NEMA is generally 460V nameplate, and is good for +/-10%. Three phase, four wires and three hot wires are the levels of voltage that can be found in this kind of . . If what you have is 400 amps after balancing across three phases then total VA is like 144000, which is over the100 kVA transformer you mentioned. In single phase, power is not delivered at a constant rate. 208V 3 Phase power has 3 electrical legs (phases) evenly spaced in a circle (360 degrees / 3 phases = 120 degrees) around a center (neutral). That kind of voltage is there to protect equipment from high load days on the grid. ***Reverse Feed Capable and for use with 3-Phase Source by connecting primary to any two wires of a 3-Phase System*** Volts AC . 4 kW (5hp) power converter, with input & output frequency 50Hz . 3 KVA, 1-Phase, 240 x 480 Primary Volts - 120/240 Secondary Volts, NEMA 3R, Shielded Isolation Transformer, Epoxy Encapsulated, 50/60 Hz. The 3phase is not designed for single phase application (the current load is aprox double for single phase vs. 3-phase so will de-rate the efficiency of the step down transformer as well) and not intended to supply power to a standard single phase service, as mentioned above would call your local power company to have service from the main . It can be found in old and rural installations. Feeding a 3 VFD from the output of another VFD will almost certainly be trouble. To get 480 you need two phase at any given time to give you 480 volts. The ampacity is a measurement that shows you the maximum electrical current a conductor can continuously transmit. At 120 VAC you would need in excess of 200 amp service, about 208 amps before we even consider the inefficiencies of whatever you use. Voltage between two Hot Phases = 120V x 2 = 240V (1-). SKU: ATO-PHC-015. Conduit knockouts for easy installation. 2> 124/240/208 Volts three phase. (Meter requires a Neutral.) AutoStart Add-On For Existing Phase Converters; Transformers.
