I have a question concerning a switch that will be submerged during a flood event. I believe I know the answer, but I want unbiased responses, so I'll hold my tongue.
I have a 120VAC control circuit wired with #14 sis cable. This control circuit is powered by a 1kVA 480/120 single phase xfmr. My wiring diagram does not indicate either leg to be grounded. I'm not saying that it is not, I'm just saying I don't know and the diagram doesn't show it.
The circuit is protected by two 10A fuses on the secondary side of the xfmr (1 per leg).
This control circuit has a pushbutton in it that is mounted on the surface of a junction box. The PB is a normally-closed component. This junction box will be submerged during the aforementioned flood. Additional components in the circuit are a motor starter and a TOL for the motor. The switch and the cables to the switch are the only components of this circuit that will see water. Al other components will remain dry.
My question is this, what happens to the circuit when the water enters the jbox?
