Hi Adam, This response is just to you. Is NYSERDA the inspection agency you are talking about? Cause they have given me issues about using Wago Nuts inside a 3R box, even after I got a statement from Wago saying that it is okay to put it inside a 3R box. But squirting a bit of No-Ox in there seems to make them happy about it. The one time we put one inside a 3R panel board to extend a short wire and forgot to put No-Ox on that one, they gave us a 2 out of 5 on the inspection, even though that was the only thing noted in the entire inspection report! But I would be curious if the point you make above will work with NYSERDA?
