I hear you jdbob but the manual says to use a 25amp breaker which is why I wasn't thinking of putting in a 20amp breaker. I know it's drawing less, which is why I went with the CC LCS 4.8KWH instead of the HCS 7.2KWH. LCS was $100 less and, like others, I intend to keep this car for 5 to 7 years so getting bigger didn't make sense at this point.
