Overview

Industries are increasingly adopting the practice of using reconditioned equipment as a cost-effective and environmentally sustainable approach. One specific area where this practice is gaining traction is in switching devices. The types of switches permitted for reconditioning are outlined in Section 404.16 of NEC 2023. According to this section, lighting switches, snap switches, dimmer switches, molded-case switches, and electronic lighting control devices are not permitted for reconditioning due to cost and safety considerations. This update aims to provide clear guidelines regarding the appropriate utilization of reconditioned switching devices.

Applying the 2023 Code

Various types of switches and switching devices are integral components of electrical systems, each designed for specific functions due to their distinct characteristics. Snap switches, for instance, are characterized by their ability to be quickly actuated by a small mechanical force. Knife switches provide a straightforward on/off function with a manual lever. Molded-case switches offer reliable overcurrent protection. Dimmers enable the adjustment of current to lighting fixtures. Butt-contact switches ensure stable electrical connections. Bolted-contact switches provide robust, secure circuit interruption. Finally, control switches encompass a wide range of functionalities, including electronic timing and occupancy sensing.

All of these switches are indispensable in creating efficient and tailored electrical setups to meet diverse electrical needs of various industries. However, NEC 2020 did not provide clarity on the use of reconditioned switching devices. This caused implementation of non-uniform practices. To avoid further confusion and malpractices, NEC 2023 introduced a new section, 404.16, to explain which of the abovementioned switching devices are permitted for use as reconditioned equipment.

Lighting switches, snap switches, dimmer switches, molded-case switches, and electronic lighting control devices are not designed for reconditioning. When these devices malfunction, it is usually more cost-effective to replace them entirely rather than trying to recondition them. Moreover, attempting to refurbish switching devices that were not intended for such processes can result in improper functioning or, worse, pose safety hazards. Therefore, per the 2023 edition of NEC, these switching devices are not permitted for reconditioned use.
