Circuit marking
Blue lever nut wire connectors
Blue levers are often used for neutrals, signal lines, or cool-toned circuit marking so related conductors stay grouped visually.
Common uses for blue wire connectors
- Neutral or common conductor marking
- Signal and sensor lines in garage door installs
- Cool-tone circuit ID next to warm power colors
Why choose blue lever nuts?
Color-coded blue lever nut connectors make splices faster to read later—especially in vans, campers, shops, and trailer harnesses where many conductors share a box. Pick blue 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.
