Best look to change wholesaler then Paul. What other cheap fake "carp" have they been chucking your way?
Those jokers are history, never going to use any of their branches. The other "carp" (cough), well lets put it this way. Any LED security lights I install are on a stand alone PIR and not a built in version.
Getting back to the Wago's, only buy them from wholesalers you know and trust and check the packaging. God forbid that any electrician on here uses a fake connection Wago and sets a house on fire! Check what your buying and using.
