Rosie bypass circuit breakers

[qrper]

Ever have one of those 'ha ha' moments? I sure did the other night. My wife was caught up watching the real housewives of someplace or another when it hit me.

From Rosie to my essential load panel, there are no breakers! I was thinking the bypass breaker, at 63A would do the job. Then the more I thought about it, if there is a fault in my load panel and the Rosie breaker trips, doesn't it pull the other side of the bypass breaker down (up?) too?

Or does the breaker simply open and nothing moves?

Do I need to somehow shoehorn a breaker between Rosie and my load panel?

Q,

I have a similar setup. My Rosie outputs to a DP breaker in my main before it feeds the other circuits. I would think that in my case the DP on my load panel should trip and disconnect the Main panel from Rosie regardless of the condition of the Rosie e-panel change over breaker. Is your system setup like that.

My plan is an MNEAC60 for AC in and out on my Rosie. Regardless of if there's a breaker downstream at a panel.

If you trip the 60A output breaker it will not turn ON the bypass breaker. No secondary protection would be needed unless you ae running less than 60A wire from Rosie to the subpanel. For example, if you ran #10 from Rosie to a subpanel then yes you need a 30A breaker as the wire is too small for the 60

Thanks! That's exactly what I wanted to know. Was a bit concerned about popping the inverter's output breaker and then having the ac grid out switch on.
