Which type of receptacles provides secure connections with grounding wires?

• A. Standard wall receptacles
• B. Twist lock receptacles
• C. Extension cord connectors
• D. Universal chargers

Answer: (B)

Twist lock receptacles are designed to provide secure connections with grounding wires by utilizing a locking mechanism that ensures a tight fit between the plug and the receptacle. This design not only enhances the safety of the electrical connection by preventing accidental disconnections but also effectively grounds the circuit. Because the twist-lock mechanism secures the plug in place, it reduces the risk of exposure to live electrical components, which is particularly important in environments where equipment might be moved or jostled. In contrast, standard wall receptacles, while they are equipped with grounding capabilities, do not offer the same level of security against disconnection as twist lock receptacles do. Extension cord connectors generally offer basic connection features without the enhanced safety and security of twist-lock systems. Universal chargers, typically designed for compatibility with various devices, do not focus on providing a secure, grounded electrical connection in the same manner that twist lock receptacles are specifically engineered to do.
