Power to sectional concrete shed

Question

I want to run power to my sectional concrete shed for lighting and sockets. Would I need to have the building insulated/lined with plywood first?

Hi, I wouldn’t say you need to make any major  alterations to the inside of your garage to accommodate power for lights/sockets. Could install small dwangs/battens of wood for mounting sockets etc and plastic conduit could be run and fixed to the concrete for the running of cables etc.

Hi no you could have it surface conduit installed for all circuits and a local surface consumer unit. You would also require an earth rod to supply the earth to said structure.

Hi, 

The quick answer is no you don’t need too as long as it’s water tight. 

If you want it to look nice then yeah insulating and ply is the way to go.

Hope this helps

That depends on what you are using the shed for it wouldn't hurt but you don't need to just to run power to it

Hi that’s a really interesting question , by insulation the concrete shed I’m assuming your considering the external influences that the new electrical equipment will be placed in. 
In my opinion any qualified electrician would really consider what sort of environment the accessory’s / equipment is going to be placed in. 
So firstly we need to consider what the use of the outbuilding is going to be for. Ie are you intending to run and power tools in the building or are you just looking at basic lighting and some power outlets.   
Next we need to consider what are the potential hazards that could damage the electrical equipment? Ie water , heat ect. 
From here we should select suitable accessory’s, we would consider what IP rating they will be required to be. Do they need to be more robust material such as metal so they don’t get damaged?

Hope I’ve not complicated things for you. 

Ps you will also need to consider what type of supply cable you will use ie swa clipped direct or ducting ?
It really depends on the general layout of your garden (the route) . 
Best of luck with it !

It would be possible to run a supply and add lighting and sockets to the shed without having it insulated or boarded out. However, it would certainly be much easier to install the electrical components with boarding in place to fix to, plus, it would be difficult to add the boarding and insulation at a later stage if you did the electrical work first. 
An ideal scenario would be do the jobs in conjunction with one another, as that would actually allow you to hide the cabling behind the boards for a neater finish.

Christopher · Answer

If you line it first depends on the amount between the lining and the shed it'd self you could use a plasterboard backbox however the cable would need to be run first before the lining is installed

Hi there, you don’t need the building insulating, you would have to use armoured cable to the concrete shed and then run your electric cables through conduit in the shed and have it’s own separate consumer unit to protect the installation.

No matter where you want to install an electrical installation you must follow the current bs 7671
Wiring regulations will tell you the method and type of wiring and accessories 
But the most important thing is a qualified electrician must by law Carry out the work and notify the building control

Adam · Answer

Not really, you may surface mount all electrical sockets and outlets with PVC conduit or trunking. If that's what you mean?
