The issues you had, had nothing to do with the Super Neutral, unless you had bad splices or bad cable.I have a project with about 12 modular furniture floor drops for office cubicles. The prints call for 2#12 1#10N w/ #12G. I would like to install 2#12N. I believe it would be better for the computers. Is there a code that will support this. I installed "super neutral" for similar project about 10 years ago and the computers had issues and had to change to separate neutral.
