Why does the reset button keep popping out?

If too much power is flowing through an outlet—say, because a device has fallen into water—the power is automatically cut off, and the RESET button pops out. Test monthly. d) The switches are called GFCIs: Ground Fault Circuit Interrupters.

How do reset buttons work?

Hardware reset buttons on PCs work by pulling the reset line on the CPU, which resets it and causes the computer to reboot. Unlike Ctrl+Alt+Del, pressing the reset button causes the BIOS to perform the POST check.

What is a GFCI and what does it do?

The ground-fault circuit interrupter, or GFCI, is a fast-acting circuit breaker designed to shut off electric power in the event of a ground-fault within as little as 1/40 of a second. However, it protects against the most common form of electrical shock hazard, the ground-fault.

How do I know if my hot water heater is working?
