Safe Isolation Procedure of a Single Phase Circuit | PTT

[@TheDeno786]

This was helpful thank you .. i understand the cover shouldnt be off but that is obvious main concept was to prove isolation and how to do it

[@modeen3453]

Wait do we lock off first? I thought we do that at the end once we proved it was isolated?

Not good example to start with the cover off at least turn off first
