as long as you don't mind the extra time it takes.. my honey uses electrical tape on every connection .. alternates going straight around the connection and criss crossing it over the plug.. this way the water will stay out .. even with 4 feet of snow piled on... and melted.. every single connection was still good and we never had a short..
yes it is a total pain to tear down (last year it was almost spring before we could see the wires out of the snow) takes extra time but insures your connections will be water tight
I grumble unwrapping connections come thaw.. and carry a plastic shopping bag on my belt to collect zip ties & used tape.. but it's worth doing
