Outdoor wiring

A_Clock

Ive just got a water feature, but the cable isnt long enough for where i want to put it Im going to have to put an extension onto it, but not sure how i would stop water getting into it Would i have to use a special type of wire? because the sun would surely damage just a plain one after awhile...

I am really confussed about the safest and best way to do it :eek:

Is it mains or low voltage ( ie via a transformer that is plugged into the mains ) ?

Unless you are confident all of the cabling is low voltage then this really sounds like a job for a professional electrician. Mains electrical equipment outside is subject to specific regulations and a DIY installation could put you and your family at risk for more than one reason.

Make sure you ask your electrician for proof they are working to the 17th Edition (BS7671) and are a member of an approved body such as the NICEIC. They will be only too happy to offer some advice and a written quote if they are good tradesmen

Standard PVC cable does degrade in the sun after a while. Butyl rubber cable is used for outdoor wiring and should be the type already used on the pump. Rubber cable is marked H05RR-F compared to H05VV-F for the same thickness PVC insulated cable (medium light weight insulation).

There are waterproof cable junction boxes available but they are best avoided if possible when using mains voltage. A plug-in RCD circuit breaker should be used in the mains supply socket.
