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?
