That's a good point.... My house is old - built in 1954 - and has been
"re-muddled" several times, often by owners. I've corrected some of the
most egregious wiring errors but who knows what lurks in the walls.
That might even fit with the time; if people come home around 5 or 6PM
power usage goes up and voltage might drop....
I've always wanted a kill-a-watt; now maybe the time to get it. :-)
