I don't install but I do some low-end PLC programming for an area EC as his employee. He took over some customers after I retired.
The system in question ran for several weeks before it started odd behavior. The difference being dry weather that turned wet. A cord and plug connected control station had been extended via another cord connecter/cap. That connection had gotten wet and muddy. PLC inputs trigger easily.
120-volt inputs. I made some logic changes and suggested to the customer he protect connections from the weather.
Even though it is a twist lock receptacle I am of the thought that it needs to be GFCI protected.
Yes/No?
