Yes, the house is 2500 sq ft and is on I think 100 or 150amp breaker
box. I was told in the past that for one the breaker box is too small
and second that the wires are not correctly segmented - there's been
alot of add-ons throughout the years of the previous owner and myself
as well. We also have an issue where one of the upstairs bathrooms
blows a fuse everytime the hairdryer is used. Odd thing is I go
downstairs and the fuse doesnt look completely tripped, but a switch
off/on does the trick. We have since stayed away from using the
hairdryer in that room - i know not the solution though.

Breakers go bad too. The cheapest thing to do is buy a breaker for $6 or so at Home Depot. I had one
that was acting weird lately and I changed it. All is fine now.
