Redarc 40 amp DC to DC Charger issue
After about 15 seconds or so when I start the engine my shunt reads up to almost 49 amps and then the 60 amp input breaker pops. Whats going on here? Isn't the charger supposed to limit the output cur...

Forgot to mention this previously. Something that needs to considered when electing to turn on a dc to dc charger based on ignition voltage (vs. alternator output voltage) is potentially reduced current to the starter while starting the engine. As soon as the ignition is turned on, a 40a dc to dc charger could be drawing as much as 60a from the battery. On some vehicles that 60a reduction could impact starter performance---especially in extreme cold/hot weather conditions.
As I recall there is a delay from when the ignition is activated to when the charger passes current.
Delay is about 30 seconds and then it ramps up the amps over about another 30 seconds.
