Consumer unit running from spur for pond stuff

[jonboy79]

Hi all,

So i was thinking about running a consumer unit from a spur for all the outdoor pond stuff. I wanted to have in there 3 Rcbo's at 6 amp, 1 for the pump, 1 for the led lighting and another for a water feature. None of these go past the 6 amps. They will only be used for this and nothing else, and wanted them to be protected and isolated with there own tripper, so say the lights go, the pump won't etc. The CU has about 10 feet to where i will be picking up the power. Will this be ok??

Many thanks

PS was going to run, spur > RCD > extension lead. But couldn't find anything that would be a mcb, unless you know of anything like a plug in rcd which is a mcb. I know the CU option is not the cheapest way, but also gives me a little project on the way..

Where exactly are you spurring from? Also this is notifiable work.

Thanks for the quick reply. From the ring that does the down stairs plugs i assume, it is a plug next to the down stairs toilets. I guess it's notifiable due to it being a outside circuit, but would a extension lead permanently fixed also be notifiable??

would a RCD plug in adaptor, plugged into your ring, which has an extension lead plugged in that, which would be protected by a 13A fuse not be acceptable? (that is a question aimed at someone who will correct me) do you know the current requirements of what you intend to power?

Yeah this was my standard option but like the idea of a mcb, as a rcd protects for earth leakage but would like something that protects the circuits of the water feature as it's got a pump and also some led circuitry lighting, and can't get into it if it goes wrong.
Cheers

ps will a low amp fuse be just as good?

Ordinary 3A plugtop fuses would probably do.

By the way, is your socket circuit already protected by an RCD in the consumer unit or elsewhere?

1362 fuses and 60898 MCB's are both over-current protective devices. They operate under the same conditions and are there for the same reasons.

Cool thanks so a fuse will be just as good.
