AMD 3: 2015 DPC

Have you read it yet?

I can't get access....

Yes, not too exciting.

You need to log on to IET to access it.

Maybe you are on their blacklist

not too exciting.

Apart from the bit about non-combustible consumer units. So they're all going to be metal-clad? With big ugly metal-clad lids?!

That and the Cmax factor which reduces the max EFLI allowed on every circuit.

Any one got a link to the DPC please?

That and the Cmax factor which reduces the max EFLI allowed on every circuit.

421.1.200 Switchgear assemblies including consumer units shall:
(i) have their enclosure manufactured from non-combustible or not readily combustible material, or
(ii) be enclosed in a cabinet or enclosure constructed of non-combustible or not readily combustible material.
NOTE 1: Ferrous metal e.g. steel is deemed to be an example of a non-combustible material
NOTE 2: For the purposes of this regulation insulating material e.g. plastic meeting a 960 ºC glow-wire flammability test as
defined in BS EN 60695-2-11 is considered to be an example of a not readily combustible material.


I wonder if current plastic CUs comply with note 2?

 

[mfarrow]

Unless otherwise specified in the relevant specification, the test specimen is considered to
have passed the glow-wire test if there is no flaming or glowing, or if all of the following
situations apply:
a) if flames or glowing of the test specimen extinguish within 30 s after removal of the glowwire; and
b) when the specified layer of wrapping tissue is used there shall be no ignition of the
wrapping tissue.

So really, dunno, but there's lots of variation out there. It's going to make EICR's interesting, unless the ESC choose to avoid coding against it.

Some do, many (the usual suspects) don't.

Proteus and the other CEF carp?
