An Eco Smart Tankless water heater is installed with two or three 40 amp circuits. Two for the smaller unit and three for the larger. The installation instructions specify a separate EGC for each circuit. I saw an installation video on YouTube where the installer used EMT from the panel to the heater. Two 40 amp circuits with two EGCs. Any idea why a ground for each circuit it required?
