The bells of the PVC are heading up toward the junction box, and because of clearance issues it would make more sense to feed . For junctions in walls or ceiling voids there are similar junction boxes with built-in connectors. Where those cant be used, UK electricians commonly uses unanchored screw-terminal blocks and, as you describe, just scrunch the wiring up to fit back in the box. Re: Terminating stranded wire on a circuit breaker You could also strip off about 1" of the insulation, pull that off, then strip off about a 1/4" piece of the insulation, and slid that to the end of the wire. A few twists, and a loop, and presto! you have a "contained" wire, ready for termination under a screw, looping the wire around the screw. I am upgrading my electrical box with more circuits, and circuit breakers. I would like terminate all the unused circuits wires in the electrical box panel with dummy circuit breakers rather than leave them dangling in the box.
