For the heck of it, I asked ChatGPT the following:

How much does a 30 horse power, 73 amp motor cost to run per hour at 220 volts?

It replied with this:To determine the cost of running a 30 horsepower, 73 amp motor per hour at 220 volts, we need to calculate the power consumption and then multiply it by the electricity rate.

First, let's convert the horsepower to watts.

1 horsepower (HP) is approximately equal to 746 watts.

So, the power consumption of a 30 horsepower motor would be:

Power (in watts) = 30 HP × 746 = 22,380 watts = 22.38 kilowatts (kW)

Now, we can calculate the cost per hour using the power consumption and the electricity rate. Assuming a hypothetical electricity rate of 12 cents per kilowatt-hour:

Cost per hour = Power (in kW) × Electricity Rate (in c/kWh)
Cost per hour = 22.38 kW × 12 c/kWh = 268.56 cents or $2.6856

Therefore, at 220 volts and assuming an electricity rate of 12 cents per kilowatt-hour, the cost of running a 30 horsepower, 73 amp motor per hour would be approximately $2.6856. Please note that actual costs may vary depending on the specific electricity rate in your location.

Now, I'm not an electrician, but $2.68 per hour just seems way too low.
Is that reply accurate?
