"Two workmen showed up at the designated time and installed 'in wall' electrical for undercabinet lighting in the wall along with trouble shooting additional 3-way light switches, dimmers, and USB outlets. Work was fast, efficient, and professionally done within the allotted time. Would definitely recommend and will use Nasr Electrical again in the future."

"not just professional efficient! Unbelievably fair priced literally less than half of what a major competitor on this site quoted using my own parts and my own wire! Just because there are any energy list doesn’t mean some people won’t try and rip you off and fools will pay it. Mr. NAGY is a professional and very ethical. I’d recommend hiring him again and again!"

"I hired Vital Electric to assess and fix multiple electrical issues in my new home. Lidwing quickly resolved a reversed polarity outlet, corrected a double-fed garage circuit, and addressed a panel safety concern—all within a two-hour window. Professional, efficient, and knowledgeable. Highly recommend."

"How did it go? Not well. I finally just bought the required ladder at 200 USD and did not pursue Kolb Electric further. I should have just bought the ladder in the first place. Live and learn."

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.

Inverter generators are designed to turn on the engine when your appliances demand more energy. This is in contrast to running at full capacity as soon as they’re turned on, like a standard portable generator does. So long as the wattage rating is high enough, an inverter can power a refrigerator just as well as a traditional generator.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

For a 200-amp underground service, you need a minimum of #2/0 American Wire Gauge (AWG) copper or #4/0 AWG aluminum or copper-clad wire. Don’t forget that, at minimum, you’ll need to use a 1 1/2-inch schedule 40 or 80 PVC conduit to successfully run a 200-amp underground service.

Aluminum wiring can pose a fire risk as it can overheat, expand, and contract, leading to failing splices and loose connections. If your home has aluminum wiring, it requires careful maintenance and potential safety upgrades. The first step is to hire a licensed electrician to conduct a thorough inspection.

A complete replacement with copper wire is the safest option but can be very expensive and is not always necessary. Other safety measures and upgrades include:

  • Copper Pigtailing: A more budget-friendly option where a short section of copper wire is added to each end of the aluminum wire. This is only appropriate for certain homes.

  • Aluminum-Compatible Outlets: Installing outlets specifically designed for use with aluminum wiring.

  • Anti-Oxidant Paste: Applying this paste to connections to prevent oxidation.

Consulting with a qualified electrician is essential to assess the condition of your wiring and determine the most appropriate updates to meet current safety standards.
