The product is not faulty, it is in line with the standards required for rcd/rcbos.So when a product is faulty we alter the test parameters to ensure it passes?
not sure on the legalities of this.
the excuse is manufacturers instructions say to do this.
what takes priority b.s.7671 or manufacturers instructions?
if the manufacturers instructions are requiring a greater degree of protection or better disconnection time this is fine, but in this case it is not.
very naughty!
It's just people are not familiar with it, there is no absolute requirement for 150mA or 5x , the requirement is the figure as published by the manufacturer, it was just normally 5x but didn't have to be.
