• At about 100 milliamperes (less than half that
used by a 25-watt lamp) ventricular fibrillation
ocuurs, the muscle fibers lose control and the
heart is no longer able to pump blood.
• When a tool is operating normally, electricity
passes through one wire the tool and back out
the second wire. Little or no current should
travel down the ground wire.
• If a tool’s insulation becomes defective, some
of the electrical current will pass through the
tool’s case to the ground wire and back to the
ground. The person holding the tool will not be
injured. If enough leakage current flows, the
line fuse will open. The only problem is that
this depends on a good ground path all the
way back to the ground itself.
• If the ground wire doesn’t make a perfect
contact all the way back to the ground, the
leakage current will flow through the operator
to the ground. The amount of shock the person
receives will depend on how defective the
tool’s insulation is and how well grounded
the main is.
