hello, got a job needs a supply outside to a log cabin for a hot tub, two socket outlets and one light.

what i was thinking of doing was running 10mm 3 core armoured.

i was goin to install a ccu next to original with a 30ma rdc. split the tails, henley block.

run the armoured 600mm underground 15m max, and once in the log cabin gland off and put another 3 way consumer unit again with 30mA protection.

then in t&e 1.5 wire a swich and light

in 2.5 t&e put two sockets in.

and off the same board wire in the hot tub.

will 10mm 3 core armoured over 15m be ok?

cheers guys!

havent done much armoured. if you know a better way, step by step it thankyou!

advise much appreciated!!

Funny man Lmao! 50a breaker as cable at 10mm will be rated to approx 51/52a it's just good to see what other people come out with, so please don't try mug me off! Polite warning, thanks

I think you will find 10mm is rated at 60 amps buried in the ground and clipped direct is 67 amps for armoured

Many apologies, my copy of BS7671:2008 says different, but I'm sure in your edition you are quite right. Good luck!

That's good thought I owned a duff copy there for a bit. But it seems he can't back up his claims can not be backed up. Strange that. Lol

It's both the client and the general reputation of us 'sparks' that I worry about. Any fool can terminate cable, not too many know what they are actually doing or indeed doing it safely
