Hot water heater electrical

[Gary G™]

The electrical supply line coming out of the drywall ceiling into the top of the heater isn’t in conduit.
What’s involved in removing the connection at the top of the hot water heater in order to slide conduit over the Romex?

Unscrew the cover plate, probably untwist wire nuts, unscrew the equipment ground. (Edit: probably an untwist also, not an unscrew - all pretty simple).

Assuming 240v, #10 10-2wg.

If so, you would need 3/4” flexible probably??
If it is 10-3wg then I think you’ll need to go to a1” conduit.
(@53% fill... if I read it correctly, someone else could correct me).

Edit:  if you want a more reasonable conduit size, 1/2”, consider adding a junction box at the ceiling and transitioning to thhn

No one here uses conduit.

But then again, no one ever uses a stress connector either.

Must be a local code as they want it here also.   They are normally open at the top, conduit box connector on top of WH .  Just a sleeve for protection ?   Roly
