Our first motorhome ('99 Southwind) was wired for 30 amps, so we purchased and used a Progressive Industries 30A EMS plug-in unit. Now we own a 50-amp coach ('04 Revolution) and we purchased a Progressive 50A plug-in unit. We still have the 30A EMS from the Southwind. We also have a 30-amp male/50-amp female cable adapter. My question: if we are at a location where only 30-amp service is available, which way should we connect? A. 30-amp CG connection--> 30-amp EMS unit--> 30-to-50 adapter--> cable to coach -OR- B. 30-amp CG connection--> 30-to-50 adapter--> 50-amp EMS unit--> cable to coach Thanks! --Tim C.

I was wondering if while hooked up to 50 Amp service and my 2011 Fleetwood Discovery 40G reads 30 Amps, if it will hurt anything or just limit what all I can run in the coach? I checked the 50 amp plug at the box which is a standard 4 post (X,Y,W, &G) plug, but it looks like the electrician wired it with 120 coming off of either L1 or L2 but not both because I see zero (0) volts across X and Y with my voltmeter. I see 120 Volts between X and W and Y and W and X and G and Y and G and zero (0) between W and G. Since it looks like the 120 is coming from the same side, which means the phases will not be balanced, is that a fire hazard on the coach side or the park's side? Also I would be curious as to why someone would wire a 50 Amp service in this manner? Does it save money somehow? I checked the feeds coming into the bottom of the power box and there are 4 wires coming in and 4 going out, so they did not jump the poles in RV service box, which must mean they did it at the main circuit box. Thanks!

Hi - I'm a newbie. We've had our 2005 Winnebago Journey 39ft since the Summer and I'm struggling to get 50 amp power inside the motorhome. We've plugged into many 50 amp outlets at different campsites but all I can see on the panel is 30 amp. Part of the problem is that I'm a real novice with electrics so I'm not really sure where to look...the inverter? the panel etc... Perhaps there's someone kind enough to point me in the right direction? By the way, we're on a winter trip from our home near Mt Rainer, WA to Vegas, Anneheim, San Diego, Sonoma and in January back home - we're enjoying RVing a lot. Many thanks! Chris

My MH is a 30 amp unit. I have recently acquired a 5.5 kw onan generator with two 30 amp breakers. Only one 30 is currently powering my MH. I have the other 30 amp line capped off. Could I run the capped off one to my rear ac? Then I could run my front ac on the coach circuit and the rear ac on the other 30 amp line? Thanks, I am new to RV. My MH is a 1989 Safari.
