50 AMP Service Line 1, Line 2

[96kpmjmm]

Is it possible to move my Kitchen Air Conditioner/Heat pump from Line 1 to Line 2 . Line 1 has a disproportionate share of the large AMP usage, Kitchen, Living room AC,s, battery charger, Microwave, one of the heating elements, all of the outlets and a bunch of others items.

Just a matter of trading places/swapping breakers in your breaker panel from leg one to leg two. A well balanced panel is always a good idea.
Calculate your worst case amperage draw scenario and try to equalize each side appropriately.

Yes but the other side is most likely all the stuff on the inverter so if the ac tries to turn on when you’re on inverter the system won’t like it. But rearranging the breakers is is no big deal.

I came to the same conclusion and will try to balance my L1 and L2 in a few weeks when we get to our Florida spot, but you have to be careful not to overload either line or any of the breakers.

The way I will approach it is this:

1. Make a list of what each breaker in the panel feeds
2. Make a list of the amp draw of each item fed by each breaker in the panel
3. Take a look at the changes I want to make and see how that affects the current draw on each affected breaker
4. If the amp draw on each breaker in the new configuration is not exceeded, then go ahead and switch the wires.

CAUTION: IF YOU DON'T DO THIS CORRECTLY, YOU COULD OVERLOAD WIRES OR BREAKERS AND CAUSE A FIRE.

Just my opinion.

Good point. I assumed his new coach would have a sub panel for the inverter fed circuits. Could be wrong though.
I would definitely look at the wiring schematic before attempting to balance any electrical loads in the main breaker panel.
Proceed cautiously if in doubt.

I didn't even think Line 1 was all the inverter stuff. So my problem is when we get to a campsite and if its hot out and dinner time ( microwave ) and battery charger is going am pushing it. Here is how my lines are set up


Line 1 Living Room A/C
Line 1 Kitchen A/C
Line 1 Microwave
Line 1 Front and Rear Floor Heat
Line 1 Block Heater
Line 1 Battery Charger
Line 1 Kitchen Under Cabinet outlets
Line 1 Hutch Power Strip
Line 1 Master Bath GFCIs
Line 1 Small Bathroom Cabinet
Line 1 Zone 1 Floor Heat ( Front, Rear )
Line 1 Outlets Next to Passenger Chair
Line 1 Outlet Next to Recliners
Line 1 Outlet next to bed
Line 1 Electric #2 Element for Oasis

Line 2 Bedroom AC
Line 2 Stovetop
Line 2 Mid floor heat
Line 2 Washer/Dryer
Line 2 Kitchen counter top outlet ( aftermarket not on Inverter )
Line 2 Electric #1 Element for Oasis

The inverter is on one line but it doesn't carry all line one thru it. Its a 30 amp branch circuit to a 50 amp leg.

Makes sense especially after seeing the list above.

Just my opinion.

How would that happen ?

Each bus bar, that the breakers connect to, are protected by the 50 amp breaker.

Keep in mind that there may be an energy management system of some type that automatically sheds loads. On our Canyon Star the sense lines were connected to the A/C breakers so I had to be careful when rearranging them. Unfortunately Newmar does not have really good wiring diagrams (at least they didn't for our coach) so take the time to document where everything is so you can put it back if necessary.

My opinion is moving the kitchen A/C to line 2 is a low risk option. If you could move it and not exchange with anything that would be best, otherwise you'll have to decide what to put on line 1. My vote would be the washer/dryer or stovetop.

Also, it looks to me like in the list above Line 1 includes all the inverter loads, is that correct?

One potential help could be to adjust your battery charger input current. On my 15 Ventana I've set the batter charger input current limit to 5 Amps. Yes it will not charge as fast but once we stop I'm going to be there for at least 15 or more hours which so far has been more than enough time to get the batteries topped off. Note that the 5 Amp limit is on Input current, I don't recall the charger max output when the input is yet to 5 Amps although I believe I've seen around 40 Amps of charge current reported bu the PCS control panel.

Yes Line 1 has the inverter loads, If I have to exchange it would be washer/dryer. I am not a electrician so ether Newmar or the RV tech i have used will do this

Silverleaf will need to be reconfigured after you move the circuits so load shedding will work properly.

Good idea, I didn't think of that. Am going to look at that tomorrow. Thank you
