Range cooker tripping RCD

[lost-sole]

Came across this problem at weekend brandnew range installed 40amp mcb on RCD side of split load board. Cooker isolator is 2 gang with socket out let. The rcd trips when ovens are on I know the reasons but was wandering how you go on with regs as all i could do was move mcb over to none rcd side of board so now you have a socket in a kitchen thats not got rcd protection do I

1. change cooker isolator to one gang without socket, don't think owner would be too happy as it would require backbox to be moved and some more tiling.

2. label socket outlet warning notice etc

3. Become a joiner!!!

as i remember you can supply a fixed piece of equipment from the non rcd side, and can you not label the socket as a non rcd protected socket??

I would be asking why a brand new cooker is tripping a RCD?

 

[tony.towa]

I agree with "the doc". I would understand it more if it were the hob tripping it out but not the ovens.

Whats the reason that the RCD trips, is it when the cooker switch is turned on or just when the oven is turned on.

as spark doctor says, im also unaware of common reasons for cookers tripping rcd's

it is a beast 3 ovens, i mean i had all 3 switched on so it must be the eliments doing it. as regarding supplying fixed equipment from non rcd side not sure if this is right on this occasion as portable equipment can be plugged into the socket outlet and trust me this guy is a solicitor and no common sense so you can bet your life he'll plug a garden chainsaw into it and chop through the cable or something

have you done an IR test on it?

i suppose techincally you could label it for one item of equipment, but what? "Kettle only", "electric can opener only"

Difficult one, i would be more tempted to try and sort out the problem, it shouldnt be tripping an RCD

hi, was called out to a sim fault.. customer said mfi had fitted the kitchen and oven and when the oven was switched on it would trip the rcd.

Found the oven wired in at the consumer unit on a 32A mcb on the rcd side but the nuetral was connected on the non rcd side! which would cause the rcd to trip when current would flow..

hope that helps? worth a look, easly done
