At the stroke of an amendment are all those CU's that have been installed on the back of the 17th edition now non compliant and will they have to be replaced:biggrin::biggrin:. I sense another load of customers getting stung again
Why is it the electrical industry seems to be more prone to knee jerk reaction changes from the powers that be without any analysis of the information presented to them, LFB has spoken and the IET has jumped in feet first

You’ve only got to read some of the threads on here to see that some of the unscrupulous so called “electricians” will be using this as an opportunity to fleece customers.

Funny how things turn full circle given time.
That Wylex CU in all it's different configurations was revolutionary when they first hit the market in the early 50's!!
I'd like to see what happens to the frame when tested with this 960'C test wire, because i've tried to burn this treated and matured hardwood frame in the past.... Unless this wood was in constant contact with the red hot burning embers on the fire, there was no chance, and even then was reluctant to continue burning, preferring to glow and carbonise than to burst into flames!!!
I do not know the test setup for the glow wire test ... but if the wire were only held at one end I expect it might bend. Testing modern plastic enclosures @ 960°C must be like putting a hot knife through butter!

Ha. Wouldn't that be ironic if it did pass.
So Maybe those old wood frame Wylex boards could still pass the Amd 3 tests then... lol!! The internals and the original covers were made of a bakelite material, so they would definitely stand up to the 960'C Glow Wire test....

It would not surprise me if they did via the non-combustible route according to the test criteria that Damien published. Therefore another example of 'non-combustible' according to the relevant standard. I find it hard to believe that a 'glowing wire' can concentrate sufficient energy at its tip or even along its length to ignite solid timber.
The 960°C test is three turns of nichrome wire wrapped around the test piece. The rest I’d have to look up regarding time, wire spacing and test piece size.
