I have 3 phase 480 power coming into a new building we are building. 200amp approx.
In this building we are going to use the 480 3 pahse and use a step down to run 1 phase 120/240
We are also going to subfeed the 480 3 ph to another building step down to 1 phase 120/240 for lights and misc.
From the second building we are going to sub feed our office with 100 amp of 120/240 power 1 phase
Each subfeed is about 120 distance from the next building.
Question:
Most tranformers I find are 480 primary with a 208/120 secondary on them. The 208 is no use to me.
Do these types of tranformers have two legs of 120 that can make the 240?
How do you get the 240 1 phase?
Do I need a transformer that is 480 primary and 240/120 secondary
