I am in the process of getting materials together for a project I have going on.
Essentially the run down is the following:
480v 30KV Delta primary to 380Y secondary for a single piece of equipment. The transformer will be roughly 10-15’ from the panel it is being fed from.
I am going to feed the transformer from the 480/277 distribution panel in the electric room off a 50a breaker which covers the 125% OCP on the primary side.
I was planning on installing a disconnect with 60a fuses on the secondary side to cover the 125% OCP on the secondary side. This transformer is going to feed a single piece of equipment with 40a of OCP.
Does anyone see an issue installing a 2nd disconnect with 40a fuses to feed the new piece of equipment? It would be fed from the 60a disconnect that is connected to the secondary side of the transformer.
I’m trying to avoid installing a main lug load center for 1 piece of equipment to keep costs down for the customer. Or am I overlooking something that could be another option?
Thank you!
