MIGwelders require different amps based on different applications. For example, you might need a 3-phase welder that could provide between 300 and 600 amps of power for high-end, more efficient production. However, you might not need more than 150 - 200 amps to weld materials with lower thickness levels.
19200W To get the wattage, you have to multiply the voltage and amperage. For instance, you can calculate the wattage of a 10MM 40A cable in a 120V service if you multiply 120V by 40 amps. This gives you 4,800 watts. You cannot determine the watts unless you know the voltage and amperage.
ForThree-phase motors, when HP is known: Where, Voltage: The phase-to-phase voltage for a 3-phase supply. Rating: The power rating of the motor in kW. KVA/HP: Maximum value corresponding to the NEMA code.; Locked rotor KVA per Horsepower. The National Electrical Manufacturer's Association (NEMA) has designated code letters to classify motors by the rotor kVA per horsepower.
Maxyou can have is 63amps with MCB (Miniature Circuit Breaker) control. Or 80amps with a MCCB (Molded Case Circuit Breaker) control. This applies to either a single phase or 3 phase supply. Anything over the above limits will need to be CT (Current Transformer) metered. Looked at a Electricity box and 9 smart meters.
A480 to 208 is a 2.3 ratio. For a 45 KVA transformer the size of the primary side overcurrent device is permitted to be 70 amperes. The ampacity of the load side conductors must be a minimum of 1/3 the value of the primary side overcurrent device—or 23.34 amperes in this case—multiplied by the primary to secondary voltage ratio of 2.3.
Thus for DC and single-phase AC circuits, the formula to convert kilowatts to amps is: [1] I(A) = P (kW) × 1,000 V (V) The current I in amps is equal to the power P in kilowatts divided by the voltage V in volts. For example, find the current of a circuit with 1 kW of power at 120 volts. I(A) = 1 kW × 1,000 120 V. I(A) = 1,000 W 120.

Theabove 3 phase wire size chart for air conditioners shows the recommended wire size based on the air conditioner capacity as well as the maximum current of various three-phase air conditioners. For instance, a 5 ton ac needs 2.5mm2 or 14-gauge wire to safely operate given that its maximum current can go up to 15 amps.

Thecalculation formula for three-phase power systems. To calculate the amount of power transmitted first is the equation formula, also known as Ohms Law: P= 1.73 x pf x I x V pf refers to the power factor. I refer to the current in a circuit (in amps) V refers to the voltage (in volt) Applying the Ohms law formula to calculate Power Output
