Typical full load current, minimum wire size and conduit size for 230V and 460V three phase electrical motors: 1 hp (English horse power) = 745.7 W = 0.746 kW = 550 ft lb/s = 2,545 Btu/h = 33.000 ft lb/m = 1.0139 metric horse power ~= 1.0 KVA.
Howmany amps are in a single phase heater? A coworker is arguing the following: Each element is producing 15KW/3 = 5 KW per element. Treating each leg separately, one can treat it as a ‘single phase’ circuit with 208V across the element. So amps per leg is 5 KW *1000/208V = 24 amps.
Eachof those three circuits provide 100 x 120 = 12,000 watts for 36,000 watts total. You mentioned 0.8pf, but conventional incandescent fixtures would have 1.0 pf. If you have been told that the fixtures are LED fixtures with 0.8 pf, the power available would be 0.8 x 36,000 watts. If 100 amp, 120/208 volts, 3-phase is available from a single
Amps(AC single phase) to kW formula: P(kW) = PF × I(A) × V(V) / 1000. Power (P) in kilowatts equal to Power Factor (PF), multiplied by current I (A) amps, multiplied by voltage in (V) volts divided by 1000. Amps (AC three phase) to kW formula: Line to line voltage. P(kW) = √3 × PF × I(A) × VL-L (V) / 1000. Line to neutral voltage
Calculationof AC three Phase amps to Kilowatts Line to line Voltage P (kW) = √3 x PF x I (A) x V L-L (V) / 1000, which means that the power in Kilowatts is calculated by the square root of three multiplied by the power factor times the phase current in amps by the line to line voltage RMS. The results are then divided by 1000. Active(true or real) power (measured in kilowatts, kW) Reactive power - the nonworking power caused by the magnetizing current, required to operate the device (measured in kilovars, kVAR) The power factor for a three-phase electric motor can be expressed as: PF = P / [(3) 1/2 U I] (2) where . PF = power factor . P = power applied (W, watts) Equivalenceof kW to Hp for three-phase motors: How many kW are: Equivalence in Hp: How many are 0.1 kW 0.12 kW 0.18 kW 0.25 kW 0.37 kW 0.56 kW 0.75 kW 1.1 kW 1.5 kW 2.2 kW 3.0 kW 3.7 kW 4.0 kW 5.5 kW 7.5 kW 9.3 kW 10 kW 11 kW 15 kW 18 kW 22 kW 30 kW 37 kW 45 kW 55 kW 75 kW 90 kW 110 kW 130 kW 150 kW: Equivalent to 1/8 1/6 1/4 P= V x I Cos Φ for 1 phase load . Rated Load Current = P / (1.732 x V x Pf x Eff) I= 90000 / (1.732 x 415 x 0.8 x .99 ) =90000/540= 157 amp ~ 157 A. in ideal case 157 amp shall be current capacity of cable and if we look at the cable size chart we will find that for 157 amp the current rating cable size 70mm2 cable size would be perfect. Toconvert amps to kVA in a single-phase power system, you can use the formula S = I × V / 1000 where the amperage (I) is in amperes, the voltage (V) is in volts, and the resulting apparent power (S) is in kilovolt-amperes or kVA. On the other hand, for the 3-phase system, you can use S = I × V × √3 / 1000 for line-to-line voltage and S

4 How to convert kW to kVA in 3 phase? To convert kW to kVA in a three-phase electrical system, the formula slightly changes to account for the three-phase power. The formula is: kVA = kW/PF ×√3 × Line Voltage. Here, the line voltage is the voltage between any two of the three phases. 5. kW to kVA conversion for transformer

Toconvert 3-phase kVA (kilovolt-ampere) to amps (amperes), you need to know the line-to-line voltage (VL-L) of the 3-phase circuit and the power factor (PF). You can use the formula: Amps = (kVA × 1000) / (√3 × VL-L × PF). For example, if the line-to-line voltage is 240 volts, the power factor is 0.8, and the 3-phase kVA is 15, then the
