The primary safety goal of limited-energy cabling is to minimize which hazards?

• A. Heat generation
• B. Electrical noise
• C. Voltage drop
• D. Shock and fire hazards

Answer: (D)

Limited-energy cabling is designed to keep the amount of energy available in the circuit very small. With less energy available, the potential for harm to people and for starting a fire is greatly reduced. The main safety concern in electrical work is electric shock and ignition risk, so the primary goal is to minimize those hazards. Even if a fault occurs, the limited energy means the current and heat that could be released are small, making shocks and fires much less likely. Heat generation, electrical noise, and voltage drop matter for performance and reliability, but they aren’t the primary safety focus.
