I have an rv generator and I am installing it on a trailer for power. The problem I am having is that I don't know what to do with the wires. There are 5 wires coming out of the generator 2 black 2 white and one green. Can anyone tell my how to hook these up to regular wall outlets. I know how to hook up three wires but not five.

thumbless welcome to irv2.

What size are the wires you have coming out of Gen?
If they are heavy gage you should find some info on how to wire on the link provided.

Generators

The two black wires would be split between the two sides of your load center, the two whites would go to the common ground buss of the load center, the green would go to frame cover of load center housing. There maybe a connection for the green wire on back surface of load center. Green is a safty ground in case of poor grounding off white wires a applience ground you some times see on your appliences.
You should also have a heavy number 6 ground wire to frame of coach where you will see other heavy grounds from frame of Gen you will place, converter, transfer ckts etc,etc.
You may have two pairsof ckt brakers from Gen feeding your two pairs of white and black wires.
If you have no clue whats going on find a electrician or a friend who can help, and when your working on power EVERYTHING is disconnected.

While your at it you should add a surge protector to have complete job.

thumbless, welcome to our website and forum. We are glad to have you join us. If your trailer has a 30 amp power cord with three prongs you need to identify the 30 amp circuit off the generator and this is the circuit (1 blk and one wht. wire) you will use to feed the trailer. If you have two roof air conditioners you can use the 20 amp circuit off the generator to feed it; this will be the other blk and wht. wires. The green is equipment ground. It mus be bonded to the fram of the trailer and I would also carry it to the inside of the 120 volt distrbution panel and bond it to the bare wire bus bar. You can use the power cord by installing a 30 amp 120 volt receptacle at the generator. If your trailer is a 50 amp you will need to use a 50 amp 120/240 volt 4 wire receptacle and balance the load so the majority of the trailer is on the 30 amp braker and the lesser (2nd air cond) is on the 20 amp side. If your power cord wont reach or you want to have an automatic connection, you will need to install a transfer switch rated for the size of circuit you use. Good luck and keep us informed as to how it goes.

What you have there seems to be a 6500 kilowatt 52 amp propane fueled generator circa the early 1990's. It should output two 50 amp 110 volt circuits which should not be wired directly to any outlets but go through a circuit panel for distrubution with the appropriate circuit breakers.

The manuals should be available through: http://www.funroads.com/onanstore/osHome.jhtml

When I checked this morning they were closed for maintenance but once they open the info you need should be available there.

If the info there does not seem clear or you are not 100% on what to do please consult a qualified electrician.

These propane fired generators can use a lot of gas so you may want to install larger propane bottles on the trailer if you plan on running the generator for extended periods of time.
