I have a debate over the effectiveness and order of plugging tools into an extension cord into a GFCI pigtail and into a portable generator. The argument questions the scientific necessity (Safety) and order of plugging the GFCI pigtail into the generator before the extension cord vs plugging the extension cord into a generator and then the pigtail, followed by any tools. The argument centers around a worker having to travel an extra 100' to reset a tripped GFCI at the 'source' while using an extension cord or merely traveling the distance of the tool cord into the pigtail which is plugged into the extension cord at the user (female) end. Does it matter where, in the temporary electrical supply chain, the GFCI is plugged in as long as it is between the source and the tool? Is the worker still protected?
