Hi Chuck,

Best solution is an isolation transformer but they are not cheap. Next
best solution is a galvanic isolator. We have one on each of our
30A shorepower circuits and it is pretty effective.

Our marina has a problem at some slips with stray current. Some of the
boats are loosing zincs at a fast rate while others are not. Looking
for some help in trying to resolve this and what kind of equipment
will I need. Thanks. Chuck
