A/c Unit required wattage

There might be a placard somewhere on the A/C unit that will tell you the amps required to start/run the unit. You could also plug it into house power and measure them with clamp meter.

An easy way to remember the formula is PIE or Power = I (current) x E (voltage).

The size and condition of the A/C unit will be factors in determining if the EU2000 will start the unit. I have a 13.5K btu A/C that my Yamaha 2400 will start/run it but I've heard others say the same generator wouldn't start their 13.5K A/C unit.

Voltage times wattage equals amperage.

So, if the AC unit draws 15 amps, then it is 15 times 120, which equals 1808 watts. But, (and that's a big BUT), the startup draw can be quite a bit more than the running draw, and generators can only handle a very brief access draw, if at all.

Actually you put it incorrect by error i'm sure. Wattage DIVIDED by Voltage gives Amperes. But your right on the money about the start up Amps.

If there is a tag or the like on the unit itself it should give you some indication of the Amps it draws. That will be running amps if its listed not start up amps unless it specifically states so.

Thx Fishing Hat! and Ranger

I think you meant p = e x I which is power = voltage x current

Voltage times wattage equals amperage.

Woops. On edit, it is voltage times amperage equals wattage. Can't believe I typed that wrong. Sorry.
