Give us a Drawing of what you're doing.

One in parallel would be 400w, one in series would be 200w,across a 120v single phase supply, delta is for 3 phase.

I am going to draw a picture, how did you come up with that? Did you use Rt= R1+R2+R3? For the one in series and Rt=1/1/R1 + 1/1R2+ 1/1/R3 for in parallel?

I figured it out the one in series output is actually 400w r1+r2+r3 =108ohm's 208 squared divided by 108 is the power output.
