What size tie wire is recommended for conductors that are #4 and smaller?

The recommended size for tie wire when working with conductors that are #4 and smaller is #6. This size is appropriate as it provides the necessary strength and flexibility to secure the conductors without causing damage or excessive strain.

Using the right gauge of tie wire is crucial in ensuring electrical safety and reliability. A #6 tie wire is thick enough to handle potential stresses, yet not excessively heavy, which maintains the overall integrity of the conductor assembly. It helps in avoiding issues such as sagging of the conductors, which could compromise the safety and functionality of the installation.

The other wire sizes are either too thick or too thin for optimal performance and safety in this context. Therefore, #6 tie wire is the suitable choice for securing #4 and smaller conductors effectively.
