Plywood backboard for BS EN61439-3 compliant consumer unit

George Frewin
Can a plywood backboard be used for mounting a BS EN61439-3 compliant consumer unit ?

The consumer unit itself is a non-combustible enclosure providing the cables are not rear entry through the plywood so I do not see an issue here but

there are mixed opinions on using such a scenario on other forums.

    Looks like fire retardant hardwood faced plywood (18mm) is going to be the better (safer) option here and hopefully keep the DNO happy.  Security of the fixings should not be a problem here.
