do receptacles in a commercial kitchen were the walls may be pressured washed need to be weather resistant and have an enclosure that is weather proof when the attachment plug is removed , also they must be gfci protected if 120 volts.
Not in a "wash down" area. Those covers leak too much when the walls are being washed down, the old type seal better under those conditions.If it's a wet location wouldn't you need an "in use" style cover whether the plug was inserted or not?
406.9(B)(1) ... Exception: 15- and 20-ampere, 125- through 250-volt receptacles installed in a wet location and subject to routine highpressure
spray washing shall be permitted to have an enclosure that is weatherproof when the attachment plug is removed.
It all depends on whether high pressure spray washing is equivalent to washing with the spray from a (high) pressure washer. :angel:I always assumed that high pressure washing was beyond typical washing hose pressure.
The code does not define "high pressure". I read the exception as applying where any type of pressure washing is used....of course the AHJ may not read it that way.I always assumed that high pressure washing was beyond typical washing hose pressure.
