Yes. You should always turn off the power to the work area before beginning, use a voltage tester to ensure it’s off, and wear protective gear, such as insulated gloves or safety glasses, to prevent risk of injury. Proper wiring and grounding techniques are also necessary to make sure the job is done right the first time and won’t harm any future homeowners. 

At a minimum, you need an electrician to inspect the house wiring after a fire. The electrician will need to replace damaged or melted wires. If the electrical wiring is old, about 25 years or more, you should rewire the house after a fire. Old wiring can increase the risk of another fire, so replacing the wires is the safest option.

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.
