"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

With AC wiring, which is the kind most likely you’ll find at home, the black wire is “hot,” and the white is “neutral.” The bare or green wire is considered the safety ground wire. If you encounter DC wiring, it’s relatively easy to tell positive or negative wires apart. red wires are used to indicate positive voltage and black wires indicate negative voltage.

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.

Typically, refrigerators should not be plugged into GFCI outlets. This is another appliance with a motor that can be prone to a little current leakage. Using a standard outlet saves nuisance tripping and the potential of waking up to a refrigerator full of warm food. The only exception is when the refrigerator is in a garage, where all outlets must be GFCI.

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Yes, dehumidifiers use a lot of electricity. However, proper humidity also means your home’s temperature remains more stable, thus lowering heating and air conditioning bills. The good news is you shouldn’t need to use a dehumidifier more than a few months per year, so the energy costs won’t be as noticeable as other larger appliances.
