You can tell if a breaker is GFCI by looking for a red or yellow test and reset button that you can press in and out. You’ll know if an outlet is GFCI if the red reset button is located in between the two pronged sections.

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.

You will need a permit for any electrical work that involves installing or replacing wiring, moving or installing new fixtures, switches, or outlets, hardwiring appliances or HVAC equipment, installing subpanels, and upgrading electrical service. You typically don’t need a permit to have an electrician replace an existing light fixture or electrical box. You can always call your local building department to see if your project needs a permit, but a professional electrician will be able to tell you. In most cases, your professional will pull the permits for you.

People who have experienced blown fuse have occasionally tried to fix the problem by placing copper pennies in the fuse box. While they are good conductors of electricity and can seemingly “fix” the issue,  they don’t protect against short circuits or fires. Putting pennies in a fuse box is dangerous—the best solution is to call a professional electrician to fix the problem.
