Most branded outlet strips have MOVs for "surge suppression." MOVs on
branch circuits are well known to CAUSE destructive failure of equipment
powered from these outlets when there are interconnections between that
equipment and equipment powered from other outlets. The only good place
for MOVs is at the service entraince (that is, where power enters your
home).
Hi Jim,
Why would that be true? I can't understand any mechanism that would
consistantly increase damage because an MOV protected stip is added.
The function and wiring of MOV's is to clamp all three conductors together
during a surge.
The proper fix is to make sure common equipment has a common feedpoint. Not
to eliminate protection in the hopes reducing protection also reduces common
mode currents between isolated feeds!
I'll certainly continue to use MOV's and MOV strips on all of my equipment.
