ECN Forum Forums General Topics of the Trade General Discussion Area Buck Boost Transformer on an oven

Edward:

I'm curious what voltages (both L-L and L-N) you got. Is your voltage ratio (L-L to L-N) 2 to 1 or 1.732 to 1?

PDH,
I can't remember what the lower voltages were, I know that it was not a true 120Volt. When the buck and boost is used for double pole boosting or bucking the lower voltage is very odd.
For example:
Boost 208-240.
L-N Might be 134V
L-N Might be 109V.

Whenever i do these installations i always mark on the panel that (the B&B transformer is feeding) 120Volt is not available.
