Re: modern electrical goods being higher power and hence demand on consumer units being higher too, I respectively disagree. Energy efficiencies in lighting and heating and washing etc mean that all of those things will draw less current than their equivalents back in the day, I reckon?
It's not those items (lighting, washing, heating), it's the items that didn't really exist (or were much smaller) back in say the 60s.
No 1000W+ microwave ovens in the '60s. No 500W computers back in the '60s. Kettles weren't 2400W+ back then either.
Conventional ovens often ran off a 13A plug (although my modern oven is small enough that it does). Newer ranges can be rated at 40A.
Etc.
