"Hamilton Electric was so quick to respond, quoted a price and was able to come out to do the work as quickly as I needed. We had a bit of a delay from PG&E and Brian was very patient and helpful even with the changes in timeline. Technician came out today and was quick and efficient. We thought we would be without power all day, but instead it was only a few hours. We will definitely call Hamilton Electric for any other electrical needs at our home."

"Single Line Electric came to my house to view my need. 2 other companies I called wanted me to send a video of my home showing them my yard from the electrical box to my pool. They obviously didn't want the job. Nery came out and did a thorough assessment of my needs. His quote was reasonable and the project began soon after. I am very pleased with with Single Line Electric"

"Robert did an excellent job installing LED ceiling lights in our family room. I couldn't be happier with the finished work. The installation was very neat and professional. I would not hesitate to call Robert again for any future work. I will be referring Robert to anyone that may need some electrical work."

Electrical questions, answered by experts

Smart meters send the readings over a wireless wide area network (WAN) to the power company. This network allows sending small amounts of data slowly over long distances, which is perfect for smart meter readings that occur monthly. If you would prefer a smart meter, contact your power company and consider springing for the cost of replacing your electric meter.

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.

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

If your breaker box won’t reset, stay on, trips when overloaded, or gets seriously damaged, you will need to replace the breakers or possibly the entire panel. A damaged breaker can lead to a fire, so it’s best to err on the safe side and look into replacement. Hire a professional electrician to replace a breaker box to ensure your personal and property safety.

There are several things to try to repair a broken outlet. Whether it's fixable or not may depend on the problem and the type of outlet itself. Start by testing the circuit with an electrical tester and ensuring the breaker switch to the circuit functions as it should. Loose wires are sometimes the culprit and are repairable by fixing the connections.
