"Matt and his team did an excellent job upgrading our electrical panel. He coordinated the work with National Grid, relocated the panel, labeled the circuits and tested all the work. I would highly recommend Dever Electric."

Electrical questions, answered by experts

Yes, tamper-resistant outlets are a safe and effective way to protect children from electrical hazards. They feature a spring-loaded shutter that blocks the outlet slots when not in use, preventing a child from inserting foreign objects. While they are the safest option available, it's important to note that few things can be considered truly 'childproof.' Children may still try to imitate adults by inserting a plug, so constant supervision around any electrical device is recommended. Tamper-resistant outlets are a much safer solution than childproofing covers, which can be removed by children and may pose a choking hazard.

You can have power but no lights if the light switch is damaged. A damaged light switch is often caused by regular wear and tear or loose wires. In addition, simple problems such as a burnt-out light bulb or an unplugged lamp could be the cause of not having working lights.

Yes, an AFCI (arc fault circuit interrupter) outlet also has line and load terminals, although it uses different technology than a GFCI and offers a different kind of protection. AFCIs monitor for internal arc faults, a type of wiring problem that can start an electrical fire.

Short circuits can cause significant damage to electrical appliances, bodily harm, and potentially death to humans. For this reason, they are a serious occurrence. If you’re unable to find and fix a short circuit on your own, you must reach out to a licensed electrician for help.

The American Wire Gauge system calculates wire size diameters using the complicated formula D(AWG)=.005·92((36-AWG)/39) inch. A simpler rule of thumb is that every six-gauge decrease doubles the wire diameter, and every three-gauge decrease doubles the wire’s cross-sectional area. On the other hand, wavenumbers are typically measured in reciprocal meters (1/m or m−1) or reciprocal centimeters (1/cm or cm−1).
