Prototyping and product development is always an iterative process — you rarely get it perfect on the first go. Good engineering isn’t about adding complexity, but about removing it.
These photos show exactly that: a direct comparison between a built solution and an engineered one.
In our early Powerlock distro prototypes, we used heavy cable harnesses to connect the 400A connectors to the main breaker — it worked, but needed tooling, cable, lugs, and skilled hands to build and fit each one.
Once we had two units out in the wild and gathered real-world feedback, we took the opportunity to do better: we designed custom bus bars, laser-cut and bent to our exact specs. They cost more per part than cable, but saved time, reduced assembly complexity, and delivered higher performance. These 6 mm copper bars can handle over twice the maximum possible load.
Next time you’re shopping for equipment, spare a thought for the quiet hours of design and refinement behind the scenes.
Is your next purchase built — or engineered?
