I've seen many more 'degraded' steel CUs/switch fuses than I have plastic ones. Holes big enough to put your hand through in some cases.

Yup they get eaten with rust in external boxes.I've seen many more 'degraded' steel CUs/switch fuses than I have plastic ones. Holes big enough to put your hand through in some cases.
Not sure plastic boards were ever 'first allowed' in that sense. Up until the 18th there was nothing in 7671 about the material a CU could be as far as I know.One person's engineering judgement may differ from the next and that's fine, as long as the fundamentals are met. It could be an excessive application of 132.16 BUT equally it could be a valid application depending on the points put forward.
Another way to look at is its been considerable time since plastic boards were first allowed (16th? I don't know but I'm guessing close to 20 years?) and plastic does, over time degrade, even on a molecular level, so the drive to change to metal is a valid one (product life expiration).
Some would say its using a sledgehammer to crack a nut but if the end result is a safer installation, is that not the end goal?
Kids do lots of stupid things that they know they shouldn't, and sometimes forget and do things by accident that are dangerous.Would it not be prudent to teach your kids the dangers of sticking a fork in the toaster rather than relying on something that can fail
By this logic trunking, conduit, MCB's, RCD's, meters, all light switches and sockets, clips, cleats....etc etc, should all be metal.One person's engineering judgement may differ from the next and that's fine, as long as the fundamentals are met.

Bakelite has thermosetting properties and you could argue it is compliant to current requirements.Maybe we can bring back Bakelite ?
