"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."

"Upgrade by James G. (JZG Electric) James G. from JZG Electric did an outstanding job on our main panel upgrade. From the very beginning, he was prompt, professional, and incredibly thorough. He took the time to walk through the existing setup, explain the required changes in plain language, and outline exactly what to expect during the upgrade. On installation day, James worked efficiently and with clear attention to detail. His workmanship is clean, organized, and clearly reflects a deep understanding of electrical systems/code and safety standards. He coordinated the utility shut-off smoothly, kept the workspace neat, and ensured everything was brought up to code without any surprises. After the upgrade, he double-checked all circuits, labeled everything clearly, and made sure we understood the new panel layout. The difference in reliability and safety is immediately noticeable. Overall, James delivered exceptional service from start to finish. Highly recommend JZG Electric!"

Electrical questions, answered by experts

Yes, it’s possible to use a three-way switch as a two-way switch. You can use a three-way switch as a two-way switch by bypassing one of the traveler wires and using only one of the available traveler switch terminals.

To fix a tripped light switch, locate your home's electrical panel and identify the tripped circuit breaker. It will be in the "off" or neutral position. Flip the breaker entirely to the "off" position, then switch it back to the "on" position. If the breaker trips again immediately, there may be a short circuit or overload in the system, requiring further investigation. If the switch still doesn't work after resetting the breaker, check for loose wires or faulty components in the switch itself. It is always best to consult a licensed electrician for persistent issues and when in doubt.

In many cases, yes, upgrading your electrical panel can lower your electric bill. Upgrading an outdated electrical panel can make your home more energy-efficient, so you consume less electricity and spend less on utility bills. However, to see these savings, you’ll need to invest quite a bit. On average, installing a new electrical panel costs $1,200 to $2,000, with most people paying around $1,600.

Yes, a light switch still has power even when switched off. Switches only interrupt or continue the flow of electricity into a fixture or outlet; they do not shut off the power flowing into the wire. The only way to shut off power in a light switch is to turn off the power at the circuit breaker.

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.
