IF using a 130 V rated MOV, where does it get wired ? Do you wire
between 120 vac and neutral.... or 120 vac and chassis of equipment in
question ?
IF a spike / transient / glitch etc occurs.and MOV conducts..which path
do you want the fault current to flow through, the ground wire or the neutral
?
The only place the neutral and ground are bonded together is at the main 200A
panel. On my 100 A sub panel, the neutral + ground are NOT bonded, per the
electrical code.
Either way, the MOV is fused, so if it does fail shorted... the fuse opens
up. Also I use a neon / led wired between output of fuse..which is also
the input to the MOV...and neutral.
In normal operation, the neon / led is illuminated. IF fuse opens up, the
neon / led goes out.... telling me the MOV is doa.
Tnx... Jim VE7RF
