We recently had to boost 208v to 240v for a kiln. We were not sure how to wire the transformer and got help from someone who knew how but not why. Well I’m curious George. I want to know why. On the label it says for a 32v boost connect h2h3, connect x2x3. That was easy, just wire nut H2 to H3 and X2 to X3. Now the part I don’t get. It says ON LINES H1-H4 and X1-X4. What we did was this
208 to 240. H2-H3 Tied, X2-X3 Tied,
X1 is one of the Primary 208 [Line] & goes to one pole of double pole breaker.
H1. Tie 2 to wires to H1, so there are 3 wires Tied. One goes to Primary 208[Line] the other pole of double pole breaker & one goes to Secondary 240 [Load]
X4-H4 are Tied with another wire that goes to one of the secondary 240 [Load] so there are 3 wires Tied & 1 goes to 240 [Load].
Question – Why does this work and how can you tie a primary & secondary together - X4-H4.
Thanks for your help.
