No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

No, both switches do not need to be on for a 3-way switch to work. When the two switches are in opposite positions, the circuit is open and the light is off. Flipping either switch closes the circuit and turns the light on. So, either switch can turn the light off independently, and both switches do not need to be in the same position for the switch to function.

The average cost to hire an electrician is around $350. However, every electrical job varies in scope, materials, and labor involved, so while you will likely pay anywhere between $85 and $1,100 for standard jobs, a project like rewiring a house can cost up to $30,000. You might also pay slightly higher prices if you need emergency work done or if the work involves accessing a hard-to-reach area in your home, like an attic or cramped crawlspace. You should ask your electrician for an estimate before agreeing to the work.

If the outlet is a GFCI model, this is normal since these outlets have their own breakers that shut off when they encounter a problem—just hitting the reset button should solve the issue. Otherwise, the outlet could have bad wiring, or your circuit breaker could be having issues. If the issue started out of nowhere and is not on a GFCI outelt, it’s best to contact an electrician to diagnose the issue.
