Sanity check - replacing MCBs with RCBOs

[drjarmin]

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!

Get another electrician before you get robbed blind.

Hi Tony

Do you mind to expand on that?

Thanks

What actually trips, the fuses or the RCD switches?

 

[drjarmin]

Always the RCD. There is one per board. Can trip as often as 20 times in a night if there is a heavy thunderstorm.

and how often does this occur?

and how often does this occur?

This year probably 20-25 times so far.

i'd be getting a competent electrician to test the RCDs.
