Question:
Hi Charlie:
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.
Thanks! Mike

Answer:
Hey Mike thanks for your question and the compliment. Correct, there is no specific reference to 300.11 or supporting rules for the wiring methods in 725.3 as you mention. If the Class 2 circuit is used for power and data (POE) then 300.11 is referenced in 725.144. There is the neat and workmanlike rule in 725.24 but it is not specific either.
Also make sure the Class 2 wiring in the PVC conduit is suitable for a wet location because that is required as stated in 725.3(L).
