Quick question on stacking variacs??


Say I had a 3-Phase stack of variacs all connected via one shaft and each
one rated at 115VAC, 10A.

Would wiring them in series yield a say 345VAC, 10A variac and wiring in
parallel yield a 115VAC, 30A
variac???

Not sure what the common practice was in stacking variacs.

Thanks
Dan
