What’s the minimum wire gauge for a DSc keybus?
DSC recommends that the minimum wire gauge to use is 22 while the maximum is 18 gauge. They also state that shielded wire should not be used for the keybus. Modules on the keybus can all be on home runs to the panel or connected in a parallel series or T-tapped. Or any combination of those wiring options.
