Discuss Sanity check - replacing MCBs with RCBOs in the UK Electrical Forum area at ElectriciansForums.net
Hi All
Wanted to get feedback on this idea.
I have 3 fuse boards which trip frequently whenever there is a lightening storm nearby. My electrician friend has suggested he swaps all the MCB's with RCBO's so that individual circuits trip rather than the whole board. Each board currently has a main RCB for protection - the proposal is to replace it with a 63A MCB.
1. Is this a good idea? I can't see a downside other than cost.
2. Any other thoughts on how to stop these boards tripping everytime there is a burst of lightening nearby?
Thanks!
Hi Tony
Do you mind to expand on that?
Thanks
In the UK??
Rain getting into an outside light fitting?
Unless it’s a DP MCB it’s a dumb idea.
What testing did you’re “electrician friend” carry out before recommending replacing the existing MCB’s with expensive RCBO’s. Which if SP provide less protection than you have now. Only very expensive DP or SPSN RCBO’s give real protection.
I don’t believe your “electrician friend” exists.
A photograph of this set up would help.
I'm sorry but the proposed method of "solving" this problem is ridiculous, you've already found the cause of the tripping on one board and you're not an electrician so how come your "electrician friend" couldn't locate it?
Get someone in who knows what they are doing and so will be able to find the reason for the other boards tripping and come up with a sensible, cost effective method of resolution. If you're determined to throw good money away I'll come over with my test gear as long as you are prepared to pay the exorbitant fees for travel accommodation and subsistence as well as my very reasonable fee for my professional services.
