there are several products now available for routing NM cable offered as an alternative to stapling along joists etc. These brackets have multiple 1" holes available to string the NM through. Manufacturer specifies distance between brackets depending on application from 16"- 24" OC.
Question is if multiple NM cables are routed through one hole of a bracket through multiple feet of brackets does such an installation constitute "bundling," necessitating derating of the cables?
