Myth #106

Myth #106 revolves around the belief that any screw can be used to secure wiring devices (like switches, outlets, or light fixtures) into outlet boxes, according to Section 406.5 of the National Electrical Code (NEC). However, this isn't entirely accurate. NEC Section 406.5 outlines specific requirements for the types of screws that should be used to secure wiring devices. It states that only screws provided by the manufacturer, or those specifically listed for the purpose, should be used. This is important because the screws provided by manufacturers are often designed with specific features to ensure proper installation, such as the right length, thread pitch, and head design to securely fasten the device without damaging the wiring or the outlet box. Using improper screws can lead to several issues, including poor electrical connections, damage to the device or wiring, and even safety hazards such as short circuits or electrical fires. Therefore, it's crucial to adhere to NEC guidelines and use only the screws recommended by the manufacturer for securing wiring devices into outlet boxes.
