Is it a violation of CEC to use NM cable in exterior conduit?

Not a pro, I'm just a dummy apprentice, but Table 19 is our conditions of use and NMD90 isn't listed for use a raceways or cable tray under any condition (wet, damp, dry etc.)

Okay another issue, maybe. He has a 120 volt light on neutral and one hot leg of a 120/240 circuit on a 30 amp circuit. Sound wrong. I know in the U.S. general purpose 120 circuits are limited to 20 amps. Not sure if this might be an exception?

It depends. I have wired saunas before that have the light is fed off the control of the sauna, which is fed with a 120/240 feeder. The switch for the light is directly off the control "board".

That would be a mfg. design and is probably protected by the board.

If it is straight off a breaker, it is wrong. Residential lighting is limited to 15A circuits.
