Quick Tips: Electrical Waterproofing

Originally Published in MotorHome Magazine

I use a dielectric grease compound each time I work on electrical connections that are exposed to water, road salts or corrosive environments. My towed umbilical cord is protected on male and female ends, and I’ve never had electrical contact problems. It improves electrical performance during adverse conditions such as rain, fog, salt spray and temperature extremes. Just fill any voids and coat connections with the grease, then assemble. There are several manufactures of dielectric grease available at a variety of stores. I purchased the grease from an electrical supply house. The grease is a bit messy, but it’s worth a couple of paper towels.
