Got into a discussion about securing T-Bar wires at both ends. Usually tied off to the T-bar. As far back as I can remember 300.11(A) states you need to tie off your wires to the grid but a journeyman I work with insists that he did many jobs by folding his wires up and not tying them off to the grid and that the code only recently changed that. Anyone have access to code books older than 2008 that have 300.11(A) ? My guess is that this has always been a code requirement to tie off your wires top and bottom.
