What is the minimum size of conductors that may be installed in parallel?

The minimum size of conductors that can be installed in parallel is 1/0 AWG. This standard is set to ensure that when conductors are run in parallel, they can effectively share the load while maintaining safety and efficiency. Conductors need to be sufficiently sized to handle the current without overheating, and using conductors that are too small can lead to an increased risk of failure or fire.

Parallel conductors are often used to achieve the desired current-carrying capacity when a single conductor is not sufficient. It is important to select the right minimum conductor size to ensure even distribution of the electrical load across all parallel conductors, which 1/0 AWG fulfills. This standard helps maintain compatibility with NEC (National Electrical Code) guidelines and safety practices for electrical installations.

While other sizes are available as options, they do not meet the minimum requirement established for safe parallel installations.
