Generator to power TT.

Yes, you can re-wire your trailer for 240VAC and use your generator much more efficiently.

The answer depends on the generator.. SOME do have two coils, and a switch, and a 30 amp 120 volt twist lock and a 30 amp 240 volt twist lock.

Some do not

However this applies.. IF you try to connect both legs together on the 240 volt (4 prong) Twist lock.. You may not like the result, which can range from a tripped circuit breaker to a destroyed generator..

But if you have a 30 amp 120 volt twist lock.. Just set the switch to 120 and let the generator do the work for you.

You can get the proper Generator to RV adapter at any Major RV delaer, Generator store or Camping World.. Might even find one at Wal-mart et-al.

Without the air a single Honda 2000 should work fine.

X2...

Or, you could purchase a 240-120 VAC step down transformer, connect to the generator 240 line, and connect the camper to the 120 line, and this would balance the generator load...

can you provide a business that sells this stuff?
in Cleveland or Akron Ohio????

Thanks.

Not sure where to find locally, I'll leave that up to you, but something like this would work -> 240/120 VAC, 7.5 kVA, Transformer

Clearly you MIS-READ my message.. there is a period at the end of "cable/circuit"
the 7000 watt is my generac..
so I have NO IDEA what you are talking about.

the Honda UI/inverter models only put out 120v
parallel increase the watts, DOES NOT CHANGE THE VOLTS
AS FAR AS I KNOW
no Honda std synchronous (non inverter) generator that has 240v option can be paralleled
when you parallel Honda UI gensets, you increase the amps, never the volts
to increase volts the generators would have to be 'IN SERIES' LIKE TWO 6V BATTERIES equal 12v

i don't remember reading about any 240v parallel option with honda generators

I see Honda has a setup to connect 2 generators together using a parallel cable/circuit.

7000 watts at 240 volts OR 3500 and 3500 at 120 volts.

so it is not possible to get 7000 watts at 120 volts..
but 7000 watts at 240 volts.

So I can NOT use this generator to power my TT as I can only use one side...

as posted at the top my TT has a 3 prong 120 volt @ 30 amps.

Thank You for your help.

A 240 volt generator does NOT have two coils producing 120 volts, it has ONE coil producing 240 volts with a center tap so it will also produce 120 volts. Any attempt to combine the two is guaranteed to produce a massive short circuit and major damage.

It's a fact, the laws of physics say you CAN'T put 2 coils in a generator. You can put in one, or you can put in three, but two is impossible.

This is wrong. There are many generators that have two separate windings and can be connected for either 120 volts or 240 volts. Many Onans provide that option. I own two of them. My Onan CCK 4000W is normally connected to provide only 120V AC power to my RV. It has four wires at the output - one pair for each winding. I strap them in pairs to get 120V at 33.3A (the windings are in parallel). When a hurricane comes along and I need 240VAC for my well pump, I reverse one of the pairs to get 240VAC at 16.6A (the windings are in series and act like a center tapped single winding). I own another Onan (6500W) that I purchased wired for 120VAC and rewired for 240VAC.

I don't know if the Generac has the 120/240 rewiring capability, but it's certainly not impossible. For an Onan, it's easy to tell from the model number. The AC connect cover plate as well as the manual will have a wiring diagram for both 120 only and 120/240 configurations.

I'll also comment that in many generators that have the dual winding 120 or 120/240V capability, only one of the windings is monitored during voltage regulation. There is usually a warning in the manual that when you are using the generator to power unbalanced loads (all the load on one winding) you should connect the load to the monitored winding, not the unmonitored one.

I just don't understand why you don't just plug into the 30A outlet on that generator and power up your rig :H
