3-phase: how to tell amperage/voltage?
Hi,
After an 8-month-long search, I may finally have found a space on campus for a forge. For my forge I want a hydraulic press, which = power hungry The room is shared by a bridgeport mill, a lathe, and a metal bandsaw, which I'm told run on 3-phase. I'm new to this. I know that with standard household power, all outlets are 15amp, unless one contact is turned 90 degrees, and then you know it's 20amps. I'll visit the shop again tomorrow or tuesday and examine it more closely. How do I tell the voltage and amperage of this 3-phase circuit, so I know how much I can load onto it? The press would benefit from a 5-10 hp motor, so I need to know if it could handle that power. How do I find out; are there specific plug types to recognize-- if you even use plugs? thanks! -Bernard Arnest |
