Arhi tipped us off to a potential problem in cheap surge protection devices. The metal oxide varistors (MOVs) found in surge protectors are prone to catching fire in cases of extended current surges.
MOVs are designed to suck up short surges that might occur on power lines. Unfortunately, in case of prolonged surges MOVs break down, usually causing a short circuit. This can lead to heat and possibly fire as shown above.
