Arc Flash: An electrical spark and bright electrical discharge that occurs through the air when large amounts of electricity is present in a gap between conductors

Bonding: Electrical parts that join together to complete a conductive path

Circuit: A complete path of electrical current

Circuit breaker: An electrical device that automatically cuts off electrical current in a circuit when an overload happens

De-energize: The process of the switching off and depleting stored energy sources to equipment and circuits

Energized: Live electrical equipment with available voltage that can produce a current and thus compromising a person

Ground: A direct electrical pathway to the earth

Ground Fault: An electrical current that is lost from the circuit and is instead directed to the ground

Lock-out: A physical lock applied to electrical equipment and electrical circuits once they’re turned off and de-energized

Qualified person: A person who has received the required training on electrical hazards and on the operation and the construction of the equipment for the job

Overload: An overflow of electrical current in a circuit

Personal Protective Equipment (PPE) Devices: Worn by workers for face, eye, head, hand, foot, respiratory, arm, leg, body, and fall protection

Resistance: The material’s ability to cease or decrease electrical current
