Ground
Black lever nut wire connectors
Black levers are commonly used to mark ground conductors so splices stay easy to identify in panels, junction boxes, and DIY harnesses.
Common uses for black wire connectors
- Ground returns in 12V van and camper builds
- Neutral or ground marking in shop lighting runs
- Matching black jacketed cable in trailer harnesses
Why choose black lever nuts?
Color-coded black lever nut connectors make splices faster to read later—especially in vans, campers, shops, and trailer harnesses where many conductors share a box. Pick black for each lever that needs that role, then mix in other colors for the rest of the splice.
Available on compact lever nuts (2, 3, and 5-wire) and inline lever nuts (2-wire), all with tool-free levers for 12–24 AWG compact / 12–20 AWG inline splicing.
