Explain why RCDs fitted into extension leads or incorporated into plugs are forbidden

Adam Seddon

this question is inside a mentor guide at the place i work for someone to be signed off as a fully competent electrician.

none of us can think of any reason why this may be the case, can anyone else?

    I do not think it is wise to deliberately put people at increased risk of a bad shock to prove a point that in someone else's opinion not RCD protecting a socket should have attracted more than a C3 whenever it was last inspected, That is what is being suggested.

    I don't quite follow. I'm not suggesting that 30mA RCD protection is omitted - just that where is it deemed necessary (according to local risk assessment - which may or may not align with codebreaker type guides), it could be seen as being better to provide it as part of the fixed installation rather than a portable device. (Less likely to be damaged, much easier to find & test every 3/6 months, can't be defeated by plugging in something else or using a different extension lead). This is all theoretical conjecture of course - we don't really know much about the OP's situation and whoever wrote the requirement might have had something quite different in mind.

    Safe to say I've seen much more "curious" stipulations in some H&S policies....
