"I hired HES last year to do an upgrade on our electrical panel. There wasnt a day that went by without our electrical panel popping or power going out. Our house was built in 1962 so it was 58 years old and had nothing done to it. During this process the previous box disintegrated and additional repairs needed to be made! It was a worse case scenario.. it didnt phase HES, they were quick and prompt to take care of the issue and completed the project on time ! Even though there was additional money due to the worse case incident, It was still within my budget guidelines. I have never felt more taken care and received such a great customer service in Moses Lake in a VERY LONG TIME! HES not only took care of the items listed but was polite and very punctual. I would recommend HES ANYTIME AND WITHOUT RESERVATION !! Thank you HES for such good quality work."

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires.

The average radon mitigation system uses about 876 kWh of electricity per year, although the exact amount of electricity used will vary depending on the size of the radon fan. Once the system is installed, the annual increase to your energy bill could range from $30 to $300 per year, again depending on the size of the fan.

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, electricians must be licensed, certified, and in most cases, insured. Licensing requirements vary by state and local municipality, but most U.S. municipalities require electricians to hold an electrical contractor’s license. It's always a good practice to confirm requirements with your local municipality. Even if licensing is not required in your area, hiring a licensed and experienced electrician often leads to a better end result.

A license is a legal requirement to operate a business and is necessary for pulling project permits. Certifications, on the other hand, are typically voluntary and demonstrate a certain level of expertise. In some cases, a certified electrician may send an apprentice or journeyman to perform the work, but they must operate under a primary electrician who holds the proper license.
