Sometimes if I have a 3 or 4-gang plastic nail-on switch box that has a bunch of NM cables, when I'm making up the box rather than using a big blue wire-nut for my grounds I'll separate the grounds into 2 groups and use red/tan wirenuts instead, especially if there's 2 circuits in the box. This configuration may not comply with current electrical. Learn how to connect equipment grounding conductors to receptacles and keep their continuity in boxes. The basic rule achieves this through an equipment grounding jumper; four exceptions. A grounding terminal or grounding-type device on a receptacle, cord connector, or attachment plug may not be used for purposes other than grounding.
