Enclosure for 30ma rcd

[ricky2609]

Been out to a property to price up repair on a couple of little bits with an old wylex board which has a 100ma RCD main switch. If I was to fit an upfront 30ma rcd before the main board would it have to be in a metal enclosure, haven't needed to do this before and not sure if enclosure would have to be metal or plastic

Thanks

If you were to fit one RCD to cover the whole installation then it would not be compliant.

I advised a board change would be better but as this is a rental property & landlord does not want to spend would it not be better to make it safer with a 30ma rcd first

It may be safer it terms of increased protection against shock, but may be less safe in the event of a fault due to a complete loss of power. That's why there are regulations to prevent the action you are considering.

There is no regulation which allows you to ignore the other regulations when your customer wants to do a job on the cheap.
If the customer won't pay for the job to be done properly then turn the job down.

No just looking for an option to make install safer before I do anything

What are you doing.

What are you doing.

replace some broken sockets & faulty cooker switch, moving a 240v fan out of zone 1 take down some old lights and replace with pendants

Some of that can be deemed maintenance but if you are moving the fan then additional rcd protection will be required, is it not suitable for use in zone 1.
