The item in my kit
I bought Siemens Q115 15A Single-Pole Breaker as part of my camper van equipment.

Where it fits my build
On Day 104 I pulled the roof wiring through the PVC route with fish tape and brought the cable groups into the van. I fitted plastic trim around the roof opening where the wires passed through.
I also finished the remaining light-wire connections, fitted the junction-box covers, joined the remaining PVC sections and tightened the metal ties around the route.

My build notes
This stage pulled together several earlier sessions of drilling boxes, fitting glands and arranging the roof hardware. The final cable entry was the point where all those separate roof routes met.
My notes show how much of the work was physical organization: pulling cables, keeping entry points accessible and closing boxes after the connections were finished.
The route into the van was a layout problem as much as a wiring task.
Alternative products
Two alternatives to compare
The QF115A adds ground-fault detection, while the QA115AFC adds arc-fault detection; these are different breaker functions within Siemens' 15A options.

This single-pole breaker combines a 15-amp circuit rating with ground-fault detection. A test button sits beside the operating handle.
This single-pole breaker includes arc-fault detection alongside its circuit-breaker function. The body combines an operating handle with a test control.
