Garden Shed Electrics

[EricBotty]

Hi

I'm looking at installing a shed with general lighting and a power source for a mitre saw and garden equipment battery charging. Does anyone have any ideas where to start?

How deep does the channel have to be to carry the cable and does it require special trunking?

What sort of protection is required, within the shed and at the fuse board.

All help would be gratefully appreciated

the work is notifiable to building control under part "P" before commencement it must be up to standard and will be checked at your expense
its often cheap to get a part p electrician you do the donkey work to his instruction then he installs and passes the work

the other option is an extension lead with a plug and socket not fixed this is not notifiable as you unplug and roll it up when finished

In the main there is a huge jump in what is required as one goes over 13A. Above 13A likely it will need dedicated circuit from consumer unit so would be notifiable even after 6th of April so really if over 13A then it's a get a scheme member electrician.

Under the 13A threshold then fused connection units (FCU) can be used for the origin of the supply and also using a switched FCU as the light switch in the shed no real need for a mini consumer unit in shed.

Cable must be protected and normally that means steel wired armoured (SWA) depth is really a case of common sense for example under the paving stones it really only needs warning tape two inches is enough but in garden or even lawn spades and forks will be used even if only to aerate lawn so needs to be much deeper. Following fence line can keep cable out of harms way.

RCD protection can be added if not already there at either house or shed side using a RCD FCU is common method. Since you will likely not have test gear I would say use an active type.

So job one is work out what you need. If you want electric heating then FCU method is out. But few odd power tools and lights likely not a problem.
