I'm leaving now for job #1. But, this is what good posting in asa is all
about!
If there are no answers or incorrect answers when I return in 14 hours, I'll
take a shot at the quiz. Some of my answers will be scientific guesses
(SWAGs) and some will be complete WAGs.
I'm particularly interested in question #2. I don't have either pieces of
equipment, but I'm supposing that the isolator is a transformer that
completely isolates ship's power from land power via induction. The gfi
monitors the balance between lines and opens the circuit when an imbalance
occurs, so I'm wondering if a gfi might offer some protection against
electrolysis.

intended!):

b. 220 VAC line
c. Satellite dish
d. Phone line

2. Whats the difference between an expensive dockside isolator ($$$) and a
hardware store ground fault interrupt circuit breaker?

3. What's the one thing that can ruin your entire electrolysis prevention
setup?

a. Tying neutral and ground together on the boat.
b. Unbalanced third leg at the marina junction box
c. Adjacent boat having neutral and ground tied together
d. Each adjacent boat using the opposite side of the split 220V.

4. If your dockside isolator trips can you be electrocuted when stepping
aboard a steel boat from a metal dock?

5. Does water moving along a steel hull increase electrolytic action?

6. What is the airspeed of a laden swallow?

7. What is your favorite color?
