Nettet12. jul. 2024 · A typical surge protector uses a component called a metal oxide varistor (MOV). When the voltage spikes, the surge protector effectively diverts that extra voltage to ground through the MOV … NettetA. When subjected to stresses above its ratings, an MOV can fail as a short circuit. If applied conditions significantly exceed the energy rating of the device, and current is not limited, the MOV may be completely destroyed. For this reason, the use of current-limiting fuses is suggested. Q. How do you select a fuse to prevent failure of an MOV?
NettetThe surge protector is also plugged into a brand new GFCI outlet which we had installed last year (no other electrical problems in the house afaik) I understand that if the thing I'm plugging in is drawing immediate current e.g. "turned on," the inrush current can cause a little spark through the air, but it seems to happen even with things I'm ...
