Panel Insertion – Channel 10×10 mm
An easy way to run 12 v cables inside the core in a 29mm composite panel . Channels are cut 10mm wide and 10mm deep in the XPS core
Channels usually run from one edge of the panel to the opposite edge.
DIY Caravans recommends only insert cables where necessary and try to bring services from chassis up the back of cabinets in surface mounting trunking where possible.
