That's a tough one Joe,
It's hard to say without a closer look at the Circuit Protection used in the Panel.
a Hold Card attached to the padlock on that locked out circuit.
My guess is Electrician on the left, Apprentice on the right.
Mind you, with the colour/style of thier over-alls, I'm picking that is more than likely Australia than anywhere else.
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.
