Electrical questions, answered by experts

Usually, a light switch goes bad due to normal wear and tear. Light switches are mechanical devices with internal moving parts. These parts make contact with each other, and, over time, the friction can wear them down, causing the switch to feel loose, arc, or fail to operate. 

That depends on your setup. If a circuit breaker already has GFCI protection, then everything connected to that specific circuit is being monitored. You don’t need additional GFCI outlets on that breaker.

However, if the breaker is not GFCI, then you should have GFCI receptacles for at-risk outlets nearby water sources, because they are not receiving protection. Breakers in a breaker box can vary between GFCI and non-GFCI. Look for GFCI labels on the breaker or try to find the breaker model number to look it up if you aren’t sure.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

If half of a string of Christmas lights is out, it is likely because of a single burned-out, loose, or broken bulb within that section. Long strands of lights often contain more than one circuit, so when one bulb fails, it can cause the entire circuit (or half the strand) to go dark. To fix this, inspect the unlit section and test each bulb to ensure it is tight and functioning properly. Replacing the faulty bulb or repairing a damaged shunt will typically solve the problem.

Usually, your house panel is one of the key components that must be replaced when upgrading your amp service. In many cases, you will also need to upgrade your meter base as well as other electrical components.
