I would like to know the proper way to Install HCF MC cable. I have seen it done three different ways . The method where the redundant ground wraps around the cable seem like it would crowd the connector and put pressure on the cable , the other manufacture recommendation is to just cut it off as it passes thru the connector. the last method I have witnessed is to terminate them in the box , and bond them to the box leaving the insulated ground to be tied directly to the receptacle.
