Electrical questions, answered by experts

The key difference between a circuit breaker versus a surge protector is that circuit breakers shield your entire electrical system from overcurrents and faults, while surge protectors defend your electronic devices against voltage surges and spikes. A circuit breaker interrupts the flow of electricity in a circuit when it detects an overload or short circuit, protecting the wiring from damage and preventing fires. In contrast, a surge protector shields electronic devices from voltage spikes, such as those caused by lightning strikes or power surges, preventing damage to the device’s inner mechanics.

Durations range from an hour for simple jobs to full workdays for significant upgrades.

The process of hiring a reliable electrician begins by searching for local professionals and verifying that they hold a master electrician certification and the proper licensing for your area. After that, you should read through reviews from past customers to see the kind of service you can expect from the contractor, as well as look at the Better Business Bureau’s (BBB) website to check for a history of company complaints. You can also ask for customer references to make sure you’re choosing a reputable professional.

It wouldn’t be abnormal to view all wiring as simply wiring, but wiring has different gauges and can handle different loads. When you’re wiring for 240V, you need wire that is rated at least 240V, but honestly it’s better to spend a little more and just buy 300V wiring. This ensures a margin of safety in case the wiring gets overloaded.

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.
