Question

a 5.4-kva, 240-volt electric clothes dryer will contribute ______ amperes to the neutral load, when calculating the service by standard method

Answer 1

To find the contribution to the neutral load of a 5.4-kVA electric clothes dryer operating at 240 volts, divide the power by the voltage, resulting in a current of 22.5 amperes.

Step-by-step explanation:

To calculate the current contribution to the neutral load by a 5.4-kVA, 240-volt electric clothes dryer when using the standard method, we apply the formula Power (VA) = Voltage (V) × Current (A). We rearrange the formula to solve for the current: Current (A) = Power (VA) / Voltage (V). Plugging in the numbers provided:

Current (A) = 5400 VA / 240 V = 22.5 A

Therefore, the clothes dryer will contribute 22.5 amperes to the neutral load in an electrical service calculation.

Answer 2

A 5.4-kVA, 240-volt electric clothes dryer will contribute 22.5 amperes to the neutral load when calculating the service using the standard method.

Step-by-step explanation:

To calculate the current contribution to the neutral load for a 5.4-kVA, 240-volt electric clothes dryer when using the standard method, Ohm's law and the power formula can be applied. The formula for power (P) is P = VI, where V is voltage and I is current. Therefore, to find the current (I), you would rearrange the formula to I = P/V. Given a power of 5.4 kVA (which is equivalent to 5400 VA) and a voltage of 240 volts, the current on the neutral wire would be I = 5400 VA / 240 V = 22.5 amperes. This means the clothes dryer will contribute 22.5 amperes to the neutral load.
