small generator for ac?

[TravisNuwa81]

Im picking up small 5th wheel. 27' 1985 Jayco. Will a 1400w generator run just the ac? Im wanting to do some work to the inside but its toooooo hot.

1400 what's will give you around 12 amps mine 15000 btu pulls right at 15 amps so just a little small but I do use a 10 gauge extension cord to use my washer plug on a 20 amp breaker

So do you think itll be ok if thats all I run?

1400 watts is not sufficient to run an air conditioner.

Since you need a brief surge of 5500 watts (locked rotor watts) to get the A/C compressor started, you will need a generator capable of providing instantaneous power if 5500 watts for about 3 seconds.

Nothwithstanding, that an air conditioner that has been resting for 5 minutes or so, and "decompressed" before applying power, may start with substantially less power.

You really have to check the specs for each.

Crud. Well then how could I go about getting 30amp to my garage? I have 110 outlets out there now. I can do electrical but need to know what I need to do it.

I can run a 13,500 btu A/C unit with my Yamaha 2400IS generator. 2400watts is enough to handle the surge of start-up if I start fan 1, then fan 2, wait 5 seconds then A/C low, wait 5 seconds thrn A/C high.

If I do not wait the generator trips it's breaker and needs to be reset.

Hmmm. This generator is only $60 and im trading tires so its essentially free. And he said its super quiet

If it's free, then you have nothing to lose. Except for your A/C compressor that is.

So are the 110 outlets on a 15 or 20 amp circuit? If 20 then you should have enough power to run the AC.

You don't need 30 amps in your garage; 15 amps is quite sufficient to run an A/C.

For the 50 amp startup, if you are using household screw-in fuses, then you must use a "slow-blow" fuse to accomodate the few seconds of high startup current. A standard fuse will blow before you ever get the A/C up and running.

If your house has circuit breakers, then they are "slow-blow" by default, so they will run an A/C without any modifications.

My powerpanel in the house as circuit breakers. If they trip need to flip them off then back on. Its either a 15 or 20 amp. So I just need my power grab converter to go from the 30amp plug to a standard plug and I can run my ac and everything???? Thats AWESOME!

Thanks for the link! My garage is wired with standard romex. Could I switch the breaker with a 30amp and then add the receptical?

You can NOT just change the circuit breaker with out changing the wire from the breaker to the outlet. I ran 8 ga wire to the garage, you can use 10 ga for 30A. If your circuit breaker is 20A then it is likely that 12 ga was used. A hard star capacitor may allow your air conditioner to work with a lower ampacity/watts but your 1500W generator is not likely to be sufficient.
