I am programming an app for ordering 3phase heaters, and I have an argument to resolve with a coworker. Lets say I have a 208V 3-phase heater (delta connection), with a heating element on each leg L1, L2, L3. The total KW of the heater is 15 KW. My calculation for amps in each leg is 15KW*1000/[208V*1.73] = 41.7 amps.

For residential use, we may follow the same formula as above for single phase with taking the √3 (1.732) due to three phase power formula. Good to know: For the same load, the breaker size in three phase is less than the breaker size used in single phase AC circuits. Lets find the correct size of circuit breaker for three phase circuits as.

How do you determine cable wiresize? Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. 30,000 x 1.724 x 10^-8 = 0.0005172 ohm sq. 2..

Dec 3, 2016. #10. iwire said: Each set of phase conductors will have to total at least 1,200 amps the NEC allows a smaller neutral in some cases. For us a 1,200 amp feeder is often three sets of 600 kcmil copper. So that is a total of 12 - 600 kcmil (3A, 3B, 3C, 3N) and 3 appropriate sized EGCs for a 1,200 amp breaker.
Breaker size must be rated for a minimum of 125% of the full-load current of the motor it is protecting, rounded up to the next standard breaker size. For example, the full-load current of a 5 HP motor at 460V is 7.6 Amps. The breaker must be sized for 7.6 * 1.25 = 10 Amps. Therefore, it is good practice to size the breaker at 15 Amps.

But if you want the wire to cover 100 feet, you should raise the size to 4AWG. This is because you have to increase the amperage (by 20 percent) to compensate for the voltage drop. The more current you must transmit, the bigger the wire required. The voltage drops by 20 percent for every 100 feet.
