30 amp coaches with ECC

The ECC requires NO 120 to operate its controls. The only line for the ECC to the breaker box is for the current sense at the breaker box. Sooo, the 20 amp Breaker labeled ECC goes direct to 1 AC unit and the other labeled AC goes to the other AC. Turn off each breaker 1 at a time to determine which breaker goes to which AC. My bet is the ECC breaker goes to the front AC. Doug

PS. the bottom pic you sent is for the 12 volt DC fuses.

Well I had a chance to try it out while plugged into a 15 amp breaker, and sure enough, the ECC breaker goes to the front AC.

Thanks Doug!

I won't be at a campground to try flipping the breakers for a couple of weeks. In the mean time I could try it while being powered by the generator. Will that give me the same results? I believe while running off the generator, one AC runs off the 30 amp power from the generator along with everything else, and the other runs off its own 20 amp circuit.

On Genset, the ECC is not activated. The rear AC runs off the 20 amp breaker on the genset and the rest of the RV runs off the 30 amp breaker on the Genset. So, I doubt you will get the same result as usually, they have a transfer box for the 20 amp genset to the rear AC. BUT, turn the Genset 20 amp breaker OFF and then you can do the test on Genset.

Im guessing the ECC uses its 20A to run the rear ac unit. Have both running and flip the one labeled ac off.

Here is the breaker box:




This is the label for the 12 volt fuse panel as long as I'm taking pictures:

Talked to Fleetwood
1. They built very few of this type system
2. They suggested to turn OFF the AC breaker. But they did not state where it was if not at the main breaker panel. IF you have 2- 20 amp breakers in your breaker panel, they are for the roof AC units.
3. It is an Intellitec system and Fleetwood calls it the ECC-2.
4. The Intellitec wiring schematic shows 2 separate 20 amp breakers at the main breaker panel. Each goes to just 1 AC, so, if wired to specs you should be able to kill either AC from its appropriate breaker. Doug

There has to be a breaker for each A/C. Could it be that you have 2, 20 amp breakers with one lever? Could you show us a picture of your circuit breaker panel. There is a answer to your problem some place.

My manual has a blurb about 50 amp service too. It also says that there is a bypass valve in the utility compartment so I can fill the fresh water tank from the city water inlet....but it doesn't have that valve. It's an error.

I think that a lot of the stuff in the manual is just generic stuff that applies to more that then Fiesta/Terra models. I have noticed other discrepancies and generalities as well, which lead me to believe this is the case.

Back to the issue. I only have one breaker labelled AC, so unless there is one hidden somewhere or mislabeled, I can't just turn on AC off.

EACH AC has its own dedicated 20 amp breaker. You cannot connect 2 AC units to 1- 20 amp breaker. That said, on 30 amp RV's, it is doubtful that BOTH AC units will be wired at the breaker panel as a 30 amp breaker panel will not have enough breaker slots for the additional AC. Usually, on 30 amp breaker RV's the rear AC is wired to the Genset. then depending on the OEM, that Genset breaker going to the rear AC may go to another transfer box or front/rear switch to change AC options for 120 power. You need to call Fleetwood with your Vin number and have them explain your particular system. Doug
