Hi,

I am going to be running SWA cable out to the garage soon (Total run is
a little under 20em from the house CU to the garage CU)

I will also be installing a generator point on the garage, which will be
connecting to a proper transfer switch in the house.

It will be easier and cheaper if I just run a single SWA cable with 4
cores, two for the generator and two for the feed into the garage.

Is this permitted, or do I have to have two separate cables?

The SWA will be terminated in the house and garage in a metal box, then
the two circuits taken from there to there respective places.

Thanks!

Toby...
