Dang! Blows my deal right out of the water! :eek: What Hubbell numbers are they? Look to be 3P-4W for 3-phase.

richey, they're designed to accept 8 to 4 gauge conductors.

I was thinking of using them with 8 or 10 gage S O wire. Are they to large of a connector for that? Will they work for three phase. I am not familiar with the connectors at all and cant tell from the photo how large they are. Duanne Im not jumping ahead of you am I ?? I am not sure it I can use them if they are too large. Murphy can you maybe make a photo with a tape measure by them or something to give me the idea of the size. Thanks Richey

what application do you need connectors for?

7A749 thanks for the information. Do these connectors use the center for a ground? Also do you know what size box the female connectors go in for the mount to the wall? I really appreciate all your help. I am trying to get some of our stuff where we can plug and unplug rather than just operating it with a breaker. We are at the end of the power line with our shop and we have been pushing our luck with lightning strikes. I wanted to be able to disconnect everything. Richey

I dunno.... Depends on the voltage being considered.
(and of course the body's terminal/grounding paths)
It wouldn't be a good idea to wire 'em to voltage that's above their rating.

Higher voltages can 'flash' big time.
Nobody needs a 480v fireball in their hands.

Better reference manufacturer's data.

Voltage rating aside, current paths are very important too.
For example, if one of the terminals is bonded to the body, for grounding purposes, and if that terminal was incorrectly connected to a hot leg, energizing the body. Yah, that body too...


Best to rely on manufacturer's data.

They are 250v. I just looked at one I have.

None of these type ground to the body.
No offense Gavel, but I seriously doubt that exposed metal of a handheld connector would not be grounded.
It may not be obvious with a casual glance, but I'd bet my pay that in some way the exposed metal is connected to ground.
AND via that same path the exposed metal could be energized if the connector was incorrectly wired.

That's why this stuff shouldn't be connected by guess and by golly - manufacturer's data.
Or at least "meter" it before recommending.

The specific Hubbell PNs haven't been given and the photo isn't clear enough to make out but they look like a CS8365C plug http://www.stayonline.com/detail.aspx?id=6275 and CS8364C connector http://www.stayonline.com/detail.aspx?id=6281 which ground thru the metal portions of their bodies with the three prongs for 3-phase power.

The ones I have up are for single phase 250V and do NOT ground thru the body but rather the dedicated ground prong leaving the other two for hots.

The company I worked for used both versions depending on the equipment being powered and Hubbell also has 480V rated pieces in both single and three phase.


Either way, looks like Murphy's law has them sold.
