Lockout tag out is complyed with . Does arc Flash come into play?
If feed to motor is loto,within site and confirmed off, I would say no. The disco should be opened and the load side checked and confirmed (by more than 1 method and tool),This would not require AF protection either IMO, based on the fact the line side has the arc shield in place.
On a side note, (not to hijack).
I came across a VFD repair this week,Someone else started the repair. I did my visual then test, I noticed they LOTO the 100A disco on the LOAD side of the VFD!
So apparently they were lucky, Because the line side (200A 480/3P) was still HOT!!!
This leads me to believe that the individual was NOT "Qualified" to work on it.
