If you strike out, try Hubbell. I had 50A / 220V 4-pin twist locks
in amplifier and dimmer racks for power distribution. Cable end and
surface mount were available.
Bring plenty of money.

Go to your handy dandy electrical wholesaler.
You want to get a fitting with a loop that fits into the Unistrut.
This is the point that will support the weight of the hanging cable.
Next you want a Kellums type cable grip that will grab the cable and
hook into the Unistrut fitting, leaving about a 2 ft pigtail where you
will attach a plug that will plug into the ceiling receptacle.
Doubt you will find any of this at Grainger or McMaster-Carr.
They are strictly an industrial electrical distributor items.
Well, it's all done and working fine now. I spoke with the electrician and
he told me what to get. I ran the EMT and wires and he hooked everything
up. It's hard-wired, so I'll have to use the circuit-breaker to shut off
the power, but the panel box is within view of the machine and it's not like
a table saw where you're putting your hands inside too often. Plus, there
is a safety switch attached to the hood, so when it's opened up, no power.
The run is almost exactly 100', so it took a bit of wire. All 6ga with the
ground being 10ga. Liquiflex from the overhead box to the machine and it's
all working fine. I'm going to bolt a piece of EMT to the planer along the
cord for 4-5 feet and tie the liquiflex to it for protection.
The electrician was really cool and did this on his lunch break for me. he
also let me use his company tubing bender each night, so I gave him $200 and
lunch for his time and help.
Thanks to everyone for the help (Lew & dpb). I appreciate it.
