I just picked up a used commercial oven for my bakery. Now I'm having some trouble figuring out how to hook the thing up. I consider myself pretty handy in general, but I know next to nothing about electricity.
are the specs of the oven, to the best of my knowledge. (These are the specs of the most recent model, but the age of the one I have is unknown.) All the previous owner was able to tell me about is was that it required 3-phase power. The oven currently has a cord, but no plug on the end.
Handily, there is already a 3-phase receptacle installed where the oven will go. Here
is a photo of the receptacle--the relevant numbers stamped on it are 20A.250V.3Φ
Question 1: Can I just purchase a matching Hubbell plug and plug this thing in, or do I need some kind of converter?
Question 2: In matching plugs, there are 3 options available with different "HP ratings." (See page 37 of this pdf.
) How would I figure out which one of these I need?
