Anyone know what type of electrical connection this is?

We stayed at the Route 66 RV Resort and Casino last night as we passed through Albuquerque. Very nice park BTW and the location for the Meet in the Middle Ralley (which we are unable to attend) but I digress.

Anyone know what type electrical connection this is? It was on the electrical pedistal opposite of the normal 30 and 50 amp connections.

We used to see those before all the TV trucks went to cam lock.
I think it's a 100 amp three phase?
Possibly for entertainer's tour busses that have 5 ac units.

The label on the bottom is attached and copied here. Not sure which image is more readable on your computer/device/phone, but each one will appear larger if you click on it. An electrician would be better at explaining things.

N.B. the caution about an "acceptable grounding program."

Good luck,

Peter

It is a “pin and sleeve” receptacle. I have only seen them in an industrial setup like a kitchen or factory. Becoming more popular the last several years. However I have never seen one at a RV park. It surprises me that they have one as you obviously need a matching plug.

It’s a 4 pin 100 amp receptacle
Hubbell is the brand.

Yeah - I did a cursory search of the Eaton site and didn’t intially find anything and am traveling so can’t research. There were quite a few large buses there.. and forgot to ask when we were leaving.

we use similar receptacles for 480/3 phase 100 Amp (welding receptacles). Ones I'm familiar with has catch/keeper to secure plug in receptacle. Similar to what GMFL identified, just different voltage. Industrial applications have all kinds of weird plugs/connectors.

No clue why it's in RV park???

Yes.

Most tour busses run their generators 24/7 because they have no easy access to power. 20kw.
The plug goes in one way due to one pin smaller, and the male part has a ring that turns a quarter turn to lock.
We got away from those because a 100' power cable was impossible for one guy to lift.
The other possibility is they have shows recorded and the TV truck or uplink sits there.

Anyone going to “Meet in the Middle”?

We won’t be able to make it, but those going could ask.

Hi

Based on the ratings on the plug, it could have some pretty crazy voltages on it. I would not go near one without some real information on how it is wired. Since you need a nutty adapter anyway and they are mighty rare ... that's an easy decision.

How about just calling the park and ask them what it's used for.

It’s the power for a portable uplink for sat communication. They are the power source for television, data uplink vans and other such use. Medical MRI units also use the type of connection. Really good for frying RV’s

You will also see them used by carnivals but once connected are divided down to 220 vac for heavy motors and further for 110 vac.

Some beverage companies use a similar plug for 3-phase coolers on the trucks. TV vans use the 3-phase as well.

And miss out chatting it up with all you guys and gals? ;-0

I actually did. It’s a 100 amp connection for some class A busses that require it with multiple coolers, etc.

That is 1 grounded, 1 grounding (neutral), 2 hots (110 to neutral on each, or 220 between the two hots) just like in your house. I would be hesitant to use it without a meter to check it with first...if done wrong, it would get ugly in a hurry.
