How many conductors can a clamp accommodate according to NEC guidelines?

The National Electrical Code (NEC) establishes specific guidelines for the installation and use of electrical equipment to ensure safety and functionality. When it comes to clamps, particularly those used for securing conductors, the NEC allows for one conductor to be accommodated in a single clamp. This regulation is in place to prevent potential issues such as overheating, overloading, or difficulty in creating reliable electrical connections that could result from multiple conductors being inserted into a single clamp. By limiting clamps to one conductor, the NEC aims to promote safe practices and effective electrical system performance, ensuring that all components operate within their rated capacities and do not introduce hazards into the electrical system.
