"As a private real estate investor, we have a lot or properties and hire a lot of contractors. CJ electric was outstanding. He did what was asked, took care of the permits and took care of the project without us having to oversee him. He also a needed trust factor as we did this project by communicating from afar. Truly a pleasure to work with someone like this."

"C.J. was very professional, very skilled and did an excellent job installing two heavy chandeliers - one to replace an old one and one to be moved to center over the kitchen table. I was amazed at how he went about his job; he was very precise and very careful to get the job done right and to our satisfaction. I was also very impressed with this young man who not only did a great job but did it all my himself, prepped the site and cleaned it after the work was done. I would recommend him for any electrical job. Theresa A."

Electrical FAQs, answered by experts

Yes, you can connect two extra outlets (or more) to one outlet if the total load on the circuit allows for it. If you have a 15-amp circuit, electrical code allows up to eight outlets or light switches. But if you’re dealing with outlets in the kitchen and bathroom, you may not be able to have as many. Kitchen and bathroom appliances often need higher amperage. You can also change a single outlet to a double outlet by cutting a larger hole in the drywall and replacing the outlet with a quad receptacle.

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.

Amps describe the amount of energy that can flow through a circuit breaker. Every electrical device that’s attached to the breaker requires about 1.5 amps. While that equates to roughly 13 receptacles per 20 amps, using slightly fewer ensures that your circuit will always have enough energy for sudden power surges instead of tripping when one occurs. In general, 10 to 12 receptacles is recommended for a 20 amp circuit.

Running conduits through an exterior wall is an effective method for powering outdoor spaces. From gardens to sheds to garages and more, it can be important to have electricity outdoors. Using conduit, which safely covers wires outdoors, is an easy way to get power where homeowners need it.

The life expectancy of a home electrical panel is typically around 25 to 40 years. However, this can vary based on usage, maintenance, and technological advancements. Regular inspections by a qualified electrician can help determine the condition and potential need for replacement as your panel ages. Factors like overloading, outdated components, or wear and tear might prompt earlier replacements for safety and efficiency reasons.
