30 AMP OPS

[John Suter]

Morning Leroy,

Nowhere (in your posts) have I heard about your
having a 50 amp surge protector (I recommend external)
which can be the greatest protection for electronics
in your coach as it won't be only the relays which
will be cremated if you take a surge.

The 240,000 volt line crossing our property once
fell through the 240V house feed, scorching driveway
concrete and attic 2x8's, taking out virtually every
house appliance, but the coach was protected by a $400
surge protector and was unharmed. Best $400 of
insurance I ever purchased. Power company just
laughed when I filed a damage claim with them.
