I have a customer that has a Hearing Test trailer that has two Locations with Appleton ADR6044 Pin and Sleeve Male Inlet on each end of Trailer , with a tranfer switch for using either one to power up trailer. The rating of the Inlets are 60A 600V 4 Wire. The system on trailer is 120/240V Single phase. I am looking for the female Connector for the SO cord which I think is Appleton ACR6044. Would it be code compliant and safe to use this set up. Or should it require 250V devices
 
You could use a 600 volt plug but to make it more idiot proof maybe an inlet/plug with the configuration for 120/240 would be better. Why are the inlets 600 volts?
 
Not sure why they used 600V. Maybe all they had at the time. They had a cord set up to run this but left them outside and they were stolen. Having a hard time finding the female end for the cord
 
I would sugggest connectors meeting the IEC 309 standard, Leviton and Hubble have them, and likely would be less than getting the expensive Appleton plug. IEC 309 connectors are unique for voltage and phase, 30,60,100 amps and are interchangable between mfgs, sometime the Europeans are good at.
 
On the side, one might ask why they didn't use a single 240/120v CS connector at one end of the trailer; I'll guarantee that 30-40' of cable costs less than a transfer switch, and CS connectors cost less and are much easier to replace than almost anything with Appleton's name on it (good product, $$$$$$).

If it were me, I'd consider replacing the whole deal.

Sounds like a mobile facility that moves site to site, which would explain the double ended feed. Different locations may have the power coming in on different sides. If that is the case, changing the ends is going to piss someone off at the next location. Not enough info to say exactly what’s going on. I know they do that with mobile mri trailers.
 
I don't think there is an issue with this as long as they aren't using that connector in the building at 600V or any voltage other than 120/240. We used to use 600V plugs and receptacles for 208/120 400 Hz because they weren't used for anything else.

Changing any part of this requires that matching change at each location and the trailer. Are there other wired locations that are ready but they don't go to? It may be cheaper to use a different common 120/240 setup, but there are multiple locations to change so the total cost needs to be calculated.
