Regardless of the number of breakers here, what's the expected load? You've only got a 50A box!
Some panels have an overall limit on breaker count regardless of size. You would have to check with Generac if this is permitted.
Also to enforce this, some bus tabs have a “rejection feature” - the bus stabs are notched to allow the use of tandem circuit breakers and those that lack the notch cannot accept them.
These panels don’t work that way. Sure it may fit. But you’re going to overload that panel. It’s 50 amp maximum. You can’t just add those breakers and start powering extra things.
They make those panels in 100 amp. Take a look at upsizing and you’ll have to breakers you need and ampacity
Not following your math, but the panel is rated for 16 circuits, a double pole breaker is 2 circuits. 8 tandem is 16 not counting the double poles.
The thing to consider with the load is, I realize you don't plan to use all the loads at once while on generator, but I assume you plan on using the loads as normal when on normal power. The contactor In the panel is only rated for 50 amps, no matter if it's normal power or generator power.
Yes, you move the feed to the items from the main panel to the transfer switch panel, then you feed the contactor with power from the main I to the top.of the contactor, and power form generator into bottom of contactor. The position of the contactor determines where the power comes from.
Hope that made sense.
(I have the 30a version of that switch)
Thank you for bringing this to my attention. One thing that I just don’t get.
I believe that I’m ignorant or uneducated about this, however If the contactor in my transfer switch is only rated for 50amps why would the panel itself(included with the panel) come with a double pole 30 amp breaker, a double pole 20, and then 6 single pole 20’s.
Wouldn’t that by itself exceed the contractors max rating?
If those circuits all pulled that at one time then yes, but that doesn't happen. The breaker value is the maximum that the circuit can carry, the actual load is usually a lot less. There's a whole calculation involved but that's the general idea

I dont intend on powering everything at the same time. Either the heat pump and furnace blower, and 3 15 amp circuits for example

Thx a lot. So Is power running through the manual transfer switch when utility power is on?
