Need a small breaker panel to finish Inverter Replacement

[bigbillsd]

I am looking for a small breaker panel that will take a 30amp main from my inverter output terminals and has room for at least 2 @ 20AMP breakers to protect the coach outlets. It needs to be surface mount and "pretty small" to fit into the inverter compartment area. The old inverter had two built in 20 amp circuit breakers for the output lines, the new higher capacity inverter does not have that feature so I need to protect those 120 volt circuits very close to those output terminals.

Here is a pic from the manual of the setup I circled the part in Yellow that is need to find a source to purchase it from.

You don't need a main. Your main between your power cord and inverter protects on shore power. Your inverter shut down circuits protect on inverter power. Is your inverter even capable of enough power to trip a 30A breaker?
If you really want one then get a 2 space breaker panel like the many that have been shown in this thread, install a "main" 30 in one slot and a tandem 20 in the other. Then wire the output of the main to the input lug of the other buss bar holding the tandem.

I bought this same one for mine.

If there is no main, what would protect the inverter from both circuits pulling 20amps and overheating the 30amp circuit to the inverter? I understand that scenario probably shouldn't happen, But..

The 30 amp should trip before it overheats.

The big-box home improvement stores have service disconnect boxes and small load centers. They sometimes clearance them because sales are low. I bought my last 75 amp load center for around $25, IIRC.

An alternative is to buy surface mount breakers and wire up the distribution from those. You can make it all look good by mounting the breakers on a piece of aluminum plate. Here's a good place to shop for circuit protection: Waytek Wire. Mounting three surface mount breakers will use about 1/8 -> 1/4 the space of a steel box. If you'll pay the price, the Cooper-Bussmann manual breakers are the way to go, they even sell a sealed Marine type (not necessary, IMO).

The 30A breaker in the main RV panel that feeds the inverter does precisely this. That breaker is needed; a main breaker for the subpanel is superfluous. (If it's running on inverter power, and not pass through, then presumably the inverter's protection circuits would limit current by shutting down.) If one's still worried, use 8 gauge wire rather than 10 gauge wire between the inverter and the subpanel and it won't be overloaded even if 40A is flowing.

May not work for your needs, but my setup is similar and I used twenty amp inline fuses to protect my outlets. Not as convenient as circuit breakers but fit in a very small space. You can purchase 120VAC fuses at appliance repair stores.

Hi Bill,

I found a very small "Homeline" panel, two space four circuit. Ordered it from the home depot website.
