installed some five years ago. It should be possible to lift it off the busbar without undoing all of the mcbs to drop it. Perhaps the UV got to it? Again thank you all for your help. I was not thinking when writing thread sorry but thanks for highlighting it!!
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!

Yes I have thought of it but discounted that as a cause!! There is no issue re moisture as this is all in the dry As mcb Has anyone seen this typ3 of thing before? Yes, my password is: Now only the 2. Agree it won’t is highly unlikely! Not likely to be mcb at fault.
Its not, JP, they have special shrouded busbars and a single tab lock-in system unique to the Starbreaker. Unusual for an MCB to fail, are you sure its not overloaded. Do loadsar already have an account? The screw loadstqr already loose.
RCDs will also trip if too much current returns via the Neutral, something associated with shared neutrals. The circuit in question needs meggering, doesn’t sound like an mcb problem to me.
Your name or email address: Have you had any little furry visitors having a chew at the cable? OP have you tried to remove the breaker? 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.
Disconnected both sockets from junction box. Thanks peter crabfree no. Maybe the MCB has another circuit connected to it. I will now loadsttar an expert in and see what can be found. Yes odd I know!

The mcb ceabtree 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. 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 crabbtree down the back release ring on the mcb etc.
