"Simon and Keaton were great; They were timely and efficient and explained the pros and cons every step of the way. The end result of our outside lighting project was wonderful. Our neighbors immediately called us to compliment the job and asked who did it. We were delighted to refer them to Prodigy and will use them again for any future electrical needs."

He took extra care to plan the rod and cable placement to ensure the proper protection and retain the aesthetics of our home. His crew were knowledgeable, polite, neat and efficient. We could not be more pleased with the results."

Electrical questions, answered by experts

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.

In the case of electrical overflow, an ungrounded outlet should trip the circuit breaker, staving off dangerous scenarios. However, this is not always the case, especially if the wires and circuit breaker are worn down or damaged in some way. Ungrounded wires melt over time as they are introduced to more and more electricity. In other words, a circuit breaker offers protection in most instances but not always, and that’s where the danger lies with ungrounded outlets.

Rewiring an electric system in a house typically ranges between $2,000 and $9,000, but a simple project can cost as low as $1,500. More complex upgrades run $10,000 or higher. The price depends on the size of your home, how accessible the wiring is, the cost of materials, and local electrician fees.

You can determine whether you have a double-pole switch by examining its wiring. Unlike single-pole switches, which have two brass-colored terminals, double-pole switches feature four. These switches are typically only found near high-powered appliances such as electric furnaces or water heaters. If you’re unsure what type of switch you have, contact a local electrician to confirm.

Circuit breakers can wear out, but it takes a long time. Circuit breakers typically last several decades if they don’t face problems like floods or frequent lightning storms. Worn-out circuit breakers may trip more frequently as time passes. However, they can also stop tripping altogether, which leads to electrical dangers. If your breakers have passed the 30-year mark, it’s time to consider an inspection.
