  • Which is better -- Fuses or Circuit Breakers?

    In some ways, the old fashioned fuse is actually better than the circuit breakers. To make sure I got my facts right on this one I visited George Brown College in Toronto to talk to one of the instructors in the electrician's apprentice programs. Fuses are 100 % reliable. When they get hot, the...
  • Aluminum to Copper electrical connectors

    THE WIRE WORKS, THE CONNECTIONS ARE THE PROBLEM Aluminum wire does a good job of conducting electricity (although you do have to use one size larger wire than copper for the same electrical load) and can do the same job for less money. So for a short while it was used in houses for regular wirin...
  • Sparks flying out of the circuit breaker

    I live in a basement suite and our lights and electrical outlets on one side of the suite blink and stutter a lot.

Many of those efforts created great problems for the utility because homeowners were often feeding electric...
  • Can I save money by turning my hot water tank off at night?

    Thomas from London, Ontario writes: "We have an electric water heater. To conserve electricity, I turn the heater OFF at its circuit breaker at night before retiring and then ON when I return from work. This usually gives plenty of hot water while at home. Does this cause any premature "wear ...
  • New circuit protection: Arc Fault Interrupters

    Overload protection Fuses and circuit breakers will stop the electricity in a wire when the load is excessive or there is a short circuit.

  • How do you know which fuse protects which outlet?

And then there's yelling... 'Is that the one?'....
  • Does an electrical panel have to be behind closed doors?

    No. That was simple wasn't it?Actually the contrary is a bit the case -- electrical panels should never be blocked or made inaccessible.Olive from Calgary even showed us the beautiful use of Oak cabinets to hide the panel while leaving the panel still accessible. She even keeps all her important...
