I keep getting a solid red light on my Blink HQ EVSE. I'm using a dryer outlet on a 30 amp ciruit breaker. I bought a pigtail for a dryer and attached it to it. All contacts look good. Doubled the ground with the neutral, since no dedicated spot for that neutral. When i turn it on, all lights cycle, but then stops in solid red. Critical fault is what the manual says. It also recommends that it should be on a 40 amp circuit breaker. Is that why I have a fault light?
