Hello everyone

I am installing a new wall chimney kitchen vent hood. The wiring for the hood includes ground, but the existing wiring for the old under microwave vent only has 2 wires with no ground. The wires are in the metal armor conduit, and my buddy mentioned that this metal conduit is the ground.

Is this true? If so, what do I do with the green ground wire from the vent? Electrical tape it to the metal conduit?

Thanks for any help you can provide

Thanks, I will go later to check if it has a grounding strap inside of the outer sheath armor.

If it does, is this ok?: attach a box to the stud. Clamp down the armor outer sheath snugly with the grounding strap bent back on the sheath for a positive ground. Attach and wire up a single outlet 15a GFCI receptacle. Use a short piece of 14g wire from the box ground screw to the receptacle ground screw to ground the receptacle. Attach a plug (including green ground from vent) to the vent wires. Hang up the vent and plug it in.

House was built 1964. From what I remember when I briefly looked at it last night, there was brown paper inside of the outer sheath around the wires, I didn't see a grounding strip but again, it was a very brief look. I will look harder when I am working there tonight.

So if it does indeed have the grounding strip, would it ok if I: attach a box to the stud. Clamp down on the metal outer sheath snugly with the grounding strip bent over the outer sheath. use twist nuts to bond the power and neutral wires. Attach the green ground wire from the vent to the ground screw on the box.

Thanks for all the help you are providing
