What I have noticed, over the last several years anyway, is how difficult it is sometimes to decipher range manufactures listed installation instructions and electrical requirements.
Often they list a minimum circuit ampacity as well as a minimum conductor size that doesn’t seem to correspond directly to the nameplate rating of the appliance.
I can remember a couple of years ago with one dual-fuel range, the installation instructions said to install a 30A 4-wire receptacle in the location specified on the template, but when I read the actual electrical requirements in the instructions, they stated to use a #8 minimum conductor size for the branch circuit.
Because of this, I always try and get copies of the manufactures installation instructions whenever I get the appliance schedule for a job.
