I know 100ma is not sensitive enough to protect from shock but could I fit a 100ma RCD unit on the incomer and then retro fit combination 30ma RCDs and mcbs to the relevant circuits (sockets) in the Proteus CU?

Ok I will contact my supplier who is British gas (so I guess i will have to pay) :? Seeboard are the LEC. I could retro fit a 100ma RCD (i.e. swap out the 30ma unit) but I would have to remove the supplier fuse to do this. Am I allowed to do that?

Thanks for your quick response guys... If i get a suppliers earth how will this solve my RCD tripping problem? The inference you suggest is that the RCD is required for the whole installation because I have not got a proper earth? Is this correct? In this case (if the above is correct)...

Sorry for the delay... The cable you refer to is an earth cable and is joined by a connector block as the first photo shows. This does go to the CU through a white trunking. There is another earth that I can trace to the outside of the garage which then comes through the garage floor into...

The rcd is a 2 pole 63A, 30ma unit feeding a 100A mcb board. I am not in a rural area as such but we are on the end of a vulnerable network. Lightning and power cuts have taken out the RCD in the past. I do not know why one RCD is protecting the whole house but I just had a look and...

I have a current fault of a cooker that trips my RCD. The trip may not come immediately on turning the cooker supply on but it will normally trip after a given amount of time. For example the trip may occur when I turn the oven on or after a few minutes with no action or change occurring (no...
