Securing 8/3 cable, are flat metal staples acceptable?
Have been using flat metal staples on 14-2 and 12-2. However, they're large enough for the small amounts of 8-3 being used in exposed areas of crawl space and unfinished garage. Provided care is taken not to hammer them down to tight and to keep bends in cable to a minimum, are these considered acceptable by NEC or otherwise? Thanks for feedback.
