Interlocking Electrical Enclosures
Interlocking Electrical Enclosures
(OP)
I am working on a project that has one main electrical, and four sub-enclosures. The main houses the main disconnect and fuses. In the sub-enclosures theres fusing for the enclosure and motor controls (motor starters).
My question is this; in the main enclosure the disconnet interlocks the door (it's a shaft style disconnect), but in the sub-enclosures the disconnect does not interlock the door(s). So, is it required that the door(s) be interlocked?

In the US if you are going to carry 460 through out the enclosures, which you seem to indicate by saying motor you have motor starters in them, you have to interlock. I do not believe a special tool eliminates this. Rittal has a special key to open their doors yet they are still interlocked. And do forget the assortment of warning signs you are required to use.

In our plant, we have key switches that can bypass guard switches (schmersal)of any electrical panel. Only qualified personnel has this "universal key". This is important when troubleshooting the panel or the machine specially if the application is critical or that can destroy product being run.
