Wiring a summer house

Question

I am looking to put a summer house in the garden I already have an armoured cable which is running to the garden shed at the bottom of the garden which powers a light and 1 x double socket.
The summer house will sit between the house and the Garden shed

My question would be I would like to put in 3 double sockets into the summer house could I put a junction box within the armoured cable that runs to the garden shed and feed electric into the summer house and then connecting all 3 sockets in sequence.
Is this a safe method.

The best solution is to divert the armoured cable into the summer house, install a small consumer unit, and distribute power to the summer house and the light and socket already in existence.

Hi, to add more socket into your shed we have to check the size of the cable, the minimum required is 4mm cable, lower than that we have to add some extra protection(RCD or RCBO).

Gareth · Answer

Hey Darren. Simply put yes, you can add the sockets, but as already mentioned by others - you'll need to consider the size of the existing cable and how its protected.  It might mean you have to include additional protection where you 'split' the cable to power both the shed, and the summer house. Also if it turns out the supply to your shed is too small, but dont want a larger cable, it might just mean you will be limited on the amount of power you can use in the summer house (eg lights etc) as opposed to powering a heater or something else of that nature. Ideally some pictures would be helpful so we can help you further.

You will need to consider whether the armoured cable is big enough to take the new summer house loading and whether the swa is protected by a rcd/rcbo, for three double sockets and a couple of lights I would suggest that the swa be 6mm depending on the length of the swa. Also you need to consider the depth of the swa etc. 
Always best to get a sparky to have a look .

this is absolutely not a safe method.   you need to get an electrician in..

Sammy · Answer

Hi there, yes you would be able to do that. But it all depends on what you will be plugging in to the sockets whether it can hold the amps. As if you are using 3 sockets with things plugged in it all depends on how much amps you are running through the plugged in items as it might exceed the amount of the breaker at the fuseboard which will mean it will trip out.

Hello 
Yea its safe so far you use waterproof junction box and proper gland

Stephen · Answer

There are several factors here to be taken into account, for example, CSA of cable, load, length of cable run, RCD-MCB protection, IP rating to name a few.

Joe · Answer

Hi Darren,
The answer to your question depends upon the size of  CSA (cross-sectional area) of the conductors in the cable, which is currently a use.
Also dependent on the cable route and condition of the cable also take into consideration that the circuit breaker should be Rated for no more current than the cable is rated.
