The item in my kit

I bought Four-Post Covered Bus Bar Set as part of my camper van equipment.

The four-post set is one of the compact stud-based layouts I bought for the van. It is listed separately from the six- and eight-stud distribution bars in my equipment collection.

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.

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.
