RV Breaker panel

[Colo_Native]

I am getting ready to start the inverter project and the breaker box in the FW has Murray MH-T breakers what is compatible to put in there? Need a 30 amp single pole.

" its against code and dangerous to back feed the main panel from the inverter"

NEC Article 690 specifically ALLOWS an inverter to backfeed into the service panel (690.10(C)).

" use dedicated NEW circuits for inverter output"

That's exactly what the OP is proposing to do.

If equipment is properly labeled to indicate multiple power sources, this arrangement is acceptable.

That relates to a Solar Grid Tie inverter that shuts down when utility power is not present.

OP is feeding a sub-panel with a transfer switch inverter so no actual back feed.

Take a Breaker with you to Home Depot or Lowes or _____ hardware or Electrical supply.

As others have tried to say and I think you are planing on doing

Main breaker box-(30 amp branch)----Inverter----Sub panel (branches to loads) sub panel may be part of inverter.. or not, since yours is after market I'd guess NOT.

Suggestion: If you have not already purchased the sub panel.... Get one that takes the SAME TYPE OF BREAKER that way you don't need to worry about "This one or that one". That is one thing CW did right on my RV. (They made two mistakes on the install but they got that right).

I was going to suggest take an existing down and match it up.

I found one only online at Home Depot. Thanks

Murray breakers would clearly be compatible; so are at least some Siemens breakers, I believe, and perhaps some others share the same mounting. (Siemens owns Murray). Specifically, you should look for an MP-T series single pole breaker or equivalent. This should not be too hard to find, and certainly not hard to order online. (MH-T breakers are the tandem version of MP-T breakers.)

When I installed a replacement converter with circuit breakers and fuses in the Power Distribution Side of it I was able to find matching circuit breakers from LOWES Electrical section. They have a large selection of different brand circuit breakers... They had the exact brand of the circuit breakers I was matching up with...

use dedicated NEW circuits for inverter output
Or
use a sub panel for the inverter output, move circuits to the sub panel
Or
use a transfer switch between inverter and existing breaker output to feed existing circuit

It is for the 30 amp feed from the rv panel to the inverter then to the sub panel. I need a breaker on both sides of the inverter according to the Magnum instructions
