Outhouse Feed

blaband · May 10, 2011

I am having my outhouse rebuilt to become an enclosed porch, which is attached to the house. The original was fed by a 'mickey mouse' piece of t&e. When the rebuild is finished I want to install lighting and a couple of sockets. Would it be advisable to use a 'garage' consumer unit in the porch and run the lighting/sockets from that, rather than run a number of cables from the house consumer unit, through the house wall in

to the porch. What size of cable should I use if I choose to do it this way?

without more info, it's hard to advise. think though it would be easier and cheaper to extend the ring final ( socket ) circuit for sockets, and extend the lighting for the light/s. bear in mind the requirements of 17th ED. i.e RCD protection.

If you install a 'garage CU' you will still need to get a supply back to the intake...rather pointless.
As above....it sounds like extending existing circuits would be appropriate.

Thank's for that fella's. Much appreciated.

note however regarding the sockets you want to install. if you are spurring off a ring final ( just using 1x 2.5mm cable, then as there are more than 1 added sockets, you must fit a13A FCU at the point where you spur off

Thank's telectrix. Would it be feasible to 'break into' the socket ring main using connection boxes and extend that way?

better to come from a socket, then the connections are accessible . if breaking in to a cable, you need to either fit a 30A JB ( accessible ) or wagos in an enclosure . obviously safe isolation and working, blah, blah are essential..do not under any circumstances bung it in a choc block under ther floor.
