What is the minimum plywood thickness required for mounting the isolator?

The minimum plywood thickness required for mounting electrical components like an isolator is determined by the need for structural integrity and support. A thickness of 1/2 inch is generally recognized as adequate for ensuring a stable and secure mounting surface. This thickness provides enough strength to hold the isolator in place, minimizing vibration and movement, which can adversely affect electrical connections and the overall functionality of the component.

Using thinner plywood, such as 1/4 inch or 3/8 inch, may not offer sufficient structural support, and could lead to issues such as flexing or bending over time, which might compromise the isolator's operation and safety. In contrast, while 5/8 inch plywood would certainly provide more support, it exceeds the minimum requirement and could be considered unnecessary for this application. Thus, 1/2 inch is the most appropriate choice, balancing strength with practicality for mounting the isolator effectively.
