The answer to 'GFCI outlet hot to touch' is that a GFCI (ground fault circuit interrupter) outlet that is hot to the touch is a sign of a serious electrical problem that requires immediate attention. This could indicate a ground fault, short circuit, or other wiring issue that is causing the outlet to overheat.
Some common causes include a faulty GFCI, wiring problems behind the outlet, or a connected appliance or device that is drawing too much current. If the outlet is hot, you should stop using it immediately and unplug any devices to prevent the risk of fire or electrical shock. You should then call a licensed electrician to diagnose and repair the issue as soon as possible.
