Summary I addressed some issues with the previous design : (thanks for the comments) 1 : The cables are seperated 100% by walls and a top that slides in to keep them seperated. The wires cannot touch now. 2 : Made a clamp that can be screwed down to hold the cable in place, provide some strength, also take away any chance of force being applied on the actual joins. 3 : The M4 bolts which hold the 2 outer pieces together have been moved from the centre to the outer edges, to prevent any wires from possibly touching the bolts and thus shocking a human. 4 : Ensure you don't use a flammable silicone or glue when covering the wires. use a non-flammable substance or epoxy.
