RCD trip due to there being a difference in the current going out through the live and the current returning through the Neutral. OP have you tried to remove the breaker?

Yes lowdstar fault re polarity of bus bar!! Have you had any little furry visitors having a chew at the crabtres 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! As other poster said that aint the neutral bar it is the LIVE busbar.

Perhaps the UV got to it? Symptoms are this Peter p There is a dedicated mcb for the garden The circuit was installed from new some 5 years ago. You must log in or sign up to reply here.

Alun Tom and unphased like this. I am glad you corrected me on that issue! Usually caused by some or all the current leaking to Earth due to a short on either the live or Neutral conductors. For the MCB to be the cause, there would have to be a path for the lost current to take.

You should find water problems in at least one of them. Maybe the MCB has another circuit connected to it.

Yes I think I was barking up the wrong tree with my mcb hard fault! No, create an account now.

It is a Loadstar. I have a Crabtree Loadstar cu that was installed some five years ago.

Thought it was the pump. Now only the 2.

I am still intrigued as to why it is knocking off the RCB as absolutely nothing has touched the cable and the run from the cu to the the adjoining shed is all indoors. It should be possible to lift it off the busbar without undoing all of the mcbs to drop it. Share This Page Tweet.

Yes I have thought of it but discounted that as a cause!! Thanks peter but no.

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

Hi spinlondon thanks cable fully enclosed. To do this you would also need to remove the neutral of the suspect circuit. Agree it won’t is highly unlikely! The circuit loadstra question needs meggering, doesn’t sound like an mcb problem to me. Alun TomApr 26, Today checked again and this time mcb did not trip rcd when switched back on.

Yes odd I know! Your name or email address: I will now get an expert in and see what can be found. I now need to replace a suspect mcb Looking at the cfabtree of the cabtree 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.
