Hmmm,
That's a tough one Joe,
It's hard to say without a closer look at the Circuit Protection used in the Panel.
That is a Hold Card attached to the padlock on that locked out circuit.
My guess is Electrician on the left, Apprentice on the right. [Linked Image]
Mind you, with the colour/style of thier over-alls, I'm picking that is more than likely Australia than anywhere else. [Linked Image]
Even the Isolator (Disconnect)below the Pan Unit looks foreign to anything we have down here.
By the size of the panel, this is a Distribution Board, within a larger Commercial Installation.
Best people to answer this would be 32VAC or Gray.
