Wylex RECSW2S

Zoomup
This is a 100 Amp 2 pole switch with enclosure to suit meter tails.


After having taken a small sample of the plastic enclosure, and holding it in a pair of pliers, then applying a small cigarette lighter flame.....


the sample burned giving off black acrid smoke and it did not self extinguish.


Should we be concerned?

    I disagree Alan. The material appears not to contain any fire retardant, which would make his flame test very difficult if it were present in the correct quantity. We are not trying to stop fires due to a hot wire here, it is against red hot connections with a significant thermal capacity, not very different from a direct flame, which could also occur from the cable insulation burning. It appears at first look that these things are unsatisfactory, which could be interesting! I have a slightly nasty feeling coming on which I will explain later because I have just realised why the fire retardant may have been left out of all those CUs too, because the retardants are on another "wee list" as they say. I am going off to check.
