You're too late. 13 years ago, Joshua was abducted by giant outer space alien gerbils. The Air Force was unable to catch up with the flying saucer and Joshua has never been seen again. It's feared that the giant alien gerbils used him as a sex slave then ate him. It was a tragic loss. O_o

If it really says 480 1P then you do use two phase conductors of your
3P. If this was intended to be line to neutral it would be rated 277V,
pretty popular in lighting.

I have a bowl feeder that we recieved from China that is single phase 480. The control unit has a black and white wire with a ground. It's not difficult to find 480 single phase on your transformer. In this case a header machine. If your transformer doesn't have a legible diagram, just find your single phase 480 by checking between the legs on the transformer. If it's fed by 480V 3ph you should be able to find it. I'm not an electrician, just an industrial maintenance guy, but I've had to do this many times as China doesn't wire their machines like American or European manufacturers.

On a 480/277 transformer you will be using 2 "hots". Typically they
will be the Brown, Orange and Yellow legs.
Gray will be the neutral.
The 277 circuits will be Violet and Gray by the normal convention
although it is not in the code.

I don't know what a bowl feeder is but if it has a motor, and you connect to 3P power, it will run backwards. You need to unhook it and reverse the legs. All my time in a factory I never saw that not happen.

It was so common in the computer biz newer machines had a reversing
plug in the primary power tub that swapped 2 legs. If this is a single
phase motor it doesn't really make any difference tho. You are only
using 2 of the 3 phases.

Yeah I saw that but I wasn't sure I believed it was 1P.

I can guarantee at least one motor that will run backwards on 1P though: my drill, if you're next to me and ask to borrow it.

Lol, i just wired some single phase 480v dope lights for a client.

You have a 3 phase service.not a 3 pole service but it is the same.your just
using 2 of your poles. The correct way to say that is 2 legs of the 3 phases

Thay get the 3 phase motor going by raping a rope around the shaft and pulling

drop that phase after full speed then dropping that phase. And at that phase
you dropped you will be getting 277 90 degree off of power companys sistem.
You can use that as another phase to make a 3 phase sistem

That's a great question and I'm glad you asked and paid enough attention to realize that it was single phase rather than terminating it 3 phase.for Single phase 480v just land the 2 hits and a ground. There is no such thing as a stupid question my friends

Why wouldn't you wire it similarly to 240 single phase?
Depending on where you're at in the circuit there should be four wires.
There would be an equipment ground and a neutral to handle the
unbalanced load, if any.
The equipment ground and the neutral meet in the meter or as close
as possible to it.
I can't see the original post.

If I have a 240/480 volt dual voltage single phase motor connected by 2.5mm 2c+e to an isolator and then just 1mm flex coming out with active, neutral and earth connected is it possible the power supply to be 480v or is it most definitely 240v

I assume you mean 2 "hots" which would be different phases (not hits) and then a third wire being a green ground connection (a total of three wires.

2 hots of the same phase would be like wiring-up switching devices where one wire is line and the other is load.
