"Max followed up quickly after our initial inquiry, and scheduling an appointment was a piece of cake. He arrived at our home promptly at our agreed upon time and quickly fixed what we needed done for a very reasonable price. We would definitely use Unstoppable again for any future electrical work."

"This is a truly great company. They provide great customer service and spend time explaining the details and answering questions. My husband obsessed about every single detail and could not deny that it was a no brainer. Our first electric bill since installing the panels was a CREDIT! I was not expecting that. If you have ever considered solar, seriously, just do it. Long term, you can not go wrong."

"They did great, swapped out an outlet so that it would work with our new AC, handled everything over text and asked detailed questions, and was super patient with the fact that I had no idea what I was doing. They were able to come out the next day and the outlet works and looks great, they were in and out pretty quickly and were super professional the whole time. Would highly recommend these guys, and would definitely go with them in the future if we need more work done. Also was super kind to ask if vacuuming was ok, or if it would freak our cats out, and our super grumpy little cat even felt comfortable coming out while he was around, too. Great experience overall. Thanks!"

"In 2019 I bought an older home and hired ICRA Electric to rewire the entire home including upgrading the electric panel. Aaron Mattingly (owner) was referred to me by someone I trusted. I typically only use contractors by referral. Not only was his bid lower than the other bids I had received, he was very flexible with my schedule and accommodating with changes I made throughout the job without gouging me. Aaron also provided practical electrical suggestions for future needs that I wasn’t even thinking about and ensured everything I wanted was completed according to code. I have never done an online review in the past, but it is rare these days to find a contractor that is more about making sure you will be happy with the final product for years to come than getting as much money out of you as they can. There are many reputable contractors out there. The challenge is navigating through the others who don’t want to be found out. ICRA Electric is one of the good ones."

Electrical questions, answered by experts

The safest way to pull an electrical cord from the wall outlet is by gently but firmly grabbing the plug and pulling it out. Pulling on the cord instead of the plug can cause damage to the cord, leading to an increased risk of electrical problems like fire or electric shock. If you notice damaged wiring on an appliance or device, it’s best to stop using it immediately.

Yes, one wire is always hot on the 3-way switch, meaning it carries the electricity from the power source to the switch. If you have a 3-wire cable in your home, you have two hot wires, or line wires, coming from the power source. Typically, you’d connect the hot black wire from the power source to the traveler wire and the hot red wire from the power source to the first 3-way switch. For the second 3-way switch, you’d then connect the hot black traveler wire to the switch.

Incorrectly wiring a single-pole switch results in the connected light or device not turning on or tripping the circuit breaker. Although it doesn't matter which terminal the hot wire and the load wire connect to, mixing up a circuit wire with a ground or having loose connections can prevent the switch from working. 

Yes, a whole-house surge protector needs a designated breaker in your electrical panel. You will need to choose a double pole breaker that has two wire terminals so that your surge protector can connect to the breaker. This breaker needs two breaker slots inside of your panel. If you do not have room, then you will either need to adjust some of the existing breakers in the panel box or hire an electrician to install a subpanel.

A C-wire connects your thermostat to your household heating and cooling system to provide continuous 24V power. The furnace's transformer converts household electrical current into this low-voltage power to operate the HVAC system's circuitry. In most configurations, the C-wire connects to the terminals labeled "C" on both the furnace's low-voltage terminal block and the thermostat. In some cases, if a dedicated C terminal is unavailable, the C-wire can be connected to the "G" (fan) terminal at the furnace.
