I have been popping a 30A breaker for my radiator fans, was usings Klixon 7271-8-30. After looking up the Spal part # va33-ap71/LL-65a I have learned each fan has a 22 Amp draw. I am having a tough time finding a comparable 45 or 50A breaker. Any help sourcing one would be greatly appreciated. What size breaker is recommended or most commonly used on big double rad fan setups? Thanks in advance.
