It's off for illustration purposes only, see attached photo...

Whew.. you added an extension too I see... I was gonna mention that there are now too many wires for a standard box

I just had visions of bad things happening while you were sleeping..

Let us know how it works.. I need to do this.. or the whole 50 conversion

After reading about the time, cost and effort of rewiring the coach for 50 amp service, I think this is a great alternative. I took my time during the install and made sure all connections are right and tight, they will not come apart. I spent allot of time tracing wiring, testing continuity, and performing voltage checks before I even started the install. I don't trust the "one size fits all" instructions that came with the Dual Power adapter. Sure I might have to pay more for a 50 amp site, but who cares when you need the heat or A/C?

Do you have a wiring diagram you can share?

Thanks.

Sorry, I have no wiring diagrams. My coach was too old to find one. I doubt you will be able to find one for your '98 National, but you might get lucky.
On my MH the genny powers 2 separate circuits the 30 amp for the coach and a 20 amp for the rear a/c.
I spent a lot of time tracing the electrical wiring from the genset (Onan Emerald 5000) to the junction box. My 30 amp shore power set up has a manual transfer switch so it was not too difficult to trace the separate 20 amp circuit and add the Dual Power adapter to it.

P.S. It is well worth the effort to install the DPA. We already had a few 95+ degree days this season. Sure was nice to be able to run both A/C's at the same time.

If a 30 amp cord, while on genset power has to be plugged into a 30 amp outlet in the storage bay to get full use of the genset, does that mean I have a manual Transfer Switch since I have to plug it in for genset or to the power pole for shore? Until your reply above, I thought I had an automatic transfer switch, but I don't think so now.

Also I have a Duotherm dual AC system that is tied together with one Climate Control Center. And an EMS system to reduce amp usage if it goes over 30. How would these be affected if at all, if I split the rear ac off the main source? When I have the genset running, the EMS does not light up and is bypassed somehow.

Yes, that would be a manual transfer.

I have no EMS in my coach for the 30 amp system. I don't know how this will effect your install. I would recommend making a call to Bill @ Power Solutions.
He should be able to walk you through it.

Hey guys --
I have all the parts needed for this dual power conversion for sale. See the classifieds here in IRV2. I also has extensive set of instructions with it.

RV Dual Power Adapter

It is still for sale. Check it out

If you have any problems I'm in Southern Ohio, about 20 miles from Kings Island just now.. And I built my own so installing is no problem

NOTE: the 20 amp line you tap is not "unused" on a 30 amp coach there is usually both a 30 and a 20 amp breaker on the 5500 watt generator (50 amps) the 20 amp line feeds JUST the rear air conditioner.. This is where they suggest you tap in the PSRV adapter.

In my case (50 amp coach) I had to do it differently.. I understand they now include instrucitons for what I did with the PSRV unit as well.

I just bought the DPA from Tom and Ann and will let you all know how this installs in my rig. I also ordered a 25' 20A extension cord from a supplier in AZ for $40. Thanks all.

FYI- I do have a AC Relay Delay (switch) that operates the rear AC from shore or Genset power, so I will have to insert the DPA in the Genset 20A line to the switch. That should make everything happy, including me.

I may add a 20A outlet for the coach if I can find a way to get it there from the storage bay. I am assuming I won't need AC at the same time I need elec. heat.... So they won't both be used at the same time anyway.

Does Romex (solid wire) meet any vehicle wiring standard?

homerbw · 05-10-2011, 02:59 PM

I installed the power solution last year out of desperation due to hot, hot, hot, Texas summer. I used adapters to plug it into the 50 amp service using a 30 amp extension cord. All the power I could hope for and more.
