Looks like the difference between 20 amps and 25 amps is about 4 miles per hour of charging. Is this thing safe at 25 amps?

I mainly want to know what is safe to run through these openevse units. Every picture I see on the internet show them set at 16, 20 or 24 amps.

I think the OpenEVSE capacity is limited by the relays and wiring used internally. I just bought one from GlennD that uses the same 80 amp relay from the Juicebox, and I'm running it at 40 amps. The kit sold on the OpenEVSE website uses 30A relays and fuses, I believe. The software itself can handle up to 80 amps.

Yeah, the software is consistent with the J1772 standard. Did I say something wrong?

I noticed today that the unit reset to Green mode. Does that mean I have to set the delay timer each time I want to charge? Is there any way to set the delay timer as the default status?
Thanks!
