AC Panels

Has anyone replaced the 120VAC distribution panels inside your CC? I must do that because my Sub AC panel no longer has enough breaker spaces. I'm having trouble finding not only a repair place who knows how to do this in a MH, but a source for the new panels, as well. Help.

JC,

I am assuming you would want to do this per the NEC (National Electrical Code)? If not your insurance may be null and void in the case of a fire. If you could find a 100 amp panel it would be about twice the size of the 50 amp you have now. Is there room for that? Also you would need to upgrade your cord reel to 100 amps as well as the transfer switch and surge protector (haven't seen a 100 amp surge protector but there may be some). Then you would have to upgrade the cable from the cord reel all the way through the surge protector, transfer switch and on into the main panel inside the coach. I've heard there are very high end coaches with 100 amp panels but I haven't seen any myself. Never seen a 100 amp hookup either.

Just some thoughts

Double Breakers are available for most manufactures. This won't increase your load capacity, but will allow for more current protected circuits.

What he said...

Older cc here and all breakers are standard size about 3/4 inch wide.

They are standard common style.

They sell doubles that have 2 in same package.

If already small leave as is and add a sub panel someplace.

Barney, you have me stumped. Why the 100A stuff?The sub panel can't receive any AC from the outside; all must go through the Magnum MSH 3012. That inverter technically has a max output of 63A; but the output is really limited to 50A because that's the breaker size in the sub. There's still the 50A per leg for the Main panel; but it's the same. The way I understand, my OCPD for all 120VAC devices fed by the sub is the inverter itself (plus the breaker I mentioned). If you know of an NEC section aim should read, please send.

Others: Even if I put 2 13mm breakers (double) in the std 26mm space, I'll still be short. Plus, one I'm moving down is the front air; and I feel better with it on a std 26mm.

If I knew of a professional nearby who spoke MH electricity, I'd hire him. Anyone know of an electrical guru near Dallas?

JC

We have quad breakers that are 50 amp 240 in the center and 30 amp 240 on the outside in the same size as a standard double pole breaker.

20 amp doubles in single phase are very common so the only issue is being careful to keep loads balanced.

So remove one ac breaker and get 3 double of same size.

One for each ac and one spare.

So maybe a 15 amp for third...

By replacing both ac breakers the loads for the ac units remain on their original positions.

Add circuits for maybe heaters or other high current items that would be used only while on shore or genny power.

Heaters would not be used same time as ac so less risk of overloading the connection point.

this is a good thread i am following... i have explored a little on it in the past few days but yet come up with a solution.

my main panel has two 50a ac breakers/inputs and a 30a breaker for a/c and other breakers (as on a subpanel although the same board). on magnum ms2812, the terminal options are - si/so at 30a, or si/so at 60a. granted, i'd prefer latter for the maximum output.

i am still unsure how to route the wire (6 gauge romex) between main panel and the inverter for 50a and where a separate subpanel could be put at with 3 or 4 (15a) outlets (front a/c will be on one of those)...
