A GFCI (ground fault circuit interrupter) is designed to prevent accidental shock and electrocution by preventing ground faults. They will continuously match the amount of current going to an electrical device against the amount of current returning from the device along the electrical circuit path.
A grounding fault is needed in areas such as bathrooms and kitchens, or any other potentially wet environment. GFCIs are required anywhere within 5 feet of a water source.
Actions to take to ensure electrical safety:
• Always make sure the tools and cords are in good working condition
• Inspect cords regularly for visible damage
• Use GFCI devices
GFCIs should be inspected and tested on a monthly basis.
