30mA RCD requirement?

[HappyHippyDad]

Evening all..

I have just been to quote for a bathroom extractor fan and a kitchen extractor fan. I was pretty sure I understood the RCD requirements but it gets a bit confusing sometimes!

The bathroom extractor will probably be 230V (could be ELV though) and all cables will be in trunking in the bathroom. Even though in trunking I think it still needs to be RCD protected as per Regulation 701.413.3.3, although that reg does specifically state 'Low' voltage so would ELV still require 30mA RCD protection? The fan will be outside of all zones.

The cable for the kitchen extractor fan will all be run in surface mounted trunking, so I dont think it has to be 30mA RCD protected?

It is a TT, has 100mA RCD and all bonding is in place and adequate.

I've checked through a good few threads but theres some conflicting ideas!

Cheers..

Good point and since it's an older install I won't argue that their will be an increased likelihood of nuisance tripping.

Actually think there is regs against one 30ma rcd protecting the whole install. My bad.

I don't like these old 3036 consumer units, make's everything more difficult. =)

I would defiantly recommend to the customer that they should upgrade the consumer unit. Especially if they have any more add-on's in mind for the future. A better option in the long run.
