I'm using the current up to date receptacle as this is a new range. My question is this, I have used a metal electrical box, do I need to tie in the bare ground to the box itself? There is no green screw or clip to be found.

It does if it is NM cable. __________________ Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
