Running a standard receptacle on GFCI line
It may not be higher load levels but a problem with GFCI's and motor loads, my state exemption for GFCI's includes refrigerator and freezers. If the refrigerator is the first outlet in your kitchen small appliance branch circuit a GFCI outlet can be added to the next outlet and be legal with NEC2014 code. I am out of town and do not have my code book but there is an exhibit showing the refrigerator as the 1st outlet and the rest as GFCI protected on 1 of the 2 small appliance circuits required. I like the refrigerator on its own circuit but it is code to put it first or last on one of the 2 required 20a circuits,,, if not first expect to loose a lot of food, In my professional opinion.
