Metal-clad breakers are commonly operated by _____________.

Metal-clad breakers are commonly operated by _____________.

• A. hand
• B. switch sticks
• C. shotgun sticks
• D. remote control

Answer: (D)

Remote control is used to operate metal-clad breakers because it keeps the operator out of the arc-flash and high-voltage area while the breaker is being opened or closed. These breakers sit inside protected metal enclosures, and the control system—often tied to protective relays—allows tripping and closing from a safe control panel or room, enabling fast, coordinated actions during faults and routine operations. While manual methods like using insulated handles or switch sticks exist for some gear, they require close proximity to energized components and carry greater risk, so remote control is the standard practice in modern metal-clad switchgear.
