Disconnector Extension Shaft
Disconnector Extension Shaft
(OP)
Hello
I have a question: when is required that we use a extension shaft for disconnectors?
Here, we always use on the machine panel door, but if we instal on the side, do we have to instal with a extension shaft too? Or its not required?
I haven't found a standard that said loud and clear in wich case it is required.
Attached if a picture of the disconnector with the extension shaft.

You obviously don't need it when you put the handle directly on the switch/breaker/fusible.
Putting the switch/breaker/fusible directly on a door means the higher voltage 3-phase power is wired to the door which is simply not safe, even if it's allowed by local codes and standards. So, check your local codes and standards and see what they say about wiring the main 3-phase panel power (the 380V/480V/600V etc) to the door.
So, put the handle on the door and the switch/breaker/fusible on the back panel with the rod connecting them and you don't have the above issue.
Enclosure side wall mounting also avoids the above issue without the need to use the extension rod.
