Im trying to find a HP rated cord cap and can't seem to find anything below $300. Where do you get yours? HP rated is necessary for a cord and plug connected motor controller correct?
I am installing drops for a Lathe, Mill and the haas i believe has a 5hp motor on it.
That 5hp motor is behind a VFD, its not wired directly to the plug so the plug isn't a motor disconnect. Are the lathe and mill cnc?
The mill feed goes right into an on off switch and the lathe has motor contactors in it but you are correct the haas has a drive.
What is the rating of the receptacles you want to use? You can't put a 30A receptacle on a 35A circuit even if the load is a motor.
Its time I demur to those with better code knowledge of this. Is a pair of connectors hanging in the air on the line side of a motor disconnect switch on the machine considered a motor disconnect that requires HP rating? FYI the horsepower ratings on hubbell twist lock connectors are pretty low compared to their current rating.
Yeah that was one of my original questions and feared that might be the answer. I'm starting to think dropping a conduit onto a pole and feeding the panel that way might be the way to go.
yes and it be wired with a permanent method.
I have ran drops from 1900 boxes ( what you call 4" square boxes ) by using a Kliems basket strain relief cord connector that has two eyelets that I either attached to the beam or piece of secured unistrut. I would rather use a female twist lock cord connector rather then hang a box on any cord drops. I always used at least SO ,SOW or other heavy cord. Even if I was doing a 120 or 240 volt drop always used cord rated for 600 volts. Burned me up when I came across somebody that used cheap SJO cord for a drop. If I came off a FS or FD box with hubs that were parallel to the floor would screw in a steel 90 degrees fitting that had a 1/2 or 3/4" female threads connection and attach a Klien basket strain relief cord connector into it. Had a 225# apprentice hand off a 10/4 cord drop and it held him. At a factory that moved machines on wheels would install a heavy spring that would stretch a few inches to help peop!e from pulling female cord connector off cords that they neglected to unplug before moving.
