If this was intended to be line to neutral it would be rated 277V, pretty popular in lighting. |

Wiring a 480V Single Phase Circuit
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. |

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. |

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 or poles. Two legs or poles is single phase when using equipment. -- for full context, visit https://www.homeownershub.com/mainte...it-538066-.htm |

Thay get the 3 phase motor going by raping a rope around the shaft and pulling before starting or using a capacitor on a phase to make another phase then 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 -- for full context, visit https://www.homeownershub.com/mainte...it-538066-.htm |

It is probably a277 or a 480 volt single phase motor You can probably wire those HVAC fan motor different ways. -- for full context, visit https://www.homeownershub.com/mainte...it-538066-.htm |

Wiring a 480V Single Phase Circuit
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

Wiring a 480V Single Phase Circuit
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

There is no such thing as a stupid question my friends. 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. |
