Modern Ontario homes run EV chargers, heat pumps, induction ranges, and finished basement suites that easily exceed the capacity of older 60-amp fuse boxes or 100-amp breaker panels.

1. Breakers That Trip Repeatedly

If running the microwave and kettle or hair dryer trips a breaker, the circuit is overloaded or the breaker thermal mechanism is weakening.

2. Lights That Dim When Appliances Start

Brief dimming when your central air conditioner, heat pump, or sump pump starts can indicate loose neutral connections or undersized service capacity.

3. Warm Panel Cover or Crackling Sounds

An electrical panel cover should always feel cool to the touch. Warmth, discoloured breaker switches, or buzzing sounds require immediate inspection by a licensed electrician.

4. Planning a 200-Amp Service Upgrade

Always hire an Electrical Safety Authority (ESA) licensed electrical contractor who pulls a formal ESA permit and coordinates the hydro disconnect and inspection.
