To calculate the amp usage, you can use the following formula:
Amp Usage = (Wattage / Voltage)
First, find the wattage rating of your dryer, usually listed on the nameplate or in the user manual. Let’s assume the wattage rating is 5,400W.
Next, plug in the values:
Amp Usage = (5,400W / 240V) = 22.5A
Based on this calculation, the dryer uses approximately 22.5 amps of electricity.
