Garden Pond Pump installation.

[Robert B]

We are considering putting in a garden pond with a mains operated pump.

Is it legal to drill through the wall of the house and connect to a waterproof RCD box on the outside of the house. Use armoured cable in ducting running under the lawn, then connect up the pump.

Two connection ideas.
1 use a normal plug top in the house
2 get it done as a spur off the ring main. (Would have to be a professional installation).

The pump would be about 50w.

Please can some point me in the correct safe direction.

Cheers.

personally i'd get an electrician to install an outside double socket within reach of the pump flex. if there's no RCD on the house socket circuit, then the outside socket must be an RCD type. then you can plug in the pond pump and also have a spare outlet for garden tools. how far from the house is the planned pond?

Thanks Telectrix

The pump will be about 10m from the house wall.
All floors are solid wood so one can not get underneath to run a cable easily. The nearest wall is a flat roofed extension so the only way to get a cable from the fuse box would be for it to be clipped on the outside, unsightly, also there is no space MCB blanks in the fuse box. Hence the spur/plug idea.
Prefer the spur through the wall, professional instal if legal.

you can spur 1 single or 1 double socket outlet from a socket on the ring, as long as the existing socket is not, itself, a spur.
