My facility recently replaced a hot water heater. This is a 3 phase 440 Volt heater.
The original water supply to this heater was galvenized pipe. It has been replaced with plastic. I am of the opinion that it would be a lot safer to pull in a ground wire, rather than rely on conduit for grounding. This conduit has been there for over 30 years and we have had several roof leaks with conduit getting wet and corroded. What would be your recommendations for this?
