OpenEVSE had both the Struthers Dunn relay and Packard Contactor in UL labs for testing. The Packard ran a few degrees C cooler and ran a full 6,000 cycles in the durability test. The Struthers Dunn configuration ran hotter and failed after about 1,200 cycles. We are not yet sure if it was the relay or electronics that contributed, but we have the sample back from UL for diagnosis. 

We are working to update the guide. In the meantime, Steps 4 through 8 can be followed here:

The OpenEVSE kit and assembled version of the kit will likely never be certified. This allows us to innovate, add new hardware and new software features. Certification would lock us into a defined hardware configuration and lock many of the software modules. Essentially, OpenEVSE would be frozen in time.

OpenEVSE does provide hardware and engineering services to our customers to certify their configurations. Through these efforts we receive a bunch of data and can make improvements to the OpenEVSE kit.
