Hi, I am a new business that has ordered some electrical equipment. The first is a packing machine and the plug that the machine is being sent I have attached to this post. It is listed as 220v, 3 phase, 50hz but NEMA does not show this to be the same specifications. How will I make this work in the US? Should I ask them to use something else? If yes, what? I will be leasing a warehouse with high amps but as a non-electrically educated person I do not know how to proceed. I would definitely need an electrician. However, I want to ensure that I know what needs to be done. I have a second machine that is a 1000L mixer. They are telling me the specifications for the output is: 3p AC380v 50HZ. I asked for a picture of the plug as well. I don't yet have it but I would like to know what I must face once these machines arrive to my warehouse. Please can someone give me suggestions as to what to do in this regard?
