A couple of weeks ago, DW and I spent the weekend at one of our favorite camping spots. When I connected the power to the fiver, I noticed that the cable going into the connector felt "loose". We immediately started having problems, one which I suspected the campground still had an "open neutral" problem. However, as I troubleshot the problem, it became worst. Half the fiver did not have electricity - basically one side of the breaker box. As power was present at the park's connection, I suspected the power cable connectors.
Wow, was I correct!
This weekend I pulled the covers off the twist connector for the fiver and felt that growing panic of what could of happened! Inside the connector, the white neutral wire was completely loose within the connector body. The hot (120 VAC, 50 amp) red wire was barely hanging on the lug connection about a centimeter away from the loose neutral wire! I could only nightmare about the arc, heat, and destruction that could have been caused by those two wires meeting before the park's circuit breaker tripped!
That is when I started looking closer at the connector and wire. (Note: This is NOT a Keystone problem, rather a Keystone supplier problem!) The cable manufacturer had stripped the exterior insulation back way too far and had clamped the strain relief lock on the four individual wires! After only a little more than a year of use, the wires had wiggled enough slack in the strain relief lock to render it useless. Just the weight of the power cable hanging from the fiver was enough to slowly pull the individual wires out of the connecting lugs! That doesn't even account for the strain placed on the connector by the process of connecting/disconnecting, dragging to storage, handling, etc.!
Check your power cable at the connector! Does it feel solid? Does it move back and forth any or does it seem well clamped in place? If it moves easily or doesn't feel solid, check it out or have it checked out.
