I am looking at a Delta-Wye with 480 on primary and 208/120 on the secondary. The transformer in question is Schneider's EX30T3HCUNLP. I came across this drawing in the spec sheet but I am not sure what to make of it. What is the significance of the numbers 1 through 7 that are tied to H1, H2 and H3 on the primary. Do terms like "FCBN" and "2.5% FCAN" play a role in determining what type of load the transformer can supply.
The NLP in the part number implies non-linear loads. This is a 30kVA transformer that will feed a breaker panel with 30 breakers. Although I might have 5 or 6 loads that classify as "non linear", but the remaining 25 breakers will more than likely just feed regular loads. Can this transformer power both linear and non linear loads, or do I need another transformer for normal loads?
