i have been asked to run power to a timberframe outbuilding (6mtr x 10mtr).
there is a garage cu which is a submain of the main cu, which would be easier and more practical to run the power from.
i havent actually been to the site yet, but assuming suitable CSA feed to the garage cu, can i then feed off from the garage cu to another cu in the outbuilding?

That rather depends on the design loads and the cable sizes.

Surely you know this

You might find it difficult to co-ordinate the ratings of MCBs if any of the new final circuits is anything more than 6A.

I don't think that it's too critical although your correct if it was any other type of installation ie commercial there would be more of a risk/inconvenience.

Hi - perhaps service split before the garage CU to avoid adding to co-ordination issues etc. I’m seeing SWA entering garage and having some half baked connection to that CU (oh so many of these). Fix that with an adjacent box and add a new SWA ongoing to the next shed, perhaps.
