Domestic Fuse Box Replacement - RCD Per Circuit

[john storrie]

Hi all,

I am in the Maidenhead area and want to understand as a customer how much it would cost to do the following work:

Replace 15 way domestic split load mains box with one that has an RCBO breaker per circuit rather than the current RCBO managing several circuits.

The box was installed in October 2012 and I understand would need to be installed to the latest Part P specifications.

I would be looking to have this work completed by end of November if possible.

Regards John

I agree with the statement that if your rcd is tripping putting on rcbos isn't going to help as that circuit will still trip a blown light bulb should jot cause the rcd to trip. It's a good upgrade yes but your if your current system works why change it? The board in my house was installed in 1988 and is protected by a separate rcd which I tested last year and is fully functioning, if it isn't broke don't fix it.

I would be testing the back ground leakage before doing anything !

If a blowing bulb trips a RCD, there's a neutral to earth leakage fault present.
As said in several posts above, it's the underlying faults that need sorting, not the whole box reconfiguring.

^^ disagree.

I have seen a broken SL tripping a rcd
