Rules and regs with regards to the type of material used to support electrical apparatuses.

A customer is moving into a premises which has recently been tested and passed as requested.

I noticed all the gland holes, DB partitions and missing panels are covered using 12 mm plywood.

Rules regarding the type of material used to blank off or mount electrical equipment ?

In some countries you are not allowed to install a plastic DB it must be a non flammable material.

I was watching a video of a solar installation and the lad even goes as far as mounting the inverter and components to a board which is non flammable.

I like the way they fit a document holder below the inverter.
