Code-accepted or not, one alternative substitute to a receptacle and male cap on SO cord is a female connector body on the SO-cord opposite end mated with a locking-style ‘flanged inlet’ or ‘motor flange’ mounted on the utilization equipment.

Yeah, but typically you won't have a fixed cord with a female connector but an extension cord. That practice is pretty common for European garden appliances and larger 3ph stuff like table saws, etc.

Here is the rest of the story!!

I have never seen these units installed correctly, and that pump, tank and control box never gets bolted down.

So how about it Joe, would you approve flexible cord for this installation?

iwire:

If I was asked to inspect this type of installation I would want to find out if the unit came with a cord cap, or if it was designed to be connected as shown.

I see were the entry was in the bottom at one time, and I will bet that some vandals pulled, or bent the fitting at the end to break the concentric out?

If an electrician was to use conduit or EMT it would not be difficult to terminate into a box, and receptacle that would be a better method like BJ suggested above.

It's been this way for as long as I have been in Boston, going on 25 years!

I think the OD-green cord ends are usually called ‘MS connectors.' [mil-std] Their very limited internal creep and strike dimensions {clearances} usually make them an awful choice for any outside AC-power or –control circuits.

Bjarney, Those are supply and return hydraulic lines with quick connects.

There is no electrical in the "big box" all electrics are mounted to the tank pump combo.

These units are a sore spot with me, our plans will call for a disconnect located outside for a trash compactor, then a non-electrician will come and "install"his pump unit without any concern for the NEC.

This one is a basic install but some are much more elaborate with the pump unit outside but a set of controls placed inside the building near the trash chute.

The common wiring method will be flexible cord or LTFM supported with a few tie wraps often with a hydraulic line for a pressure gage tie wrapped to that.

I would like to have inspectors shoot these down but often it is done after our final.

Oops, iwire — I screwed up big time. I used to have to deal with those at 480V, and the reason was that they were cheap compared to pin-and-sleeve connectors.

Regarding iwires point several posts back about 400.7(A)(6) not being correctly applied, I was wondering if 400.7(A)(7) "Prevention of the transmission of noise or vibration" applies?

On the (very few) compactor installations that I've seen, there is invariably some form of weatherproof flexible whip between the disconnect and the pump enclosure.

Nice looking lug that the white wire terminates at in the disco.
