The wiring connection diagram will be typically on a plate nearby or a label on the inside of the terminal box. WebAug 30, 2007 · I. iwire. Moderator. It's very likely a 480 volt supply system and 490 volts is not that bad. The AC unit is labeled 460 but is designed to work on 480 volt supply system. They do not make Motors actually labeled 480 volts. Bob Badger. Construction & Maintenance Electrician. Massachusetts.

WebApr 2, 2024 · You can use it, but there are two ways to use it 1. When the motor operating frequency is less than: 50 380/480 = 39.6hz, the motor can meet the constant torque operation. At this time, even though the power supply is low, the constant flux of the motor can be maintained by changing the frequency year on year, so the maximum torque is … WebDec 9, 2014 · Subject: RE: When your motor says "208-230/460" volts.. Faunsdale, AL If you could get 480 volt supplied to your single phase 500 mcm feeder instead of 240, then you could effectively double the power delivered through that feeder to your bin site. The wire will almost certainly be 600 volt rated already, just have to upgrade on each end. nothing but thieves impossible orchestra

WebJun 21, 2013 · It is certainly true that the average voltage at the motor may be nearer 460 than 480, due to voltage drop in the wires, but in that case why not apply similar conventions to other loads. It is not usual to specify 460 volt ballasts for HID lamps on nominal 480 … WebThe voltage: 480 volts between any two phases. And 277 volts between any phase and ‘neutral’. There are also three phase and single phase motors. If the motor is a three phase motor the actual internal winding structure of the motor will be made differently compared to if it was single phase. WebApr 17, 2014 · Here's a basic rundown on wye start ∆ run, we'll use a 6 lead single voltage motor for simplicity. If the motor is rated at 460 volts, it has 3 460 volt windings, one per phase. If it's connected ∆, then each winding will have 460 volts, and it'll produce its rated HP at its rated amps. how to set up firewall rules
