Tankless WH Receptacle Cover Plate

[Aaron Miller]

Exterior wall-mounted tankless water heater. Receptacle cover plate required to be listed and rated for damp area? In-use type?

[Jerry Peck]

That receptacle outlet is required to be:
- listed and identified as weather-resistant (WR)
- listed and identified as tamper-resistant (TR)
- GFCI protected
- and if that enclosure is not a raintight enclosure, then the receptacle outlet also needs to have a bubble type cover for it (was there a door over that area, or was it open?)

That looks recessed into the wall, is the proper wall insulation R-value in the wall behind it?

That water heater is bottom fed, does it have an atmospheric vacuum breaker installed?

Is that cord rated for that use?
