Garage electrics

[always-diying]

I know this topic has been done to death but after searching I can't find an answer to my problem.

I am intending to run a circuit to my garage about 20ft from cu. Running from spare 32a MCB in CU (RCD protected).

Power for fridge, tumble dryer, some light power tools.

Intending CU in garage with 32a MCB using 4mm2 cable in radial circuit for 2 double sockets.

Do I have to use SWA from house CU or can I use T&E in conduit, if so what size of cable should I use?

You can search TLC-direct to get your cable size and you will get a lot of satisfaction working it out for yourself

No you don't have to use SWA but if your garage is not connected to your house then SWA is the easiest DIY install. Your cable size will be 6mm+ so you would need 25mm steel conduit. You could use black plastic conduit but IMO that does not offer enough mechanical protection for an external sub-main.

So that you know where you stand with regulations have a read up on building warrants

I'd go for SWA its much stronger than any other cable out there
