Ok, so I piped some low volt landscape lighting transformers, 3 of them to be exact 300 watt 120 volt. So here is my code question should I have treated these like any other transformer and used some sort of flex instead of emt for the vibrations? I never thought about it till it was done and looked at it and thought "whoops!" Is this installation a code violation? Or a probable service call?

Thanks in aadvance,

I doubt 300 watt transformers will vibrate enough to break EMT, particularly if they are rigidly mounted.
We usually see those connected with RNC tho if not carflex. EMT will rust out pretty fast down here in the swamp.

Thanls...I thought transformers HAD to be wired with flex (guess that's how I've done everyone), I just didn't think of them as transformers on account of ehh low volt stuff 😁
