i want to put a new 2 way con/unit in my conservatory to feed sockets and lights (very big conservatory) but what size cable can i run 6mm? its only havin a 32amp for sockets and 16 for lights thanx

go with 10mm and a 50A breaker in the existing CU

and 16A is a bit high for lights

in the old con/unit put a 50amp breaker in run 10mm from that into the new con/unit put sockets on 32amp? and lights on ???? 6anp are 10amp

use 50A (if you CU can take it) on existing CU using 10mm cable to the new CU. 32A for sockets and 6A for lights

you could use a small breaker in existing CU and smaller cable if you wanted

if there where no room in the old cu what would u do cheers

use a henly block to split the tails. 1 to the existing CU and the other to a small enclosure with the breaker for the cable to the conservatory

seems excessive ammount of work just to power the consevatory. If used for lighting and light power i would come of an existing circuit and downrate the lighting using a spur.

Echo delmel. I can recall a couple of similar topics recently.

Before you start running sub mains I'd consider if its possible to split into your existing ring main. You can then spur the lights behind a 5A FCU.

Keywords

Conservatory, RCD, extending ring.

If you want more advice it would be helpful to know what circuits you already have, their arrangement and what you want to add.

Key ring limits are area it covers, volt drop and disconnection times. Also RCD protection is needed for sockets likely to supply outside equipment.

Also :-
50A is a 10mm+ sub main.
16a is in theory allowable for a lighting circuit but it puts major limits on the types of fittings and switches. 10A is the practical max, 6A the norm.

Yup, I mirror the last two posts.

OR, you could simply run a 32amp 4mm radial from the CU, and FCU the lights.
