"Scott is excellent to work with in all aspects of electrical. I am a general contractor and Moses Electric has done all my electrical for the past 12yrs. I look to no one else. From the non working outlet or switch, to service upgrades, underground work, data, fire alarm panels, low voltage, new construction, remodeling, troubleshooting, all the way to 3 phase industrial and commercial work. Scott has been along side me for all aspects of the electrical work and never skipped a beat. I have full confidence to refer Moses Electric to my own clients, friends and family. Knowing when I pass his name along it will not come back to me with a negative effect. Always happy clients every time, in addition to being clean in all aspects of presentation and workmanship. I am not biased because I am in the trades. We rely on referrals and relationships to provide our living so there is no benefit to saying what isn't true. I highly recommend Scott and Moses Electric for any of your electrical needs. He makes the process easy and seamless."

"Arete’s team was incredibly professional and efficient. They completed my HVAC job in a timely manner and beat competitor’s pricing. Their team was very respectful of my home and even wiped the floor after each day’s work. Every member of the team was kind and respectful. Will certainly work with them again in the future for any of my HVAC/electrical needs."

"I came home on a 90 degree day with half my bedroom having no electrical including AC. He called me right back. He went through and fixed the problem and explained everything along the way. The price was very reasonable. I would absolutely recommend him to anyone needing electrical work. Didn't push anything extra either. Great guy too!"

Electrical questions, answered by experts

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

If you’re replacing wires from an electrical meter box to the breaker box, you may also consider installing a new meter or replacing or repairing the breaker box . You can tell if the circuit breaker is bad if you’re dealing with tripping or worrisome burning smells. Both projects should also be handled safely by a licensed electrician.

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

If a 240V appliance is connected to a 120V outlet, the lower voltage will cause that appliance to receive insufficient power. This may result in reduced performance, malfunctions, or even damage to the appliance's components. Depending on the size of your electrical circuit, you’ll likely need to reset a tripped circuit breaker at the very least.
