Our house currently has a transfer switch to our main panel. Our barn has a subpanel that houses our electric fence and more importantly, well pump. As of right now, the transfer switch does not provide power to the barn. The barn has a two pole breaker in our main.
I attached pictures of our panel labels (rooms are correct but red outlining for generator is not--we had some work done recently and the electrician didn't move some of the transfer switch wires) and the actual wiring. The barn breakers used to be where the current surge protect is located. The previous owner did have it hooked into the transfer switch.
My question, is there a simple solution to hook up the barn to the transfer switch? We don't need or want the oven, dryer, or garage on the generator (currently hooked into the transfer switch). They just won't be needed during our power outages. Moreover, we don't need the heat pump as we will just use the furnace.
Additional info incorrectly posted as an "Answer":
There is a main switch on the bottom not pictured. It is an older panel in an old house. We have a 10 circuit transfer switch. However, we have some of the wiring going to breakers we don't need on the generator.
Ignore the blue and yellow dots in the wiring picture (they were for my reference).
