This weeks 2017 Code change is not a change but a clarification to a Code section. It is based on 201.8 GFCI protection and how we measure the distances from a receptacle.
“For the purposes of this section, when determining distance from receptacles the distance shall be measured as the shortest path the cord of an appliance connected to the receptacle would follow without piercing a floor, wall, ceiling, or fixed barrier, or passing through a door, doorway, or window.”
So from the edged of the sink to the receptacle for the disposal you pass through a doorway (most of the time). Some will say that because the dishwasher is on GFCI it also includes the disposal, that is not the case the dishwasher placement on a GFCI protected circuit was based on a request from the manufacturers to place the dishwasher on a GFCI protected circuit. Maybe some day it will be required to be on a GFCI circuit but not in the 2017 Code.
My last post for the lug guards was also a 2017 NEC Code change.
Till next time be safe work safe
