Thx bernardgreen very interesting.

I thought and I'm only guessing here that the 'time' can only be measured when there is no power in the circuit hence a switch going from on to off. If everything is connected and the trip fires, but if there is still some current from items plugged in leaking into the circuit, then that would...

Hi Spark thx, will get him to test them in isolation on final visit. They definitely were not tested that way. circuits are lights, central heating, fridge, hob, shower, oven, ring main downstairs, ring upstairs, kitchen ring, outside lights. Oven, hob, ring, lights / shower ring, ch...

Top man EFLImpudence all makes sense to me and is more or less what the sparks said. My board is a 63a 30ma rcd and 63a 30ma rcd they did advise to maybe change one to an 80rcd and keep the other as 63rcd. I don't understand what that is about will have a read up. I do have the option to...

Thanks again EFLImpudence at least the Ze with the PFC is computing, so I guess I have nothing to worry about there - to a degree? 1 of the lighting circuits with the low ZS does have a bathroom so I think the rad in there has an earth to the lighting circuit - will check. Only bonding I know...

Thanks EFLImpudence soz for the length :-) Ok, for the prospective fault current is 0.506 lighting 1 is 1.30 zs and is about 26m in total lighting 2 is 0.42 zs and is 17m lighting 3 is 0.53 zs and is 16m All rcd times met 1 x IΔn (30mA) - maximum 300ms but only 3 met 5 x...

Hi all, great site I'm not a big DIY'er but looking to pick some brains - I'm after some advice as I don't have total confidence in the 4 sparkies I've currently used. That said I am not a sparky and if I'm being a total muppet please tell me - I can take it :-) Basically I bought an old...
