 I bought an older house. How do I know if my electrical needs to be upgraded? It's really a tricky question depending on the age of the home. We have a big mandate for electrical safety in Ontario and one of it is aging infrastructure. Just getting a licensed electrical contractor in there to look at your service, the age of it. If you have fuses, typically the fuses are safe but the age of the panel and the overloading of a lot of those circuits warped the bus. So even if you have fuses and it looks good from the outside, typically behind the scenes it's actually pretty bad and could cause a fire. Anyone can hire the right people, a licensed electrical contractor to come in and do a test and troubleshoot. I'm never afraid of buying a house that's old and worrying about the electrical because as soon as you get in you bring in the licensed electrical contractor and say tell me what's wrong with the electrical. They'll quickly look through. That's how you all the problems, what's good, what's bad and what needs to be done to fix it.
