Dear all

I just got a blue seas 40A thermal circuit breaker to protect my main
panel feed. I was surprised to see that the terminal are marked 'batt'
and 'load' or something similar. Because the wires are thick and space
is tight it would be easier to connect it the other way round. Is
there really any polarity to this ? Would it make any difference which
way round it was connected ?

Thanks

Steve
