"I recently had Best Dressed Electric replace my doorbell chime and fix some lighting issues in my home, and I’m extremely satisfied with the service. They were prompt, courteous, and efficiently resolved both issues. The doorbell chime works perfectly now, and the lighting is brighter than ever. I highly recommend them for their excellent workmanship and professionalism. Thank you for your excellent work!"

"So happy with my experience with DK Electrical. Contacted me quickly to arrange for an estimate and work was scheduled before they left my home after I accepted the price quote. Arrived for the job at the time they stated. They were professional and let me know status as they were completing the work. Coordinated the township inspection. I will definitely contact them again for electrical work."

Electrical questions, answered by experts

No, not all thermostats require a C-wire. Older manual and programmable thermostats typically do not need one. While many smart thermostats do require a C-wire to function correctly, some models can operate without one, often at the expense of certain features. A C-wire provides a constant source of power, which enables the thermostat to stay connected to Wi-Fi and keep its display screen lit on-demand. If you are upgrading from an older thermostat to a smart model that requires a C-wire, you may need to install one first for it to work as intended.

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.

Your heating and cooling systems cost you the most on your electric bill and make up 50% of your bill on average. Your washing machine, dryer, oven, and stove contribute significantly to your electric bill as well. Lights, fans, and smaller electronics add up, but aren’t the biggest energy consumers. You can reduce your power usage by setting optimal temperatures on your thermostat and investing in energy-efficient appliances.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

If the electrical wires you’re working with are too short, one of the easiest ways to elongate it is to extend them with a push-in connector. These user-friendly tools help you splice two wires together with little fuss or the need for extra tools, like a crimping tool, which is an older way of extending wires. As long as you can stripe the ends of a wire, using a push-in connector shouldn’t be an issue.
