fire pumps

[rey-man]

Is there any rule or code that refers to fire pumps being submerged in water?

this is for the application of Fire pumps in Piers.

Do I need to consider the flood level or mean high water of the tide? thanks.

Forget the fire pump, just wait 4 the high tide to come in, that will put any fire out.

Yes, there is. NEC article 695 deals with fire pumps, and 695.12 (D) says all energized equipment must be 12" above the floor. That applies to a fire pump in a building, and I would guess the concern is that standing water could develop in the room with the fire pump.

I don't think that applies to your situation though. I would refer you to 555 - Marinas and Boatyard's, and specifically 555.2. I would expect that you would have to keep anything energized above the "electrical datum plane" - which is probably 2' above the highest tide.

I wonder how they do things at the Bay of Fundy with its tidal bore?
