ATC panels

[Pneumaticsman]

I have a question about the ATC breaker panels. Can we use just 1? Because in the diagram on the first website has it using 2. So do we have to use both, or can we use just 1?

Thanks

You may use one or both as your design requires. Although the electrical diagram shows a daisy chain wiring for the primary wiring, if you use two panels do not daisy chain the wiring.
