A relative lives in a 300-year-old house. Yesterday he called to warn
that when I visit tomorrow (Friday) it's likely that roughly half the
house will still be without power. The other, smaller, half is
unaffected.

The electrician he called has so far not been able to diagnose the
cause of the problem. The half that is out is on a separate "fuse"
box. The other half of the house is unaffected. I write "fuse" in
quotes, but I understand that it does at least have the switches, not
old-fashioned fuse-wire fuses, although the equipment seems to be very
old.

That leaves a lot of room for speculation untrammelled by facts

As already noted, pictures might help - ideally of both fuse boxes and
of where the cable comes into the house. It might also help to know if
the supply to the house is from overhead cables.
