I have a rarely used garden pump showing below, just found out the power cord is damaged during storage. Can I use outdoor connector to reconnect it, Is it safe? Did I miss anything? Are there other ways to fix this? I would like to be able to use it again. It will be a shame to throw it away.
This part of cord will be exposed to the elements but never be submerged in water.
This happened to us yesterday. The plug for our electric fence controller corroded in the weather then overheated, melted, and shorted. It was actively on fire. By luck, my wife was standing not far away when it happened and unplugged the other end. Never tripped the 20A breaker.
Video #1 is OK, assuming the twisted assembly will be taped over. No tools required.
But it is a bad example for 120 volt AC devices where you would never normally connect a black and white wire together, these colors have specific functions for 120vac.
Easiest answer if you don’t need the full length, cut it there and put a new plug on.
If that’s not long enough, you may need some kind of waterproof/submarine joint. Some use a resin inside that hardens.
If you do the join yourself, loose connections are the enemy, and cause fires like above - where it doesn’t cause a short that would trip the fuse, but the increased resistance through the loose connection causes heat enough to burn. Twisting wires like the video above isn’t reliably good enough.
