Title5D30.u1 - GFI Guy
Objective

Demonstrate the dangers of 120-volt AC and show the safety features of GFI outlet circuitry.​

StatusAvailable
Assembly Instructions

Instructions
A little cardboard cut-out person (generic, Bart, or Lisa) is carefully attached to a line cord that is later either plugged into the regular AC outlet or the GFI outlet and any two leads may be chosen (hot/ACneutral, hot/ground, or ACneutral/ground). The electric clips pass the current through a ~ 100-ohm 'heart', which begins to smoke and then bursts into flames and arcs. If the GFI outlet detects any current through the ground lead it pops open the circuit, thus saving the little person. So, clipping the little person to AC hot and ground on the GFI outlet will not be lethal.​
