I'm building out a Kal/EBrew E-HERMS panel (posts on the build-out coming soon).
Question on wiring.
If I have a 30a breaker in my house supplying 220 to my brew panel. Is there a need to run anything bigger than 10ga in the panel? In the wiring diagram I have my 10/4 coming into a contactor (for key switch) and then to a 25a breaker before sizing down to 10ga for the remainder of wiring.
However, I've seen pictures of others that use 6ga out of the contactor BUT go to a DIN block and downsize to 10ga before going to the breaker. I understand that 10ga is rated for 24a, so my house breaker might not trip on a brew panel "overload". However, since the 10ga still goes through the 25/15a breakers...would I be ok either way? Is there even a need for 6ga?
See picture below of wiring diagram, with my drawn-in block with 6ga entering/10ga leaving.
Thoughts?
