I am doing some hurricane prep. I have a wall unit Koldfront 1000w AC in converted car port. My Generator is a Firman dual fuel 10K with the same type outlet. I am looking an extension chord about 30 - 40 feet to run this AC if the power goes.

Anything I need to know, look out for? Or likely, as long as the plugs fit, I am good?

1000w


Voltage?

1000W @ 120V is 8.33 Amps

At 100 feet or shorter you will be fine with a 14 gauge or larger.

6-20p implies 240v w/o neutral.
It seems odd that such an obscure receptacle would be on a generator. I could be wrong or this could be a typo/misidentification.
Cord will likely need to cross to L14-30p or similar just leaving the neutral blank.
Please verify plugs and receptacles.
Koldfromt also has a 1000 sqft and a 10,000 watt but no 1000w. Please verify.

I missed that in the title. Current for 240 would be half for 120 assuming the OP has the right details. I'm assuming the 6-20P is the AC chord.

ETA: I assume this is the unit or an earlier version.

I missed the 6-20P in the title. I would go with 12 Guage wire since the outlet is a 20 amp outlet.

I re checked the outlets on the Gen The one that fits is listed at 120... There are 4 outlets . 2 of the others are 2... 14-50R 50A 120/240v, and an L 14-30R 30A 120/240.

I found an adapter plug on an "RV" shop page that converts the L -14-50R to 6-20R female, which should take a 6-20 P. So now 50 feet of extension chord...

Am I understanding this correctly?

Agree. 14 to cheap out. 12 correct and 10 if you want the breaker to protect the cord.
No way the generator has a NEMA 6-20R. That would just be weird. Probably has a 120v 5-20R which looks the same as 6-20p if both are facing the same direction but not if they face each other.
I assume cord needs 6-20R on one end and L14-30p on the other leaving the silver screw blank. These are just assumptions because there is more than just one missing piece to paint a full picture.

OK so that outlet on your generator is a 50 Amp circuit, you probably don't want to use that one. The 14-30 R is probably what you should use. The main reason I say this is because, for a 50 Amp circuit, you should have 6 gauge copper (4 gauge aluminum) to protect yourself from overheating the wire/causing a fire in the event of a short circuit. For a 30 amp circuit, you need 10 Gauge wire which is cheaper and much easier to work with.

Or use something like this which has a built-in 20 Amp breaker

and then use a 12 gauge wire extension cord that you either build yourself or buy like this one
