I have just moved into a new construction home. The home came with a sub-zero refrigerator. I found that the fridge is not wired on a dedicated circuit, but is on one shared with outlets above the counter. Sub Zero requires a dedicated circuit per their documentation and FAQ:
Answer: All Sub-Zero, Wolf, and Cove appliances require a dedicated electrical circuit.
It seems that in general NEC codes does NOT require a dedicated circuit as discussed in this post.
This seems consistent with other research, except for when people are talking about Sub Zero e.g., from 2002 "Also, no sep. circuit is needed unless the fridge is a sub zero, then make it a 20a circ" and more recently here here.
I read that some inspectors will force compliance with manufacturer requirements (e.g., if Sub Zero says you need dedicated, then it has to be dedicated to pass), but it's not a given. Is there anything actually in the NEC code that I can use to force them to actually put the fridge on a dedicated circuit? e.g. something about the power draw or other specs of the sub zero fridge override the normal conditions that wouldn't require a dedicated circuit?
I would like to better understand what the diff is between a sub zero and other refrigerators that actually make this more important than regular fridges. What is the real risk - can I damage my fancy fridge if I plug in the wrong type of device to one of the wall outlets?
Also, not sure what is going on with the wiring - the outlets are GFCI and testing trips the other outlets, but not the fridge outlet - does this play into the logic of the way they connected the fridge?
Additional Info: I think there actually is a dedicated outlet behind the fridge based on what I saw during construction. Right now, the fridge is plugged into an outlet in the cabinet above the fridge instead of the one I would have expected halfway up the wall behind the fridge.
They told me there was not enough space back between wall and fridge to use that outlet (seems unlikely, the cabinet maker knew the exact appliance going in, so unlikely they didn't make it big enough).
Since it's a pain to remove and move around the built in fridge I wanted to get more information in case it turns out there really isn't enough space and they need to spend money to make it right.
If needed - the fridge model is: 36UFDID/S
