CS6364 Versus NEMA L14-50

Looking at transfer panels, outside inlets, etc....


For a generator to plug into, what is the difference between CS6364 Versus NEMA L14-50. The CS6264 seems to be more of the *genset crowd* preferred plug.

Both of those appear to be cord caps, not wall-mountable inlets. Also, both appear to be 3-wire plugs. Am I missing something?

I have no idea what the CS6364 is, but the NEMA is just a configuration for a locking device.

As near as I can find it has three prongs and a brass plate on the edge or outside that acts as a ground.

Actually, the equipment ground is via a pin/sleeve in the center.

Furd, that is what I first thought when I saw the pin but then I saw the diagram and mention of a brass plate on the side that grounds it. I'm sure your right, just wonder about the confusion on grounding.

Defintely confusion...... my Honda 10K service manual shows the center pin of the recp. as grounded but I don't remember the plug having a connection on the center pin.

There is no nema L14-50. The only LOCKING 50 amp 120/240 connectors are the CS versions. The CS stands for California Standard. The ones I am familar with ground on the side plates.

The outer brass on the CS 50a connectors is ground.

There seems to be no NEMA L14-50 devices anymore. I found info on them earlier. Apparently that is old info that hasn't been updated.

Thanks for the catch.

From what I've read over the years when I was selecting a plug and socket for my compressor, some manufacturers labelled their higher amperage connectors as NEMA, even though NEMA itself never defined standards for those connectors.

I just went with straight plugs. The 6-50 I use is tight enough that it's not going to come out by itself. I wouldn't be afraid to try a straight-pinned 14-50.

Got it. Learn or wither on the vine!
