Just making the panel into which the consumer unit will be fitted along with a 60A switch fused unit and a distribution block. Wondered if I can make this panel out of OSB / plywood or if it needs to be specifically flameproof. Reading the regs it looks like it is just the consumer unit that has to be metal but the 'and similar switchgear' catch all is a worry. Essentially it is a box in one of the internal walls that will house the CU accept the in coming cable and take the outgoing cables away. The switch fused unit is for the in-line water heater.
Any insights?
