Can someone confirm this wiring please?

Made an acquisition today on some standing desks that have built in surge protectors. Am I correct in stating that the way it was wired in the office was on 2 separate building circuits feeding the 4 desk circuits? I didn't have access to the electrical room, but to me it looks like they used 14/3 to go to 2 separate 120v breakers or 1 240v breaker. The end of the whip has this label on it:

The actual whip wiring looked like this:

Well that’s some crazy ****. But you’re interpreting how they wired it correctly.

Someone had to use the available circuits at the time. I have seen many cubicle sets with 3 or 4 circuits, think I've seen a 5 once or twice.

What do YOU want to do with it?

Tag says red/black/pink/blue are hots, white and black-white are neutral.
Don't see the black-white wire, so its the other white.

If you just want to hook it up to a single circuit, 12/2
Connect all the hots, neutrals, grounds to the corresponding feed cable h/n/g. done.

If you want to hook it up with two circuits, 2 x 12/2
red/black/white to one cable, and pink/blue/white to the other cable, and tie all grounds together.
You'll need to determine which white goes with red/black and pink/blue pairs.

If you want to hook it up as a MWBC with 12/3
red/black to black, pink/blue to red, whites to white, grounds.

Thanks for all the replies. I had a spare tandem 15 breaker laying around so just kept it 2 circuits. Very happy with the setup so far

Are those powered assist tops?

Yeah they are standing desks from an office. Goes from ~24" up to ~45". I understand weight capacity would be lower than a stationary bench, but the idea of me only having to lift something fairly heavy to 24" and raise it up with a button to whatever I want is too tempting. I also don't tend to work on anything crazy heavy in my house.

Well that explains the oddball circuitry. Nice snag btw.

Especially considering the price

,If you are using a 15 amp tandem breaker, make sure you have two neutral conductors pulled. A lot of people think they can make a MWBC with a tandem, you can't.

Yup I have the desks right next to the breaker box, so the whip was actually long enough to just go straight into the panel. No wires pulled
