Ground Fault Circuit Interrupters
Ground Fault Circuit Interrupters, or GFCI’s should be used for all portable or temporary power tools used on the rig. If GFCI breakers are not installed in breaker panels, portable units should be provided that can be placed in line to protect employees from ground shocks when using portable power tools.
Grounding
The rig and its components must be grounded and bonded to ensure a clear path to ground in the event of a short circuit. The ground rods must be installed before starting power generation equipment and not detached until generators are shut down. All buildings and electrical equipment must be bonded to the ground system.
