Was in a house the other day where as far as I could tell there were

Um, that's just one radial circuit.
Shouldn't be a problem unless the loading is silly,
like if it's doing a large kitchen and utility room.

But since this is the normally thoroughly sensible Martin A speaking,

Aww... blush I don't think anyone's been that nice to me for ages...

....except the wife. I have to say that in case she reads this sometime.

probably meant precisely that the four main branches of the single
radial were indeed supplying loads/floor-areas considerably in excess
of the reasonable burden on a single 20A circuit (not to mention the
controllability/incovenience factors), and expected us as intelligent
readers to infer this from context...


Yes, sorry, I wasn't really making myself clear (or really thinking
clearly). This is exactly what I meant. The sockets in the whole house
(3 bed end-of-terrace) were run (IIRC, and I'm not looking the details
up now) from this single 20A MCB. I'd guess a floor area of over 80sqm,
but more to the point:

A washing machine
A tumble dryer
An electric kettle
A microwave oven

Granted, not often likely to be on at the same time, but still an easy
8kW.

Oh, and it was a 20A *fuse* by the way, bit of semi-enclosed, none of
this modern cartridge stuff... err, and some of the 2.5mm2 was 1mm2 CPC
rather than 1.5mm2. Ummm... and the earth rod (which must have existed
somewhere because the earth loop reading wasn't sky-high even though
gas and water weren't bonded) was nowhere to be seen.

Hwyl!
