Flexible cords shall be connected to devices and to fittings so that tension will not be transmitted to joints or terminal screws. This shall be accomplished by ___.

• A. Using a special fitting designed for this
• B. Winding the cord with tape
• C. Tying a knot in the cord
• D. Any of these

Answer: (D)

The need is to prevent pulling forces from reaching the device terminals by providing strain relief. The reliable way to do this is to use a fitting or clamp specifically designed to take the load and secure the cord, so the tension is not transmitted to terminal screws. Wrapping with tape or tying a knot near the connection does not provide durable, reliable relief and can lead to loosened screws, damaged insulation, or hidden damage. So, the best approach is a purpose-built strain-relief fitting; improvised methods are not a dependable substitute.
