Answer: 70 to 100 milliamps
Although fatalities have occurred at lesser amperages.
Most circular saws draw between 12 to 15 amps, which equates to 12,000 to 15,000 milliamps . . . more than 100 times the current that can instantly kill.
Most drills draw between 5 and 7 amps (5,000 to 7,000 milliamps) and again, this is far more current than the lethal range.
On a construction site, nearly all electrically powered tools draw a sufficient current to be fatal.
Be sure to inspect all extension cords and cords on tools for damage or excessive wear. Use GFCI protection. Protect electrical cords from laying in water or exposure to wet weather elements.
