Wiring to a shed.

[trialscot]

Hi,

I'm thinking of relocating our washing machine and tumble dryer to a shed in the garden.
What type of cable would be needed to be laid underground and would it need to be in conduit of some kind?.
A sparky would be wiring up, I'd just like to know the requirements.

Expect steel-wire armoured cable, dug in at least 18 inches (500mm). The sparky will sort out the size and number of wires in the cable. You should also expect a mini consumer unit at the shed end. What's at the house end will depend on where the connection is made and how easily it can be achieved, but ideally it would come from its own circuit breaker in the consumer unit. If you want to make a friend of the sparky and save a few pounds, offer to dig the trench yourself - we're good with screwdrivers, dislike shovels!!

As your going to have a water supply out to it then unless you use a plastic pipe to feed the shed, you will need to run a bonding conductor to it or make sure your CPC from the house would be large enough to do both Earth protection and bonding.

If your house is supplied by TNC-S then you will have to get your DNO permission to export the earth from the house, so may pay you to think about TT for the shed.

An adavantage of TT to the shed would be that your water supply if metal could be bonded locally.

As this is in the garden you need to notify this or get an electrician that is part of a self certifying scheme.

Bottom line is get the electrician in he will advise you and more than likely let you dig the trench, saving you a few pennies.

Not in Scotland you do not. Different rules apply.

After the recent cold weather, consider how you will stop the water supply freezing. The underground bit should be OK if dug in deep enough, but inside the shed....

Maybe add a small tubular heater or pipe trace heating and a frost stat to the electrical spec.

Getting leccy and water out to the shed will probably be trivial compared to getting a drain back from the shed.

And will Mrs Trialscot (I am making assumptions here) be happy wandering through the hoar frost with a basket of smalls three times a week?

Also I would be worried about water in the machine freezing. That could be expensive.
