Does the Z4000 have a separate breaker for the 10V circuit, or some other feature that would cause breaker to trip at a lower current from the 10V circuit?
Wouldn't that be for a resistive load only? Many times when testing trains on the bench with a Z, at lower voltage, the current is higher. If there is a power consumption, higher voltage requires, less current to = same power. G
Correct. I think you need to consider Watt's law. Some devices draw the same amount of power (watts) to operate. If they can't get it from volts, they get it from amps. These are non-resistive loads.
