"Scott did an excellent job for us. We needed an EV charger installed and a few other things done. He came by, sized up the job and gave us an estimate. In a few days he showed up ready work. He installed the EV charger, re[laced 4 thrmostats, and fixed a doorbell. All went well. His price was reasonable. He worked quickly and efficiently and got everytjing right the first time. I highly recommenr Moses Electric and would glady hire Scott for future electrical jobs."

Electrical questions, answered by experts

Yes, you can put a dimmer on a three-way switch, but it can’t be the same kind of dimmer you’d put on a standard light switch. A three-way switch requires a three-way dimmer. If two switches control a single or multiple lights, then you need a three-way dimmer. The type of light bulb should also be compatible with your fixture and dimmer.

The main types are 15-amp 120-volt outlets (2-prong and 3-prong), 20-amp 125-volt outlets, and 240-volt outlets for large appliances. Safety types include GFCI, AFCI, tamper-resistant, and weather-resistant outlets. Convenience types include switched, combination, USB, smart, and rotating outlets.

Old electrical systems may have more problems than newer ones. In some cases, like if your home has aluminum wiring, it may be necessary to update your electrical system. You should also update your home’s wiring if it still has knob and tube wiring, which is considered dangerous by modern building standards. If that applies to you, get in touch with an electrical professional near you to obtain a quote.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.

No, there aren’t additional code requirements for kitchen lights. Kitchen lights and other electrical circuits in the kitchen have different code requirements. Outlets need to be particularly robust because of their frequency of use and proximity to liquids. If you need help determining where to install outlets in your kitchen, consult a local electrician who can ensure that placement is functional and up to code.
