Only Issue with those connectors I see is the daisy chain. I see them all the time with equipment I work on and per spec. every third connector needs separate feed. Even then will see burnoffs at the feed point. Being screw type connectors thermal expansion from high current loosens them over time then they melt. Mostly 24vac control inputs in what I see but they are not good for resistive loads. Also try using solid wire skipping every other one on the feed side. So you would have to inputs next to each other then daisy three then repeat for each one so they staggered. Still for the low buck option that's a good start.
