Electrical Question

[Moxxi]

Ok. I finally brought the MH home this evening. I thought that I understood how to hook up the electrical system.

I guess I was wrong.

I have a 2008 Itasca Suncruiser 38T. I am in an RV Park. I plugged in the 4-prong plug.

What do I do now to -
1.) tell my MH that I am hooked up to 50 amp;
2.) turn the AC on?

Did you look to see that the 50 A breaker in the box with the plug is on? If not turn it on.

Was the electrical demonstrated by someone to you to work off the same 50 Amp shore cable before you "broght the MH home" ? If not then lots of things that could be wrong.

If so then it's pretty much the above or a pedestal problem.

Moxxi, it should know automatically via the transfer switch downstairs. It should click quite audibly, and you should see that you're on 50A power at your electric panel readout inside.

Check breakers for the house, your main may be tripped. Also, your transfer switch may be malfunctioning. Again, you should hear a loud click downstairs when it transfers from 12V DC to 50A shore power.

There is likely a circuit breaker on the CG pedustal that is turned off. Most folks turn it off when plugging/unplugging.

Posts #2 and #4 are the most likely scenario. The simplest culprit hopefully.

There is no 12v DC at the transfer switch. Transfer switch transfers AC power from the generator or power cord to the coach.

Sorry, what I meant is, while not hooked up to shore power you're most likely running on the inverter (12V DC). That's what I meant you're switching over from......(DC wise). You are quite correct, DC to 50A does not happen within the transfer switch itself.


Sorry 'bout that.
I should have worded that differently originally.

Sorry, still misleading. Inverter has its own transfer switch built into it. The main transfer switch transfers AC power from the generator or shore power. If the inverter does not find AC power then it starts making AC power from the DC batteries. This transfer is electronic and can not be heard.

gcamper you're right. You're saying correctly what I attempted to, and can't seem to clearly. I really am smarter than that actually. [emoji1]
I should have stopped at "click in the transfer switch" and left it at that, (at least mine does).

Anyway, apologies to the OP if I caused confusion, thanks gcamper for the help. Guess I'm a little mentally tired tonight.

LOL, it happens to all of at time.

Y’all were right.
I flipped the 50 amp switch, & the RV recognized that the 50 amp plug was inserted.

I didn’t flip the 20 & 30 amp switched. Leave them turned off, right?

[Electra 225]

Don't know if I dare continue, [emoji1] but I'd say yes leave 'em off. The 20 and 30 most likely have their own receptacle dedicated to that repective breaker. You're not using the 20 and 30, the 50 is all you require.

As for the 20 and 30 amp breakers in the park box... You can leave 'em on or off so long as nothing is plugged in. I often do a "Blind" switch so I turn 'em all on and off. always turn off when leaving.
