The 1st and 3rd photos are two 75 amp breakers with a handle connecting them. The 2nd pic is the panel.
I called it 75 amp, because 75A + 75A = 75A
The appraiser told my client it’s 150A.
The letter from the electrician says it’s a double 75A. (Still 75A right?)
The configuration almost kinda looks like a split panel, though I saw no indication of a convenience/lighting section. Just a single double-pole breaker marked as 75A. And that’s it, I suppose
I think you would be correct, Rule is that you call the lowest value. The main breaker is going to pop at 75 amps. Both breakers are 75 amps, and tied together.
I do not believe this is a split panel. If so, there would usually be a visible tie in from the lower breaker (usually bundled in a grouping of 4 2-pole at the top) and the lower section of the panel. Based on the physical configuration, I dont see room for 4 breakers at all. There are the main lugs, with bus bard and the 75 amp unit immediately beluw that area.
Also, the 75 amp breaker is clearly marked as “main disconnect”. You typically will never see it marked as such if there is a possibility of adding breakers at the upper section.
That’s a 150A panel. Those 75’s are wired in parallel like some Siemens and GE panels do with 200’s. They use two 100’s in parallel.
See how the short feeders from the main lugs are run in parallel.
VERY odd setup for sure.
This is one of very old QO series breaker box and that box is 150 amp main rating let me expain a little on this one.
you see non standard arrangement on the handle because this is a paralleded connectioned breaker so it is rated at 75 amp per lug so muti by 2 result is 150 amp.
you should able see the catalog #'s on the side of panel it will tell ya what size it is.
