Do you remember the post from November 2012? Do you know what a GFCI does for YOU?
A ground fault circuit interrupter, or GFCI, is an inexpensive life-saver. GFCIs detect any difference in current between the two circuit wires (the black wires and white wires). This difference in current could happen when electrical equipment is not working correctly, causing a ground fault. If a ground fault is detected in a GFCI-protected circuit, the GFCI switches off the current in the circuit, protecting you from a dangerous shock. GFCIs are designed to protect workers from electrocution. GFCIs are able to detect the current through a person who is beginning to be shocked. If this occurs, the GFCI switches off the current in the circuit. GFCIs are very different from circuit breakers because they detect short circuits rather than overloads.
Some code to pay special attention to:
- GFCIs MUST BE TESTED DAILY.
- All GFCIs must be plugged into a grounded circuit. This means your generator must be grounded.
- To stay compliant with OSHA 1926.404 (b), (1), (i) Stratus Staff MUST have GFCIs on all extension cords during use.
- Grounding is required for the GFCI Test Button to work correctly.
- GFCIs are required for all temporary (<90 days) installations during construction, maintenance, repair, or demolition (NEC 590.6).
- Applies to power from the grid and generated power sources.
- NOTE: Generators manufactured before January 1, 2011 were not required to provide GFCI protection.
How does this impact you? Make sure all of you carry a GFCI pigtail (not considered daisy chaining) or make sure your power source has a working GFCI in line. Test that GFCI with the buttons, and if it fails, stop work and remedy the broken GCFI.
