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

The recommended size of tie wire for conductors that are #4 and smaller is indeed #6. This recommendation is based on the need to maintain adequate strength and flexibility while ensuring safe and secure connections. Tie wire must be able to withstand the mechanical stresses of installation and any potential environmental factors without breaking or losing its grip on the conductors.

Using a #6 tie wire for #4 conductors provides a balance between durability and manageability, ensuring that the tie wire can adequately support the weight and tension of the smaller conductors. It’s also important for the tie wire to be compatible in size with the conductors to prevent damage and maintain function over time.

Choosing other sizes, like #4, #2, or #10, may not provide the same level of effectiveness for the specific requirements of securing #4 and smaller conductors, as they could either be too heavy or too light for optimal performance. This highlights the importance of following standard recommendations in electrical practices to ensure safety and functionality in installations.
