"Had an electrician out to give me an estimate on replacing my electrical panel. Decided against replacing it because that wouldn't have solved my issue. My house was built in the 60's so it needs all new wiring. I just had him show me which outlets were on each of the channels so that I could spread out my devices that needed a lot of power, specifically my space heaters."

"Called M.Y. Electrical for a 200 amp panel upgrade estimate. Luis came out the next day and had a very clear explanation of what need to be done and the timeframe involved, along with a very fair estimate. The crew: Luis, Jesus, Michael and Miguel came out a few days later to do the job. I am impressed, everyone on the crew did excellent work. Due to their knowledge and work ethics they made it stress free for me. Luis took care of obtaining the proper permits. He also informed me through texts of their arrival times, and inspection times, and being here during inspection. After electrical work was completed Javier repaired the stucco, also well done. Very happy I chose M.Y. Electrical and Louis and his crew to do the work!"

Electrical questions, answered by experts

A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

Most standard residential water heaters, which are typically around 40 gallons and use 240 volts and between 3,500 and 5,500 watts, require a 30-amp, two-pole circuit breaker. For smaller, point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts, a 30-amp breaker is also often adequate. However, some models may have different needs; units that use more watts than average may require a 40-amp breaker, while smaller units might only need a 20-amp breaker. Newer, tankless, or more energy-efficient models can also require a higher amperage. Having the correct breaker size is crucial for safe and efficient operation, so it's best to consult a licensed electrician to determine the specific needs of your water heater.

For more complex electrical projects, it’s often most efficient and cost-effective to hire an electrician rather than trying to figure it out yourself (and risking electrical problems). Electricians know exactly what a project requires, and can often find supplies or parts for cheaper than the average homeowner. That can save money compared to going it alone.

No, wiring does not need to be redone to get a dimmer switch, as they work with single-pole and three-way switches. Just ensure you choose a dimmer that is compatible with your wiring, fixture, and lightbulbs. Most homes built after 1985 have neutral wiring and work with almost all dimmers. If your home was built before 1985 and you don’t have an updated electrical system, you may have to use a non-neutral wiring dimmer.

By nature, two-prong outlets aren't grounded—but the box they run to might be, which makes them safer. The safest way to test if an outlet is grounded is to purchase a circuit tester, which cost about $20 at home improvement stores. 

If you discover your outlet (or outlets) aren't grounded, know that this greatly increases your risk of personal injury and electrical fires. You may want to consider installing new three-prong ground fault circuit interrupter (GFCI) outlets. On average, the cost to install GFCI outlets is about $210 per outlet.
