i see that in the 18th edition there is now a coding for type fitting , i have been coding any mix and match breakers as code 2 , after contacting lots of manufacturers there guidance is always that they have not type tested any other manufacturers products for there boards, as we know many breakers are manufactured in the same factories and then branded afterwards so they are the exact same product except for branding, when this is the case i code it as a code 3 , would this be the correct logic or shouyld it be code 2 all the way ?
