"It was a pleasure to deal with this company. They are extremely knowledgeable in designing an electrical charging station in what was a difficult i situation. My breaker panel and garage were on opposite sides of my home. A solution was given at a reasonable price. I could not be happier. All work was done professionally with great attention to detail. If you are in need of electrical services, donâ t look any further. They are without a doubt, the best."

"This was by far the best contractor experience I’ve had in many years. Rob is friendly, knowledgeable and professional. He was able to work within my budget and kept me informed during every stage of the process. My generator was ordered and installed in only one week, which was also very impressive. I would highly recommend Buckley & Son Electrical Contractors."

"I'd like to give a AAA+ rating to Ron and Jeremy owners of Cawiamca LLC. These guys are top notch! Ron provided competitive pricing for my new furnace system and installation. Jeremy did the install in less than a full day. I've had the system for little over a year. They came back this fall for an annual cleaning and I signed up with them for a service contract. Fast forward to December 24th Christmas eve. We lost power in Essex and my generator tripped the furnace off due to a surge. I called Ron who was out of state at the time. He phoned me back within 15 minutes. He then sent Jeremy over to survey and fix the problem. Jeremy explained he was on his way out for family festivities when Ron called. He got it up and running quickly. It was a very nice Christmas present for me. I can't stress enough how rare great customer service is these days. Cawiamca LLC. provides awesome customer service! —John M, Essex CT"

Electrical questions, answered by experts

You can run a small or basic standard-size refrigerator on a 15-amp circuit. But you should plug a modern, standard-size refrigerator into a 20-amp dedicated circuit. The refrigerator needs to be on a dedicated circuit, meaning it is the only appliance and outlet on that circuit breaker. This method prevents tripping the breaker and reduces the chance of an electrical fire. 

You should always turn off a breaker whenever electrical work is being done. This step can prevent electrical shock and injury. Also, if a breaker is repeatedly tripping, it can mean there is an electrical overload, and it should be shut off. You should contact an electrician to figure out the cause. Make sure to review how to turn off your circuit breaker safely if you do it yourself, and follow safety precautions to avoid severe injuries.

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.

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.

It’s possible to distinguish a positive black wire from a negative black wire if you know what type of circuit the wires are in. If it’s an alternating current (AC), then black wires are positive. If it’s a direct current (DC), then black wires are negative. 

Sometimes, a circuit has two black wires. In that case, the positive black wire will be solid black while the negative black wire will have a white stripe on it. If you’re still unsure, you can use a multimeter to check.
