A single-family residence with a net calculation of 22,800 VA at 240v single-phase will have a feeder load of how many amps?

80 amps
95 amps
100 amps
105 amps

The correct answer is: 95 amps

To determine the feeder load in amps for a single-family residence with a net calculation of 22,800 VA at 240 volts single-phase, you can use the formula for calculating amperage: Amps = VA / Volts In this case, you take the net calculation of 22,800 VA and divide it by the voltage of 240 volts: Amps = 22,800 VA / 240 V Amps = 95 This calculation shows that the feeder load is 95 amps, making it the correct answer. Understanding this basic relationship between voltage, wattage (or VA), and amperage is essential when calculating electrical loads for residential or commercial installations. The reasoning behind choosing this correct answer lies in the straightforward application of Ohm's Law and principles of electrical loading, which are fundamental in ensuring safe and compliant electrical system designs.
