Figure 5 - Wiring Detail
Be sure to ground the water heater. The preferred way to ground is with rigid metal conduit between the main panel and the water
heater junction box with approved end fittings (check codes on the use of flexible conduit). If making a separate ground, a green ground
wire is provided in the water heater junction box. Replace the junction box cover and insulation after you have made the wiring
connections.
