How do you determine the correct size of the cable for a support system?

Determining the correct size of the cable for a support system is primarily based on considering the branch size and the potential load it must carry. This approach ensures that the cable is adequately sized to handle the weight and stress that will be exerted on it. Larger branches or heavier loads necessitate thicker cables to provide sufficient strength and minimize the risk of failure.

Using this method is crucial for ensuring the stability and integrity of the support system, especially in dynamic environments where factors like wind, ice, and growth can affect the load on the branches. Such considerations prevent unforeseen issues that could arise from under-specified cables, which might not provide adequate support.

The other options, such as selecting cables based on color, factory standards, or only the length of the strands, do not take into account the specific requirements of the tree or the load it needs to support, and therefore, would not result in a suitable or safe choice for tree support applications.
