Fan Was Causing GFCI Receptacle To Trip But Belkin Surge Protector Solved The Problem

GFCI, Surge Protector From Belkin, Humidifier

A GFCI (Ground Fault Circuit Interrupter) opens the circuit when the current difference between Neutral and Hot wire is over 4 mA. Couple of weeks ago what was happening that everytime I switched to different speed of the humidifier (motor inside), since it was an inductive load, it was cauing the GFCI receptacle to trip due to inherited nature of inductor (reactive voltage / reverse voltage /arching etc.); I was thinking to build the snubber circuit myself but then decided to first find and test the surge protector - the one shown in the picture above. Home Depot folks were not optimistic that it will work. There is nothing wrong in testing especially if you can return it. Bought one and later end up buying one more because it worked. I even did the stress test by switching to different speed levels faster; no tripping at all. Give it a try yourself and let me know how was your experience. Enjoy!
