"If you're looking for an honest and knowledgeable electrician, R.A.P. Electric Company is the real deal. When my master bathroom outlets suddenly lost power, I spent hours checking breakers, outlets, and GFCIs without finding the problem. After contacting R.A.P. through Angi, I expected a service call and a bill. Instead, the electrician took the time to ask a few questions and patiently guided me through troubleshooting over the phone. He helped me locate a forgotten GFCI outlet in my basement that had tripped and was causing the problem. Once I reset it, everything worked perfectly. Many electricians could have charged me for a house call to perform a 30-second fix. Instead, R.A.P. chose honesty and customer service over making a quick dollar. That level of integrity is rare these days. I will definitely use R.A.P. Electric Company for any future electrical work and highly recommend them."

"I had an electrical issue in my kitchen and the power to main floor went out. I ended up having a back switch that needed to be replaced. I was quickly contacted to understand the issue, and DLP Electric was willing to come out today, however I had already just hired a technician from another company to handle (right before I spoke to DLP). Having said that, DLP Electric was professional and very helpful, and I would hire them if I ever needed electric work performed in my house. Great customer service and very responsive."

Electrical questions, answered by experts

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.

The copper wire used in knob and tube wiring systems can last up to 100 years. However, it’s considered a dangerous and outdated wiring method because the cloth, fabric, or rubber insulation sheathing can become brittle and fall apart. Knob and tube wiring systems should be inspected if you’re considering buying a home with this type of wiring, or if you have problems with frequently tripping breakers, a sign that you may need to replace them.

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.

Yes, but our analogy with the water hose doesn’t really work here. You see, electrical flow isn’t constant: It ebbs and flows like waves, coming in pulses of power. Hertz measures the rate of change in the flow of electricity, or how often it ebbs and flows. For example, 60Hz means that the electrons pulse through wiring 60 times per second. When they are pulsing, they’re in a brief retreat. Almost all United States equipment is rated for 60Hz.

If you connect the wrong electrical wires together, it can lead to a very dangerous electrical shock. All wires should be matched with wires of the same color. It’s very important to consult an electrician if you’re unsure about how to wire your fixture.
