How electricity works is a mystery to many people, and it’s common for us to have a lot of questions about electricity because of the potential dangers involved. Here we’re going to answer some of the most frequently asked electrical questions.

What’s the difference between a circuit breaker and a fuse?

Both have the same function – stopping the electricity from flowing when a fault occurs. Once a fuse trips it has to be replaced, but a circuit breaker can simply be reset. That’s why circuit breakers are a lot more common.

What does short circuit mean?

Excessive heat is created when a wire that is carrying electricity touches the grounded conductor wire. This sometimes creates sparks, and if you witness these then a short circuit has definitely happened. In this situation, you must consult a professional electrician for help.

I’ve seen an outlet say GFCI. What does that mean?

This is an electrical outlet that has been specifically designed to protect people from a potential shock if there is moisture present. Usually you will find these outlets in kitchens and bathrooms. Many will feature reset buttons because when moisture is present it automatically trips.

Why do I have frequent light bulb blowouts?

There could be a number of different reasons your bulbs are blowing. However, one reason may be because they’re overheating, which is a fire risk. If you’re having to replace a lightbulb frequently, you need to call in a trained electrician.

Is my electrical panel dangerous?

Most electrical panels aren’t dangerous as long as you know what you’re doing. If you don’t, it’s best not to touch them. Many homes have an outdated electrical panel which will need replacing to be able to power modern electronics and appliances.
