The neutral bus in a Jandy sub panel melted. Was replaced by others. Then melted again. Then we were called. I personally have not seen it yet, but I trust the source describing it as melted. This panel feeds all the pool equipment. The HO says the problem only happens in the rain. No breakers tripped. The neutral supplying the sub panel was checked and is tight.
Any ideas of what could cause this? Could the neutral wire between the main panel & sub be damaged? Maybe shorting to ground?
Related?.... There is no cold water bond and the #6 copper ground wire ufer was very loosely connected to the #4 from the panel.
