"I highly recommend Plugged In Electric to anyone needing electric work/repair. You can hire them with confidence in a job well done, being on time, and charging a reasonable cost. Plugged In Electric not only met my immediate needs but also made recommendations for future improvements. In addition, I had a sagging electrical line feeding my house. The technician contacted TEP directly to fix this, TEP came out the same day and fixed it. Without the technician's knowledge of who to contact at TEP, I was at loss as to how to get this safety issue that I'd had for 15 years fixed. I didn't even know this is a service TEP provided for free! Cudos to Plugged In Electric."

"Fabulous. Dispatched service tech Charles Gamez when directed by my home warranty provider. I alerted my home warranty provider at 9pm, the provider assigned Bill Richards Electric LLC to the job and the very next morning at 8am Bill himself called me and arranged The tech to come by the following morning. FAST RESPONSE! Had a GFI that would not reset and had a dead Christmas light circuit. Charles was very courteous, professional, and methodical figuring out the problem. Fixed it handily and also provided some advice for a few questions I had on other related electrical matters around the house. Bill Richards Electric LLC is a small company which is GREAT because few employees make for high quality and excellent collective knowledge base. Will hire again for sure!"

Electrical FAQs, answered by experts

In the United States, home outlets support a standard 15 amps, but you can upgrade per outlet if necessary. Most single-family residential homes have a maximum overall amp rating, usually 100 to 200 amps. Very old houses may have less than 100 amps, but that’s rare. Large homes often come with amp services above 200 amps to support modern lifestyles.

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.

GFCI outlets should be clearly labeled with LINE and LOAD labels, with arrows leading to the proper terminals. The line terminals are typically at the top, and the load terminals are typically at the bottom.

While you might not need to put lights and outlets on separate circuits, some local codes may require that you use separate circuits. Installing a separate circuit helps prevent total darkness in your home when your receptacle outlets take on too much power and blow a fuse or trip the breaker. It also costs less and is easier to simply install a new circuit.

Different types of light switches include single-pole switches (the standard switch in your home), double-pole switches, toggle switches, three-way switches, four-way switches, dimmer switches, and more. 

A single-pole light switch controls the power to a single device, whereas two-way, three-way, and four-way light switches control lights from different locations, increasing the number of connections in the home.
