Ya gotta help me out here. We have a running battle in another forum concerning devices that are submerged in ponds / aquariums etc (lights, pumps, heaters and such) Most all of these are non metallic in nature for the most part and come from the factory with a UL approved or CSA approval stamp on them for their intended use. Most all of these items have 2 prong plugs or 2 conductor wire.......
One group says that a 2 prong plug is unsafe no matter what if its used n water......other group dissagrees as it meets approval and if used according to directions of manufacturer etc it is perfectly safe.
GFCI protection is used in both cases........Just what is so hazzardous with 2 prong or 2 conductors w/GFCI as compared to 3 conductor w/GFCI when the object is not metallic in nature and no chance of becoming a path to ground by touching it on the outside is possible.....
I say that if it was not safe UL or CSA CE would not have put their stap of approval on it........Just looking over the past couple of days at numerous pond and aquarium pumps, heaters, lights, bubblers etc ..9 out of 10 had 2 prong plugs........My one large centrifugal pump came with a 3 conductor wire but its 115/230 VAC and has a metal framed motor, however my straight 115 VAC centrifugal pump with composite motor cover and housing came with a 2 conductor wire as did my submersible pump.............which also has a composite body as well. My small little giant submersible pump has a metal body and came with 3 conductor wire, but the newer composite body Little Giant came with 2 conductor.......so what gives.......
