Electrical questions, answered by experts

If all of the outlets in one room suddenly stop working, it’s likely the result of a tripped circuit breaker. This easy-to-resolve malfunction is caused by overloading the circuit with too many working appliances at the same time. Locate the tripped breaker in your electrical panel and reset it to restore power.

You don’t need an electrician to change an outlet—but that doesn’t mean you shouldn’t hire one. Working with electricity can be dangerous, not only for you but also for your home and the members of your household. There’s the risk of electrocution, poor wiring burnout, and electrical fire. When you hire a licensed electrician, you’ll have peace of mind knowing that your electrical outlets are installed correctly and up to code.

Baking soda is an effective fire reduction method. However, flour and baking powder are very dangerous around flames. Flour is flammable and it can also conduct electricity. The combination can cause serious injury from electrical shock and worsen the situation by adding fuel to the fire. Baking powder is also not an option as it's also highly flammable. 

While you might not need to put lights and outlets on separate circuits, some local codes may require that you use separate circuits. Installing a separate circuit helps prevent total darkness in your home when your receptacle outlets take on too much power and blow a fuse or trip the breaker. It also costs less and is easier to simply install a new circuit.

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.
