I am just a first year electrical technologies student and have already learned that wiring laid in notches in wood studs, joists, or rafters also require to be protected by a 1/16'' steel plate,according to article 300.4 of the NEC. Even as a student still learning the code i see many violations in that photo such as no conectors on the box. also looks like the box is scorched where the yellow 12 AWG enters the box. Now that the new cable has been added the box it is now most likely too small for the conductor count allowed. But since there is no cover there should be extra room now right? haha. yeah sure!
