Plywood backboard for BS EN61439-3 compliant consumer unit

George Frewin over 5 years ago

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.

and the wall is masonry, you could fix it direct.

You could, but what if the wall is stone and you end up with just two fixings and the CU distorted due to the uneven wall? I know you could use resin fixings and packing washers etc but what aspect of using a ply backboard wouldn't comply?
