"Marsh River traveled over an hour to come out to my house to redo my electrical from the panel to the pole, put the wires underground (because they were not before) put a new electrical box and meter on the pole. Did a great job and knew exactly what they were doing! Just a side note: I thought the reason the outlets on the back wall of my room didn’t work was because of mice eating our wires. Whoever did the electric before must not have done it correctly because the outlets are now working!"

"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"I got an estimate from another company, but once they place the generator I then needed to contact someone else to connect it to my gas line. Generator Supercenter completed everything. Plus, they contacted the gas company to schedule replacement of my old meter."

Electrical FAQs, answered by experts

A two-way switch is also called a single-pole or single-throw switch. These switches only have an on-and-off function and only control a single light or series of lights wired together. A three-way switch has no “on” or "off” position and works with a second switch in the circuit to control a single light or light series from two locations.

You can install a three-prong outlet without connecting any ground and plug in three-prong electronics into that outlet. The devices will function normally, but you won’t get any of the protection that grounding provides, so there’s an increased risk of serious problems if something goes wrong.

There are several reasons why an electrical outlet would suddenly stop working, including:

  • Broken parts in the outlet

  • Outlet burnout

  • Circuit breaker tripped

  • Damaged circuit breaker

  • GFCI outlet tripped

  • Damaged or loose wires

  • Failed connectors

  • Appliance failure

If the outlet is a GFCI model, this is normal since these outlets have their own breakers that shut off when they encounter a problem—just hitting the reset button should solve the issue. Otherwise, the outlet could have bad wiring, or your circuit breaker could be having issues. If the issue started out of nowhere and is not on a GFCI outelt, it’s best to contact an electrician to diagnose the issue.

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.
