"We had an issue in our house, with some of our electricity being off and some remaining on. we were told, on the phone, that it could be one of a few things. Don and Pat came the next day, promptly at the time we were told. They checked out the system and told us that it was a line issue. Don told us that PSE&G should take the amount of his bill off our electrical bill. His bill was reasonable, even if we weren't able to have it deducted. We would hire DLP again."

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

Electrical questions, answered by experts

Volts and watts aren’t directly convertible units—they measure different aspects of electricity. Volts measure electrical potential, while watts quantify the power. The relationship between the two is defined by the equation: Power (watts)= Voltage (volts) x Current (amperes). In other words, the product of volts and amps results in watts, but there is no fixed conversion of volts into watts.

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).

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

Aluminum wiring can pose a significant fire risk because it tends to expand, contract, and overheat, leading to failing connections and splices. If your home has aluminum wiring, it doesn't always require a complete replacement, but you must take safety precautions. The first step is to hire a licensed electrician to conduct a thorough inspection. Based on their findings, you have several options:

  • Full Replacement: The safest but most expensive solution is to replace all aluminum wiring with copper.

  • Copper Pigtailing: A more budget-friendly option, suitable for certain homes, involves adding a short section of copper wire to the end of each aluminum wire at connection points.

  • Other Safety Upgrades: Your electrician may also recommend installing aluminum-compatible outlets and applying an anti-oxidant paste to connections to prevent corrosion.

Consulting a professional will help you determine the best course of action to ensure your home's wiring meets current safety standards.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.
