I was told once that If the service loading was increased, such as by adding
a heat pump and hot tub, without notifying the power company, that the
homeowner
could be held financially responsible for damage caused by overloading the
power companies transformer or other equipment. When they get notified of
big
increases, they will upgrade the transformer if needed.

years ago that was true, now the poer companies dont care and in fact
let transformers overheat repeatedly till they burn out....

preventive maintence isnt part of their operation anyomore...

just recently they are talking of upgrading again along with a 20% $$
power increase
