A recently purchased power boat docked at the Hawaii Yacht Club caught on
fire,The fire department determined the cause to be a surge protector in the
engine room.As a marine electrician I have seen my fill of electrical
nightmares that look like electrical nightmares but these power strip surge
protectors do a good job of deception.If you need that many receptacles then
the electrical design is suspect.Since the National Electrical Code does not
apply to ships,boats and floating buildings and the Coast Guard CFR's apply to
"inspected" vessels,there are no boat police to make private boats comply with
safe wiring practices.A responsible marine surveyor that addresses the
electrical status of a boat is the only driving factor I have seen work since
insurance companies listen here,Back to the protector:the MOV's inside the
device protect Downstream loads.Upstream the circuit breaker should trip
provided the fault is not on the neutral side(hence reverse polarity regarded
as a warning).Marine Electrical Services.Comments to: Steve Medley,
