No originally when I drew up the diagram I was going to use 4 separate outlets, instead I used regular 20 amp outlets and cut the bridge in the middle. So the 4 on each side are the outlets. Only two of them use the SSRs for the element, both are controlled by one PID. I know what I did, however I'm not good with the wiring diagrams. More or less there just for me to visualize. Sorry for the confusion.
