The calculator is designed to accept the total line voltage and current of the combined three cables. The equation for the area of a single wire is modified to: A = \frac {\sqrt 3 I \varrho L} {V} A = V 3I ϱL. The factor of \sqrt 3 3 is needed to convert between the system's phase current and line current.
600Y/347v 3-phase 4-wire or 600v delta. Naturally, all the line voltages above are the product of the phase voltages x root 3 (1.732). This is a mathematical given, as the phase voltages are 120deg displaced from each other and are non-linear loads. For some reason, American and overseas manufacturers refer to the higher voltage as "575" volts.
Can you run a 3-phase motor on 240V? Yes, it is possible to run a 3-phase motor on 240 volts, but it would typically require a 240V 3-phase power supply, which is less common in residential settings. Most 3-phase motors in homes and small businesses are run on 208V or 480V 3-phase systems.
RE: Operating 380V equipment on 400V supply The 400 V were more or less a rule in the “380” V world for many years. It is only lately (relatively) that newer equipment are rated 400 V. There are still lots and lots of 380 V equipment that now run on 400 V. Incandescent lamps are usually the ones that die first.
A. N.K.’s reason for using an open-delta connected autotransformer scheme to change 480V, 3-phase to 380V or 400V, 3-phase is not appropriate. For example, the maximum kVA loading can’t be more than 58% of the bank’s total nameplate rating. If you exceed this limit, the transformers will overheat.
GoHz 480V 60Hz to 380V 50Hz Converter. GoHz frequency converter can change 480V 60Hz to 380V 50Hz, also can be connected to single phase loads. If the peaking current is 16amps (especially during starting time), a 15kVA three phase converter will be suitable, rated current at 20.8amps. But we think the price maybe too high for it.
Route the wires. Remove all power to the wires. Run all input and output wires to the contactor. These wires should be rated in the manufacturer information. Use wire strippers to cut excess length off of the ends of the wire, making sure that the wires are long enough to reach the intended contact.
230 volts motor - 3-phase : 2.5 amps/hp; 460 volts motor - 3-phase : 1.25 amps/hp; Always check nameplate information before designing protective devices, wiring and switch gear. Single-Phase Motors - HP and Full-Load Currents. A motor of a given rated horsepower is expected to deliver that quantity of mechanical power at the motor shaft.
On a 400 V phase-to-phase supply the motor windings are connected in delta (from the Greek 'D' or Δ). On a 690 V phase-to-phase supply the motor windings are connected in star or wye (from the American letter 'Y'). From trigonometry you can show that the orange lines in Figure 1b are \$ \sqrt 3 \$ times the length of the black lines.
