GFCI protection

A GFCI trips fast enough to stop a shock from becoming deadly. It only helps if it's there and working.

Key points

• Use GFCI on all temporary power and cords outdoors or in wet areas.
• Press the test button before use. It should trip.
• If it keeps tripping, find out why. Don't bypass it.
• Portable GFCIs work where outlets aren't protected.
• Replace GFCIs that fail the test.

Ask the crew

• Which outlets on site are not GFCI protected?
• Has anything been tripping lately?
