Hi, I have a fairly good sized toroidal transformer that has two pairs
of primaries and two pairs of secondaries. The inputs are both 115V
and the outputs are both 33V, at 7A. I'd like to combine the outputs
in parallel, to give me 33V at 14A.
Connect the two secondary commons together. Now check across the other two
leads with an ammeter for difference current. If it's only a few mA you are
probably OK.
If he only gets a few mA, then the secondaries are phased properly. But what
if they're *not* phased properly. Whay do you suppose is going to happen when
he connects an ammeter across the other two leads?
