outlines new requirements from Jan 2016 for either using CUs made on non
combustible material or enclosing in a "non flammable" enclosure.

Have the NICEIC (or anyone else) offered guidelines on what a non
flammable enclosure means?

eg would use of Euroclass B/C fire resistant plywood meet the regulation?

As an aside, here's an extract from the justification for the new
requirement:
"The cause of the fires investigated was almost invariably found to be
resistance heating as a result of poor electrical connections due to
poor workmanship or lack of maintenance."

Seems to me it will take a lot of effort to put in place regs to ensure
that *all* parts of any electrical installation are proof against
incompetent installers.

My limited experience suggests that it may be worthwhile to
periodically check the tightness of *every* wiring connection in a
house. Haven't seen many examples of overheating, but have come across
quite a few connections which seemed to have become less than tight.
