"Hammer Electric showed up early for the appointment and was very nice and professional. Their pricing was fair for the 200-amp service and recess lighting they added for mew. They did an amazing job. Very neat while working and cleaned up their work area when they left. I will hire again for my rental properties and refer others. I highly recommend them for any electrical needs."

"JDV Electric recently replaced my electrical panel and delivered outstanding service from start to finish. The technicians were professional, courteous, and extremely knowledgeable. Before beginning the work, they took the time to remove the panel cover and thoroughly explain the existing damage, as well as how to prevent similar issues in the future. Unlike other companies that simply provided quotes without any explanation, JDV made sure I fully understood both the problem and their proposed solution. Their attention to detail and clear communication set them apart. The team worked efficiently and left the work area spotless, it was as if they had never been there. It?s rare to have a contractor complete a job without needing any cleanup afterward. I highly recommend JDV Electric for any electrical needs, and I will absolutely be using them again for future projects."

"Carlos is a PRO. Came out installed a new 200 amp electrical panel, conduit protected 200 amp line in, full bonding and grounding system, as well as ran a line and installed a generator interlock kit. He was thorough in showing me how to operate everything, the craftsmanship of his work was next level, everything up and running in a timely manner, and the cost was great. 10/10 would recommend for any and all electrical needs."

"We solicited three bids for the electrical work we wanted done in our home. We met representatives of three companies from our search of Angieâ s List and Home Advisor and received three different bids on the job. We then did out due diligence reading customer reviews and chose Generation 3 Electrical & HVAC. From proposal to completion, the people we interacted with were courteous, considerate, and professional. If youâ re looking for a company who employs licensed electricians who take pride in their work and know how to treat their customers, we highly recommend Generation 3 Electrical & HVAC. Our family wants to thank the office manager, Nicole, and the electricians, Corey, Ed, and Kevin for being courteous, answering all our questions, and for the great work you did at our home."

Electrical questions, answered by experts

A multimeter does not measure frequency, charge, inductance, and other electrical quantities. Instead, it measures voltage (AC and DC), current, and resistance.

When selecting a pool heater, it’s important to think not just about the cost of the unit itself but also about how much it costs to run. Expect to pay about $100 per month to run a heat pump pool heater. A natural gas heater will cost twice that amount, while an electric pool heater costs about $250 a month.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).

A piggyback circuit breaker, also known as a tandem or double-stuff breaker, combines two separate circuits into a single slot in a breaker panel. This design allows adding more circuits without a larger panel, making it a space-saving solution. Each breaker in the piggyback unit operates independently, protecting two circuits in one standard breaker slot. This is especially useful in older panels with limited space for additional breakers.
