So i was working on wiring up my Honda EV6010 yesterday and it dawned on me that its a 50amp unit [no 30/20amp split like the later ones] but the
coach is set up for 30amps.....what would you do? And if you were going to change something what would be the best course of action to do it.

I may be thinking about this to hard and it really might not matter but im not taking a chance when there is such vast knowledge and expertise out
there to bounce this off of.....

Voltage at batter does no mean much.
Lot of the connectors are corroded.
You need. Real experience to know these things.
That is the difference between a degreed engineer and a technician with
experience.
I put aside my degree and rely on my technical experience since my teens.

Do you mean that it does not have the two breakers for the output?
One of them 30 amp and the other 20 amp?

Just protect everything after the generator with an appropriate sized breaker. The line side wire to a 30 just needs to be rated for the disconnect
before that (ie from the generator to the breaker should be rated for the 50 amps if that is the breaker size on the generator) anything after the 30
amp main breaker needs to be sized for it. Just be sure that the wires connected to any breaker are rated for the amp rating of the breaker.

Where this gets dicey in my opinion is someone makes up a 20 amp circuit and wires it with 12ga thwn and someone else ties into the circuit and uses
14ga wire which is only rated for 15 amps. Now the 14ga wire can be over loaded because it is protected by a 20 amp breaker.

I hope this makes at least a little sense. Best to be safe with the electric systems. No one likes a hot skin condition or under sized circuit on a
motorhome.

Yes.... according to the great folks at PPP this unit is a direct 50amp so one breaker and not the 30 amp/20amp breaker setup like the later
units....

So if i was to just wire it up as is......

I have the stock 50amp breaker coming out of the generator...the plug setup is the standard 30amp three prong that gets connected to a normal 30amp
shore power cord that is wired to a 30amp breaker in the breaker panel etc....

Jim i've been a mechanic now for 40 years with a back ground in racing and fabrication....i am not an electrician nor do i play with 120/240v AC stuff
very often....the stuff i currrently play with is 600 to 900v and over 350amps DC.....hence my question here about a generator that is going to output
120v - 50amps AC when everything is wired for 30amps AC.....common sense says everything should be fine as long as i have a 30amp breaker between the
coach and the generator but i just want options and opinions.

I know that you start at the source, and protect for the worst case
scenario. Human contact with that source. Fusing, circuit breakers, wire
diameters and insulation thickness all factor in. Protect people first,
then facilities.

Protecting everything is important. NOTE a 30 amp RV plug is USUALLY a three prong 120 volts A standard 50 amp plug (and RV plug) is TYPICALLY 4
prong and 240 volts. When you go from 50 amps down to 30 amps you typically drop a leg. There is a plug that does that internally. It is a good idea
to know if that is the case for your generator. From what I know (and that could be incorrect) that generator operates at 120 volts so you should be
fine. If there are four wires that are from the power supply (green white black and red) you have a different animal than I am used to. As long as
you only have the three wires (green ground -- white neutral -- and black) everything I have mentioned should be correct. Best to test everything as
you go. I want you to be safe. The normal configuration on an RV outlet is ground at the top (the round hole green wire) lower left slot is the hot
(the black wire) and the lower right side is the neutral (the white wire). Once again that is looking at the front of the outlet where the cord plugs
in. Obviously the back side would be reversed. The screw for the hot wire (black) should be a gold screw and the neutral wire (white) screw should be
silver and the ground wire screw (green) should be a green screw although that is not always the case with the ground wire.

Yes it is a confirmed 120v at 50amp according to PPP....i will test it of course and they also confirmed the connection required for such. Thank you
for the info and the direct referencing as it will make it easier to validate what the wiring on the coach side is like. [its a Hughes so i have no
schematics other than the GM ones].

AFAIK, GMC-built coaches have 4 kw or 6 kW Onan generators that put out ONLY 120 Volts. However, that 120 Volts is fed to a split 50 Amp socket with the 120 Volts to both "hot" terminals which in a true 240 Volt system WOULD be Red and Black. You can hook up your 4 conductor cable plug either to the 120 Volts of the Onan generator OR to a true split 120-0-120 Volt 50 Amp outlet and all will work just fine. I have a 50 Amp service RV park outlet on the side of my garage as well as a 120 Volt 30 Amp RV outlet so either type of RV can hook up to my commercial power. I also have a manual switch which can select either commercial power OR an 8000 Watt emergency generator at the back of the house.

Rich,

Your confusion and uncertainty is completely understandable. Wire it up the way it is.

The 50amp possible output of the 6010 is in no way related to the 50amp RV service. The two are very different animals.

Just be sure that everything downstream of the 6010 is good for 50amps. That would be #8AWG (not #8SAE and I have no clue what Canadian wire sizes
and types are) and that should be safe enough.

Now, if you have two roof A/C units and might want to run both, come back here are we will have another discussion at great length.

Thanks Matt .... i am probably going to add AC unit #2 this spring but not run both at same time on generator.

I was half thinking of wiring it seperate though so my idea was a seperate junction box or dedicated plug to AC #2 in the cable box. So when at a
campsite i could plug in to 120/15amps for it or somehow split the 50amp plug out of the outlet into 30/20 and plug it in (so 50 amp male that has 2
cables coming out of it split into 30/20 somehow)

If all is properly wired, the 6 kW Onan should be able to run two original A/C units.

Considering your future plans, I would just switch over to 14-50 format at this time. Switch out the panel, cordset and generator receptacle to
14-50R (jumped L1/L2) , wires from generator to 14-50R upgraded. and use the 50A breaker on the generator Otherwise you are leaving generator power on
the table. Some Hondas, I think, were true 125/250 4 wire, but this does not seem the case here with 2 different breaker ratings on the generator. If
it was, you could wire it 1 for 1 to the 14-50R. Two hots, neutral, ground, the latter bonded at generator

I was just actually reviewing this and comparing it to how the Coachmen's were wired with a pony panel from the generator at 50amps then split
30/20....the 30amp leg to the coach and the 20amp leg to A/C....

My option is to do the same or upgrade my current panel to basically the same but all in one box.

My question then becomes do i have to change the shore power cable, the plug for shore power to generator etc? If the answer is yes im going to pony
panel it as my 30amp shore power cable is brand new and its probably easier to just add a small breaker box in the generator compartment at this
point.

What do you guys think? Nothing at the generator is connected yet, although i have run the conduit, its not hard to change at this point really.
