The item in my kit

I bought SELTERM 4-AWG Quarter-Inch Cable Lugs as part of my camper van equipment.

My purchase list separates this quarter-inch-stud lug from the 5/16-inch version. That small hole-size difference matters when keeping similar-looking connection parts organized.

Where it fits my build

I brought the roof light wires and camera cables into a PVC conduit layout. That work included drilled enclosures, threaded fittings, cable glands, solder-seal splices and grouped wiring.

During the small-box stage, I drilled for a male PVC fitting and used a fitting inside as a retaining nut. I routed the camera cable through a gland into a tee and brought the light-wire groups toward the van entry.

My build notes

The wiring project was a sequence of individual connections and routes. The photographs show the intermediate stages, including open boxes and wrapped wire groups, before the remaining covers and conduit joints were finished.

I built the cable route a section at a time, bringing local connections into the larger conduit system.

Alternative products

Two alternatives to compare

The other SELTERM pack keeps the 4-AWG barrel but changes the stud hole to 5/16 inch, while TKDMR supplies a mixed-size lug assortment with tubing.

SELTERM 4-AWG 5/16-Inch Cable Lugs

These tinned copper ring lugs have barrels sized for 4-AWG cable and holes for 5/16-inch studs. Their ring ends provide a bolted cable termination.

Questions from my build

What connected the roof equipment to the van entry?

A PVC conduit layout with boxes, fittings and cable glands.

What did I do at the small junction box?

I drilled the box for a threaded PVC fitting and arranged the light-wire connections inside that part of the route.
