Get matched with top electricians in Saint Johnsbury, VT

Q: Do I need a bigger breaker in my home if it keeps tripping?

• <div><p>A bigger breaker alone probably won&rsquo;t fix your problem of frequent tripping. But if you upgrade an electrical circuit to a higher amp rating, or upgrade your breaker box to handle more amps, it could solve your tripping problems. Consult a qualified electrician about the best course of action.</p></div>

Q: What are the wire sizes and numbers?

• <div><p>The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005&middot;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&rsquo;s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m&minus;1) or reciprocal centimeters (1/cm or cm&minus;1).</p></div>

Q: How do you install an outlet from existing wiring?

• <div><p>To install an outlet from existing wiring, you&rsquo;ll need to choose a location where you can already access existing wiring. The easiest way to do this is to install an outlet on the other side of the wall of an existing outlet. </p><p>Since the wiring is already in place, all you have to do is connect a new cable to the existing wiring and then connect the correct wires through the wall&mdash;to the new electrical outlet. Place your new outlet into the opening in the wall and then connect the correct wires to the appropriate terminal screws.</p></div>

Q: Should a refrigerator be plugged into a GFCI?

• <div><p>Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food. The only exception is when the refrigerator is in a garage, where all outlets must be GFCI.</p></div>

Q: What is the life expectancy of a home electrical panel?

• <div><p>The life expectancy of a home electrical panel is typically around <b>25 to 40 years</b>. However, this can vary based on usage, maintenance, and technological advancements. Regular inspections by a qualified electrician can help determine the condition and potential need for replacement as your panel ages. Factors like overloading, outdated components, or wear and tear might prompt earlier replacements for safety and efficiency reasons.</p></div>

Spencer is a very good communicator and responds to questions and requests in a timely manner. He was able to organize all the needed elements from land preparation to electrical to make the garage happen, leaving us with very little to worry about. We are completely happy with the end product of their labors and love how the new garage fits in with our existing home. We will absolutely look to O'Briens and Sons LLC for future projects around the home. Overall, the experience was professional, timely and a great investment! Thank you for making our garage come to life, Bill and Dierdra"
