Hello,
I have a question regarding table 250.122. The table says(please see attached screenshot) "Rating or Setting of Automatic Overcurrent Device in Circuit Ahead of Equipment, Conduit, etc., Not Exceeding(Amperes)".
So, if I have 16A load with 20A OCPD, which rating should I use to size EGC? Does the word "ahead" mean do I size per 16A rating since the current is going towards the load?
Thank you.
