"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall.

Electrical questions, answered by experts

There are various reasons why an electrical outlet can stop working. You might have to do some detective work to understand whether it’s a problem with the attached appliance, the outlet itself, or a faulty breaker. Sometimes, old age or loose wiring are to blame; other times, it can be as simple as an overloaded circuit tripping the system and cutting power. If you’re troubleshooting doesn’t solve the mystery or repairs, or replacements are required, it’s time to call in the pros.

A larger heater requires a larger breaker—unless there’s one already installed. The longer answer to this question is more nuanced. Do you place demands on the heater at the same time as running other heavy-duty appliances like ovens and washing machines? Do you live in an older home that may not have considered the higher electrical demands we have now? Breakers need to be sized at 125% of the load. To find that load, you should call a local electrical pro.

You should not attempt to disable a smoke alarm unless you’ve already activated a replacement unit. To stop a hardwired smoke alarm from beeping, reset the device or silence the alarm. If you’re removing a hardwired alarm, shut off the power, turn the unit counterclockwise to remove it from the ceiling, and disconnect the wiring.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

The average lifespan of a home electrical system is anywhere from 30 to 70 years or more, depending on the type of system you have. Modern electrical wiring, like aluminum or copper, can last 50 to 70 years while older types may need to be replaced sooner. Additionally, circuit breakers tend to last anywhere from 30 to 40 years, while electrical outlets need to be replaced every 10 to 25 years.
