It is a requirement on ALL construction sites for all 120 volt, single-phase, 15 and 20 amp receptacles which are not part of the permanent wiring of the building and which are in use by employees to have ground fault circuit interrupters for personal protection. These simple devices are to be used without exception and shall never be disconnected or defeated for any reason. The electricians control the electrical feed on a job and we don’t want anyone to get shocked much less electrocuted. The alternative is an assured equipment grounding conductor program which requires daily inspections, tests and tons of paperwork!

This is one of the best devices ever made with regard to life safety.
