This is an item I added in August of '04. The Surge Guard tests
the shore power for over/under voltage, proper polarity, proper
ground before transferring power to the coach. After that it consistently
monitors for surges and spikes, over/under voltage and any other
power problems. If it detects something wrong it will cut power
to the coach before any damage can be done to the components inside.
$360.00 and worth every penny. The very first time I plugged into
shore power in an RV park after installing this thing, it worked
as advertised. Everything was working fine on a really hot day (106
degrees) when the power went off. Nothing. Zip. Went to work with
the circuit tester and kept trying to get power to the coach. Nothing
helped. It seemed like one leg of the power was missing. Checked
all my connections and they were good. Had checked the receptacle
several times and finally caught it showing 120 volts across the
2 hot leads. The darn pedestal connections were bad. Had the park
move me to another site and everything worked fine.
