"Klaus moved our wired electric panel and re-wired the entire kitchen. He added amazing lighting including recessed lighting, under counter lighting and toe kick lighting. He installed relocated electrical receptacles for the dishwasher, garbage disposal and water pump. Did beautiful finish work. Very good at communicating and saying yes when I asked for more. Pricing very reasonable. Very dependable and amicable. Highly recommended."

"On August 2025 I had two Hunter ceiling fans installed by Mike and was very pleased with the results. The installations were done efficiently and professionally, with both fans mounted in the second-floor loft and bedroom with 8’ ceilings. Communication was clear throughout the process, and he made sure everything was working perfectly, including the wall controls for each fan. I highly recommend their services for anyone needing reliable and quality electrical work."

"I hired W B Lighting Rods/William Burden to install lightning rods on my home. I spoke to William on a Monday and by Thursday before 1 PM the lightning rods were installed on my home. William explained everything he was going to do before he did it. The lightning rods were affordable and most of all it gives me peace of mind knowing that my home is protected against lightning strikes and fire damage. I couldnâ t be happier with this company!!"

"Very professional and efficient. Arrived timely, very knowledgeable, and efficiently repaired appliance. Our General Electric large refrigerator was not properly cooling. Found door leakage, ordered the part, and returned to replace the seal. No markup on the part, no added time to repair - entire transaction was very fair. Could not ask for a better experience."

Electrical questions, answered by experts

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

A duplex outlet simply means that the receptacle has two plug-in outlets for two plugs. It’s a common design choice for homes. The two outlets should be wired identically during installation so the hot side is the same for both.

If the fan doesn’t have a switch, connect the white wire from the ceiling to the white wire from the fan; connect the green wire to the ground wire; connect both black wires; and connect both blue wires. If yours has a switch, the white and green wires are connected the same way. However, connect the ceiling’s red wire to the light’s black wire and the ceiling’s black wire to the fan’s black wire. 

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
