Ok guys here is the scenario...Installing a new 20 amp breaker in service panel from which will be connected 12/2 romex..This romex will lead to a junction box, connected using the appropriate attachment...exiting the junction box will be 1/2" emt ,also connected with correct attachment, which will lead to a 20 amp receptacle enclose in a metal box. Now the question here is, when running thhn through the emt from the receptacle to the Jb I will be including a green wire as well, which has been also connected to the green ground screw in the metal handy box at the receptacle end by way of a pigtail. The bare ground in the romex will be connected(pigtailed) to the green ground screw in the junction box and of course the green thhn running to the receptacle....Now I'm under the impression that this setup complies with NEC requirements regarding safe grounding and bonding of the raceway or emt....Would I need to further bond the emt as it enters the Junction box by way of a grounding bushing to ensure continuity?
