Hi. I plan to run an armoured cable from a plug socket in the house to a greenhouse:-
RCD plug + cable to IP56 junction box on outside of wall;
armour cable underground to IP56 junction box in greenhouse;
junction box in greenhouse will be connecetd to a) IP56 twin socket
b) IP56 one way switch to IP56 junction box to outside lights (junction box and lights transformer to be placed in an IP56 weather proof box).
The distance is about 20m. I will use the plug sockets for anti frost heater/hedge cutter/lawnmower. I realise that at any 1 time I can only use up to 13a.
I believe I can do all of this myself because it will mainly involve various connecting of wires. As I'm using IP56 throughout and as it goes into an RCD protected socket in the house, I believe I meet all requirements. But..
I read here that a 1.5mm 3 core cable will allow for 15amps, and 3,600watts. But as the cable will be 20m long would 2.5mm be a better bet? Don't mind paying the extra, just didn't want to stop everything working as a result. The trench is dug, and B&Q has 10% off until 4pm today! Thanks.
