I have a question regarding determining the interrupt rating for a control panel in the US. In particular I would like clarification for the combination of inverters (or other equipment) with the manufacturer's recommended fusing. If the recommendation is followed does the assembly of the 2 components have the interrupt rating of the fuse? Similarly if I have a solid state contactor and fuse that limits the let through current to less than the inrush current resistance what rating does the combination assume.
It is my understanding that this is the case when type 2 coordination is done with contactor/fuse combinations the fuse rating applies. Does this work the same way or am I off base.
