General Electrical Safety

Electrical Shocks

§ Electricity travels in closed circuits, normally through a conductor

§ Shock results when the body becomes part of the electrical circuit

§ Current enters the body at one point and leaves at another

Note: Ground circuits provide a path for stray current to pass directly to the ground, and greatly reduce the amount of current passing through the body of a person in contact with a tool or machine that has an electrical short. Properly installed, the grounding conductor provides protection from electric shock.
