## Questions & Answers

**Q: For boaters...Is this well insulated and thick to help prevent electrolysis to the aluminum out drives etc. Many don't realize this is a big problem?**
A: This cord is well insulated, it's outer case is completly sealed. It is thick, molded PVC. The electrolysis you are talking about is more commonly caused by bad wiring in the boat, e.g. lack of a blocking diode or isolation transformer. Also from the incorrect wiring of either of those items and incorrect ground wiring. Don Casey's & Nigel Calder's books ( both sold here on Amazon) cover this subject very well.

Is cord is good quality and works perfectly on my boat with the new style bollards and ground fault protection that my doc has. Love these. Great value for the money. I ended up buying two of them.
