Joining oven pigtail to NM-B 8/3g
What's the proper per-code method to attach a residential oven's #8 stranded conductors (in flex armor) to the branch circuit's 8/3 w/ground (stranded conductors)? This is a dedicated 4-wire circuit of course.
The splices are housed in a 4" square steel box (2-1/8" deep, 30cuin) with the grounds bonded to the box.
Thanks in advance.
