I am replacing a bathroom light fixture in an old condo built in the 70s. There is armored cable coming into the fixture from the wall.
From my understanding is that I need to do these steps,
1) Install an old work/junction box w/ armored cable connector and attach cable. 2) Attach the three wires (black to black), (white to white), (ground from light fixture to ground in old work box. Is that right and safe?
Do I have to voltage test to make sure my old wires can handle the voltage of the new light fixture wires without starting a fire?
Pardon my ignorance on any of this. This is my first time doing electrical work.
Am I safe doing this without starting a fire?
Let me know if I am missing any important steps. Thanks!!!
Work Complete Update - I had to extend the armored cable with an EMT connection and new cable as I couldn't pull cable out of the wall to reach to the newly located floating work box. No mc flex cable connection available at the stores to extend the cable so a EMT connection was used.
As instructed, tested for ground and also installed anti-short bushings. Connected wires and connected ground to the ground screws. Used CFLs to create less heat for the older wires in the walls.
