Radial or RFC for Summer house

[TiffyMike]

Hi. I will soon be wiring up my summer house. My plan is to run 10mm2 SWA from spare 50A breaker on my house consumer unit (approx 20m) to a 40A garage consumer unit with 6A MCB for 1.5mm2 lighting circuit and 32A for 2.5mm2 RFC. I plan to have 5 double sockets which will have heater, TV and console, Bluetooth speaker, phone chargers etc and the occasional lawnmower plugged in.
My question is are my plans ok or would I be better with a radial circuit?

Thanks again pc1966. That’s the cable I intend to buy, glad you recommend. Sounds like good advice, I will look at using 1mm instead of 1.5mm for the lighting.

One final point of note is to use decent glands for your SWA cable, and to have a flying lead for making sure it is properly bonded to the earth.

If affordable, I would use this sort of thing:

STORM® TAURAS M20 Cable Gland (Pack of 2)

Ingress protection [IP68] and faster- fitting over conventional armoured cable glands

www.cef.co.uk

Yes, they are outdoor rated which probably you don't need, but do a really good job at clamping the cable. They also come with the "earthing nuts" that have a grub screw to lock them in place, and a tapped hole & screw for a ring terminal to add the flying earth lead. However, you can use the conventional ones with the "banjo" earth tag, or even just get the earthing nuts / piranha nuts separately.

However, double-check that is the right size for your cable!

Which isn't always the size it says on the packet.

Thanks again. Quality glands are one subject I am familiar with as I work in hazardous areas with Compex requirements. Appreciate the recommendation, i have mostly used Hawke but like the look of the earthing nuts you mentioned.
