Where can I find a LR -14 30 amp generator cord and inlet box?

I'm looking for a LR -14 30 amp generator cord and inlet box for my Generac XP8000E. I'm afraid to let my electrician provide since he will mark them up significantly so I was going to buy the parts myself. However, everything I see online says rated for up to 7500 watts. Where can I find one that can handle my 8000 watt generator.

Thanks

You can't. 30 amperes (the rating of an L14-30) is 7200 watts at 240 volts. Yes, that means that at maximum output your generator is overloading the receptacle. This will be true of ANY L14-30 interconnect.

Just get the L14-30 cable and inlet that suits your purposes.

That's one problem with larger portable generators. You'll notice the 30A receptacle on the gen is fused/breakered at 30A. So even though the generator can power 8000w running, you can't actually use all 8000w. I assume they expect you to use 7000w from the 30A receptacle then 1000w off the 20A receptacles.

Granted, you probably will never know the difference - I just installed a similar 8000/10000 gen using the 30A output and it's been doing just fine.. *shrugs*

I was hoping to power a 2 ton central ac unit with the generator as long as nothing else was on but you are telling me that I will only be able to send 7k to the ac unit? I don't see how anyone runs central AC with a portable then regardless of the wattage on the generator.

Also where is the best place to buy, should I buy online or just go to Home depot or just get it from the electrician who is doing the install?

Thanks

The best advice if you need AC during an emergency is buy a 8000 BTU window AC that you can use to cool one room. You can get one for a lot less then the cost of a generator to run a central AC.

I still have the window unit as a backup plan but already have the 8000 watt generator I figure if I can run the central AC great if not then I should have no problem running the gas furnance and other extras around the house. My question is how are people running portable generators to power the central AC with an interlock kit and a L14-30amp cable if the can only send 7500 watts to the unit?

I bet you a doughnut that you ac is protected by no more than 30 amp breakers, so you dont really need to worry about supplying more current than that anyways.
