I've only had to work with this a couple of times but, in each time, I got different answers from those that seemed "in the know".
When installing a disconnect on the secondary side of a corner tapped delta transformer, does one need to fuse the grounded leg or install a dummy fuse in the jaws?
I've been told to fuse it since it is one of the three legs going to the equipment but, it's also the grounded conductor which would mean NO FUSE.
I can't find anything in the code about this.
Any help?
