Can anyone tell me if a 14000 w generator will run everything on a 40 ft. Montana,2 ac's and everything else. 50 amp.
 
Sounds like overkill, our 5500 watt Onan on board generator will run everything in the unit that we need, but I have not had coffeemaker, hairdryer, electric skillet, vacuum cleaner, both air conditioners and the microwave going at the same time.;););)
Bingo
 
I've run our single AC and the big TV at the same time on just one of our Yamaha 2400is generators. You don't really even need 50 amp service unless it's really hot and you've a second AC and are running a lot of other stuff at the same time. Honda, Yamaha, Robin/Subaru and a few others make very quiet generators and there are even quiet diesel ones available too that are large enough to take care of anything you've got. Bingo's got the Onan propane one that works well.
 
That's more than twice what you need. At 50 amps you only need up to a 6000 watt or probably even 5500 watt generator. Look at the run rate ratings not the peak ratings and if a 5500 watt peak rated generator supports about 5200 watts of run rating then a 14,000 watt rated can probably support TWO rigs off this same generator easily, provided it had the proper connections (two 50 amp connections).

The disadvantage to this generator, is it high rating when in a campground and the fact that it IS overkill. The noise alone might draw unwanted attention or drive you nuts. There's also a possible concern with sensitive electronics inside your rig, but if the rig is connected to this generator, you might be okay. Comments from an electrical expert to discuss the cleanliness about the power sine wave will be warranted about now.

If it were me, I'd use that beast at the house as a backup and use smaller & cleaner power generator for the rig. To answer your original question, as far as power needs are concerned, this generator would have NO problem supplying the power. You would still need a bonded power cable and hope the power sine wave does no damage to the devices plugged in at the rig.

I currently use two Honda EU2000 connected in parallel which provides about 3300 watts of run rate or enough to comfortably run a 30 amp rig. If I wanted 50 amp, then I'd buy a triple connect parallel cable and add another EU2000 (6000 total peak watts or about 5000 watts run rate). If one currently has NO generator, then between 5500 to 7000 watt generator is warranted. 14,000 watts is WAY more than needed.
 
14000 should run everything you have and half the campground. I only have one A/C on my 3100 and I can run the A/C, microwave, coffee pot, ceiling fan, TV and all the lights with a 6500 Honda running at about 5500 watts.
 
I agree with the overkill. Two ACs running 15 amps each is only 3,600 watts. That leaves a lot of power for everything else.
 
My question would be where are you going to pack a 1.4kw generator. Are you sure your not talking about 1400 watts.

If it is indeed 1.4 kw then it will be major overkill, if it is 1400 watts then it will not power a lot but will sure power the essentials, but not the AC.
 
14000 watts? How big is this generator? It would be so big will it be cost effective to tow it around the county for a 5000 watt need? I have 4000 watt generator and support all my needs.
 
Thanks to all for the responses. The info is great, it was a good buy for the 14000 w, $1,200 new @ 58db & 228 lbs. I will look at something smaller with les watts.
 
I run the 3750 with a Yamaha 3000iseb for days. Can't run both 15,000 Air units, but has plenty of power even in 110 degrees. Ran it for two weeks straight last summer! I am more concerned with how "clean" the power being produced. My Yamaha is an inverter type. Keeps computers etc with clean steady power. Also is easier on the three flat screens . 51 Decibles outside, only 47 in my generator box!
 
Chuck don't forget about the noise that comes from that big of a generator. Unless you are in a very isolated area with nobody around and you're wearing ear plugs when you go to bed or unless you have some really good muffler system it will be way to loud for any camping set up! If you can get it for the Stick and Brick as a back up there it would be idea!
 
Rondo is right. We had a big construction style genny for home emergencies and when we did use it it plugged into our garage 30' feet from our bedroom. Even so we had to get used to the noise so we could sleep. Closer than that there would have been no getting used to it.
 
1.4KW weighing 228 lbs. Sorry. Got pictures or such???

Buy one or 2 Honda 2000Eu or such.

Gotta agree with Jim on the weight question, an internet search for 14000 watt generators only yields the construction type which all weigh well over 300 pounds.
Bingo
 
14kW generator for $1200 is a great deal. I have to agree with the other comments about the weight. My 7.5kW generator weighs around 200 lbs if not more. Wouldn't have to worry about running all the appliances in your house!
 
On this topic but nothing to do with the OP's question, how much does the Onan 5500 weigh?
 
Bingo, I think you're correct as we have the same genny.
For the size the OP is talking about would likely be a Trailer Genny and probably a multi-cylinder motor.
 
bobcat says it right... it's 14Kw, not 1.4Kw. 1.4Kw and 1400 watts are the same. 14.K watts and 14000 watts are the same.

It's hard to believe a 14KW generator is only 58db, but at 228 lbs maybe there's some insulation that makes it able to run that quiet. For only $1,200 that's a great price and sounds like it would make a great home power backup system. For me, I'd also have to pay someone to install it, too. There's a bunch of safety considerations that I know of but not how to install them and a good electrician would know what to do.

But I would not use this for my Monty.
