The item in my kit

I bought Trisinger 20A Inline Solar Fuse Holder as part of my camper van equipment.

This Trisinger purchase belongs to the solar connection supplies in my kit. The roof diary documents the wider cable-routing project, including the junction boxes and conduit leading into the van.

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.
