To prevent a plug from overheating, always ensure that the electrical load connected to the plug does not exceed the plug's capacity. If the plug feels hot to the touch or emits a burning smell, immediately shut off the circuit breaker and unplug all devices from the hot outlet. Prevent electrical fires by avoiding using extension cords or adapters with the plug, as they can cause it to overheat due to increased resistance. Additionally, ensure that the plug is properly inserted into the outlet and that the outlet is not damaged or loose. 

GFCI stands for Ground Fault Circuit Interrupter, a standard safety addition to home power outlets. In rooms where moisture is more likely, like the bathroom and kitchen, GFCI outlets stop the current when certain kinds of shorts are detected, preventing shocks. Both GFCI and the similar AFCI (Arc Fault Circuit Interrupter) outlets are polarized and have clear indicators on the receptacle where hot wiring should go.

You should never unplug or touch a buzzing outlet. If there are appliances plugged in that are causing the buzzing, wait until the appliance is turned off (or turn it off yourself) and then unplug it from the outlet. Test the outlet by plugging in something that won’t use much power—a small lamp works well. If the outlet still buzzes, have a pro investigate why.

Yes, dehumidifiers use a lot of electricity. However, proper humidity also means your home’s temperature remains more stable, thus lowering heating and air conditioning bills. The good news is you shouldn’t need to use a dehumidifier more than a few months per year, so the energy costs won’t be as noticeable as other larger appliances.
