"WB Lightning Rods did an excellent job installing lightening rods on our home. The owner stayed onsite the entire time to supervise the work. 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."

"My daughter has a town home on Kent Island and had no protection from the home warrenty program issued less that three month eariler.  The dishwasher stopped working a month after settlement and all she was told was it was an electrical problem.  I turned to Bay Life Electric and Vern from my Angies list search he was the best person I could have found for the job.  He explained what was wrong and how he planned to fix the problem."

Electrical questions, answered by experts

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.

No, it’s extremely dangerous to cap off live electrical wires. Working with live wires puts you at serious risk of electric shock, which can cause injury or even be fatal. Whenever you need to cap off electrical wires or complete any electrical work in general, it’s essential to shut the power off at the breaker before you begin.

In general, 200 amps is enough for a house with a square footage of up to 1,800, or the average three-bedroom home. A 200-amp service allows your home to warm and cool itself while running multiple appliances at once. It's a good option for homes that have been extended, or after adding new appliances. 200-amp service is the current standard for homes, so in most cases, it will work for you.

Single-pole switches are simple circuits designed for lower voltages. As such, they don’t require the complex wiring of switches that need to supply power to larger devices and appliances. This is why single-pole switches commonly go in bathrooms, closets, and other small rooms that power a low-watt light fixture. One wire creates the circuit from the power supply, the other goes to the fixture, and the final wire provides safety mechanisms through grounding.

Yes, you must use the proper wire nut that fits your wire gauge. Using a wire nut that’s too big or too small can cause your connection to fail, short circuit, or disconnect entirely. Ensuring that you have the proper wire nut size will guarantee that your connection lasts as long as possible.
