They did say EMT and it was in a connector on the metal box end so PA would be grounded (as in operate the O/C device).
The usual method was a 10' stick, bent into a 90 at the top of the framing into the attic a way and they shoved the RX down that pipe. One thing that really made it nice for me was I was able to belly far enough into the low part of a 3:12 attic to slip on another EMT and tighten the connector. Then I could yank out the existing 14-2, set a J box where I could get to it, pull in THHN and add a circuit.
