Electrical FAQs, answered by experts

Yes, the National Electrical Code reviews household codes every three years. However, that doesn’t always mean that kitchen counter outlet requirements will change, but it does allow room for professionals to make updates. That’s why many older kitchens are no longer code-compliant thanks to changing rules for amperage, GFCI protection, and more.

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches often result from loose wiring, exposed connections, or other electrical problems that can cause overheating or sparking. Warning signs include crackling, popping, or hissing sounds when you flip the switch, which indicates live electricity that could ignite nearby flammable materials. If you suspect your light switch is faulty, immediately turn off the power at the circuit breaker and contact a qualified electrician to remedy the issue.

Most household circuits can handle about 70 strings of 50 standard mini lights, or up to 600 strings of LED lights, which consume less power than the incandescent variety. Make sure to factor in any appliances also running on the circuit.

Typically, when a 3-way switch only works when one switch is on, this is one of the most telltale indicators that the switch has gone bad (although this could also be the result of faulty or loose wiring). To diagnose the issue, toggle each switch until the light comes on. Once it’s on, toggle each switch separately again; the switch that doesn’t turn the light off is the bad switch. 

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.
