Installing a light in a shed.

[GrahamUK33]

I am having difficulty reading the wiring circuit diagram to wire a light socket. I just want one double socket at the door to turn on and off two lights independently.

I have twin and earth (brown - live, blue - neutral, and copper - earth) coming from the house and twin and earth coming from the light.

I have a double 2-way socket which I suppose I need to wire it as a 1-way. I have two terminals with L1, Com and L2. I’m puzzled as to where the cables need to go.

So what you have is two pairs of twin and earth cable and a two gang switch plate?
Are there two lights that operate independently?
are you just swapping old for new switches?
or is this a new circuit?

 

[GrahamUK33]

This is a new circuit.

Twin and earth coming in from the house.

Both following light are independent.
Twin and earth coming from a fluorescent light inside the shed.
Twin and earth coming from a light attached to the outside of the shed.

Both lights to be operated via a double socket (2-way double socket).

You really should learn the difference between a socket and a switch.

Join the neutrals, join the earths. Connect the line supply from the house to one of the COM terminals on the switch, and then run a short strapper to the other. Connect the line to the lights to the L1 for each switch. Done.

Thats great, many thanks.

Are you aware that T&E is not suitable for the outdoor environment.
Or is it protected?

 

[GrahamUK33]

I will be using the 2.5mm twin and earth in a duct to protect it, I will be then putting some sealant each end to stop muck and damp getting in there.

I'm afraid that you still may not install T&E in that manner... a cable buried underground should have an earthed metallic armouring or sheath

Looks like it is going to be a trip to Wickes/B&Q.

 

[PrenticeBoyofDerry]

Who designed the circuit, what factors were taken in to considerations?
What distance is the shed to the CU that is supplying the power, cable size, protective device rating, has voltage drop been calculated, measurements for R1+R2, IR, polarity, is there RCD protection, have building controls been informed?

He has the info he needs - he wont be back to hear its unsafe - as long as it works!

He might not be back if it doesn't work either, sounds like the op has not carried the correct procedures to assure the installation is safe!
Some crazy people about!

Crazy?

Or just extremely ignorant?

When our garage was wired up for a socket and a light the 6mm cable was fed through a flexible plastic(?) tube concreted into the patio before diving 2ft underground where it was laid on top of gravel then cheap flag stones cut in half were laid on top of the tubing before the soil was filled back in - apparently that complies with regulations

There are incompetent, thieving, lying, cowboy electricians just as there are ditto builders, plumbers etc.

You got one of them.
