Thanks for all you do with the code question of the day.
On a recent job class 2 wiring was installed in PVC conduit to protect the wire in a wet location. Does strapping requirements apply for a conduit system if used for class 2 wiring. It is a bit grey, but it would seem to me it would. 725 does not require adherence to chapter 3 wiring methods for class 2 unless specifically stated.
