alozzy said:I know it's not to code, but in retrospect I should have ordered my Zencar EVSE with a 26A setting, rather than the 24A setting, for my 30A circuit.
At 24A, the cable never even gets warm. Also, the 14-30R is right beside the panel, so it's a super short run. I realize 26A exceeds 80% of 30A, but I seldom if ever charge for more than 3 hours continuously, usually for less than 90 minutes.
24A is safer though and provides 87% of the full charging rate, whereas 26A would provide 95% of the full charge rate.
As jjeff mentioned, the actual draw, shown on the Zencar's display, is always a bit under the set point which adds a margin of safety
I liked my Zencar EVSE and used the 24A setting on a 30A circuit many times until it failed to live up to it's IP55 waterproof rating and died. It was under my carport roof but must have gotten some rain splashed on it. I was shocked to find out that Zencar does not consider failure of the supposedly waterproof case to be a warranty replacement reason.
Bottom line, do not expect a Zencar EVSE to survive being rained on even though it is supposedly waterproof.
