Supplier accepts its faulty . Wants me to post back the 300m roll - postage will be ridiculous- but they said they would cover cost of that . So I pulled out 30m from the stranded box - same supplier but different brand no issues . I think after this experience I will pull the length I need off the roll then install ; will cause more wastage - but I don’t trust any rolled cable now !
As I’m back in the market for solid core cat6 any recommendations??
