garage lighting & socket circuits inc outside sockets design opinions appreciated

[paps1976]

Hi, following the success of my last post.

I now wish to layout a drawing of my garage prior to wiring it.

I have a 5 way consumer unit fed by 6mm swa. The cu has a 63amp 30ma rcd.

My plan is to-

1.- A 1mm2 T+E lighting circuit, incorporating 4 x 5' twin flourescent fittings + 1 x4' single flourescent fitting, all on a 6amp MCB
2.- A 2.5mm2 T+E Radial circuit with 6 double sockets on it, on a 16amp MCB
3.- Security lighting flood lights seperate circuit to lighting circuit on a 6amp MCB
4.- A Garden feed in the form of a 6mm SWA (already in underground) to decking to run 2 double sockets, on a 16amp MCB (one of the sockets will run a small swimming pool heater)
5.- A spare way

Is there anything garingly obvious about this design that will be incorrect to regulations Ie is the 1mm2 T+E adequate?.

My theory is to split up the circuits to keep it simple.

I wont be using the garage for anything industrial size ie an oil welder, it is just used for hobby work. The existing 1 double socket in the garage is presently run of a fused spur and i have never blown the fuse.

Any advice will be greatly appreciated.

Outdoor power??

Actually fitting 2 x 6mm SWA could be tricky into the average IP rated socket.

You need to do your cable calcs to be sure the 1mm cable is adequate. I can't see any reason why it wouldn't be though. Your job description sounds good!

Double your running current for start up on fluorescents? or am I imagining this?

What is this swimming pool heater and what is the swimming pool

Hi LABCC? I'm not what the abbreviation is, new to all this forum stuff.

Hi it's a large double, but with all of the racking and shelving i have for storage i wanted to light up really well to all the edges. I always get really frustrated when you get all the shadows when you are working.

I will be switching the lighting seperately also so i can light up just an area ie around the work bench etc.

Hi the pool is a 10' round put me up, i will have to check the heater wattage i'm not sure. It isnt anything special thought just one you can get with all of these types of pools.

Hi thanks, i will check and do all my calculations. Is there a recommended tolerance to work too ie 25% overcapacity?

You'll be very lucky to get 2 X 6mm cables into the accessory terminals without cutting strands out, which basically defeats the object of running in a 6mm cable..lol!!!

LABC = Local Area Building Control. Your planned works includes installations that come under Part P of the Building Regulations - but you knew this didn't you??
