Electrical questions, answered by experts

If you are having trouble determining the right breaker size for your water heater, it is a great idea to contact an electrician near you to help. They can help you determine the best option for your home and install the circuit breaker for you, ensuring that you have all the proper permits and that your circuit breaker won’t overload, which could lead to fire and other damage.

Yes, a hot or overheating outlet is a fire hazard and can cause a fire. An outlet becoming hot indicates an electrical problem, such as an overloaded circuit, loose connections, or a faulty component. The heat from these issues can ignite nearby flammable materials like curtains or furniture. If you notice an outlet is hot to the touch, turn off the power at the circuit breaker, unplug any connected devices, and consult a qualified electrician. If a fire does start, use a Class C fire extinguisher or baking soda to suppress it, or evacuate immediately and call the fire department.

You should always turn off a breaker whenever electrical work is being done. This step can prevent electrical shock and injury. Also, if a breaker is repeatedly tripping, it can mean there is an electrical overload, and it should be shut off. You should contact an electrician to figure out the cause. Make sure to review how to turn off your circuit breaker safely if you do it yourself, and follow safety precautions to avoid severe injuries.

Upgrading your amp service could possibly be a solution to tripped breakers. Circuit breakers in an electrical panel trip as a safety measure when something goes wrong with the current, and that’s often caused by plugged-in devices trying to draw too much current. Replacing the electrical panel with a new model and new breakers designed for higher amps can fix this problem.

The National Electrical Codebook indicates that there should be at least 6 inches of wiring in the breaker box for connecting purposes. When in doubt, err on the side more, because you can always cut some wire off but you can never add it back on, and if you don’t have enough you may struggle to finish wiring your breaker box properly.
