Electrical questions, answered by experts

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.

You should never wire neutral and ground wires together at a light switch. Not only is it unsafe, but it’s also incorrect. The neutral and ground wires perform separate functions in an electrical circuit and should never be swapped or wired together at a light switch, light, or outlet. 

Yes, a faulty or broken light switch can be a serious fire hazard. Malfunctioning switches, often due to loose connections, exposed wiring, or overheating, can cause sparking or arcing. If you hear a crackling, popping, or hissing sound when you use the switch, it indicates live electricity arcing inside, which is a significant hazard that can ignite nearby flammable materials. If you suspect your light switch is faulty, turn off the power to that circuit at the breaker and contact a qualified electrician to remedy the issue.

You can use a double-pole switch for a regular light fixture, but it's unnecessary and won’t be the most efficient choice. A single-pole switch works perfectly for standard lights. Double-pole handle high-power appliances that require both hot wires to be disconnected. Using a single-pole switch for regular lights is more cost-effective, simpler, and more common in residential settings.

When power is restored to your home, the transfer switch will return to utility power after about 10 seconds. Your generator will then run for a few more minutes to cool down before automatically shutting itself off. In most situations, your home will stay powered by the generator for at least five minutes, even after your power comes back on.
