Here we go!

Help! I just got the electrician out here this week to redo some power in my house for other things, and took the opportunity to have him run all I need out to the garage and install the RPC for me. The problem is that it appears the plug has been cut from the lathe! I didn't realize this until now, and he's ready to do the install. I don't have any manuals for this thing to grab a wiring schematic, though it appears to be wired through an Allen Bradley box. Does anyone know what I need to proceed here? He's asking for a diagram or schematic to know what parts he needs to use to connect the power, but I have no idea where to start. I plan to call the place I got the lathe from tomorrow when they're open, but since I took delivery of it so long ago, I'm sure I don't have much hope of accomplishing anything there.

There's also a "On/Off" switch on the A-B box that looks to take a key. I don't have that key anywhere in the box of accessories that came with the lathe. Anyone have any ideas?

They probably had it hard wired into a box. Does that cord come out of the A-B box? You might open that A-B box as it may have wiring diagrams on the inside of the cover. That could help the electrician figure out what needs to be done.
 
I got the box open- looks like the wires will need to be pulled, and a new set used to construct a new cord/plug to run to my outlets. There was a diagram on the inside. I sent him these photos- hoping it's not too much of a job to recreate a plug/cord, but we'll see what he says. I know, some folks are probably thinking that now is a perfect opportunity to run a VFD, but I want to run multiple units and don't want to install multiple VFDs, so RPC is the way I decided to go for it. Not the start I was hoping for, but with any luck I'll have this thing powered soon so I can see how much more of a project I have to get it operational, lol.

I'm still not sure what to do about that on/off key switch.

It should be obvious to any competent electrician, that L!,L2, and L3 would connect to the output of the phase converter, along with a ground wire attached to the housing ground terminal; The keyed switch appears to be in the on position, I assume that it would be connected to the control circuit of the magnetic starter, if it is not in the on position, the switch likely could be simply jumped.

You're in a major city, right? I would remove the key switch cover (label the wires and take pictures so you can re-install) and take it to an Allen-Bradley distributor and ask if they can get you a key (if you want a key switch) or a compatible non-key replacement. A good locksmith can make you a key.

It worries me that your Electrician didn't know how to connect it. Did he take the cover off larger A-B box? If not, he doesn't want the work. Get a new Electrician. YMMV.
 
Congrats on the new lathe...
Ok, As an Industrial Electrician, this is easy and straight forward. If your sparky is confused...Get a new sparky!!!
