Sewage Ejector Pump needd GFCI?

[deckscrew]

We installed a sewage ejector pump system. The pump has a sealed cord that plugs into a 20 amp/250v single receptacle. The receptacle and pump are located on the outside of the building.

Does the pump need to be protected by a GFCI breaker?

Thanks

GFCI required for 125V receptacles. No GFCI requirement for 250V.

I don't see anything requiring it in 2008 NEC 210.8

Yup, the 250 volt removes the GFCI requirement.

That's because 240 is safer than 120 LOL

I think that Jim knows that anyone could unplug a 120 volt plug and plug in something else. That's not going to happen if the receptacle is 250 volts.

are you sure about that ?

Thank for the replies. The 2 pole 20 amp GFI breaker looked like a tough item to find.

Why would a 240 receptacle not require a GFI while a 120 does?

In general, the probability that a person might be holding, or otherwise touching, a 120 volt device, at the time it experiences an internal failure, is a vast great deal higher than the probability that a person might be holding, or otherwise touching, a 240 volt device, at the time it experiences an internal failure.
