FAQ:
Q: How to calculate AMP load?
A: Add together the wattage capacity of all general lighting branch circuits. Add in the wattage rating of all plug-in outlet circuits. Add in the wattage rating of all permanent appliances (ranges,dryers,water heaters,etc.) Subtract 10,000. Multiply this number by .40 Add 10,000.
Q: What is the difference between an amp, Volt, and Watt?
A: Amps, volts, and watts are all ways of measuring different aspects of electricity. An ampere, or amp (A or I, for current), is the amount of current in a circuit, while voltage (V) is the strength of the current as it flows through the circuit, and watts…
Q: How to calculate three phase amperage?
A: Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.
Q: What is the relationship between amps and wattage?
A: Amps is the unit of current flow,while Watts is the unit for power Amps,when multiplied by voltage,equates to Watts Measuring amps is much easier compared to measuring watts Amps is applicable only to electricity while watts is can be used for other forms of energy
