Question about disconnects
Question about disconnects
I apologize first of all, because, I can't find how to start a new thread.
My question relates to disconnect switches.
In any building that has fault current over 14k, we always call for all disconnect switches to be fused. This is because, if you look at the GE Buylog or competitors info, you find that disconnects without fuses are rated for no more than 14K.
What we invariably get, is an unfused disconnect at the equipment, provided by the equipment vendor. We squeek and we squak but the truth is we often end up with that as our disconnecting means.
Should we be pushing this issue more vigorously. Are we overlooking something? Are these unfused disconnects at the equipment ok. e.g. include really all HVAC equipment but it's often an issue with AHU's, Crack units, etc.
Interested in all thoughts.
