Q: Why does it have a neg and positive marking.. .usually you just interrupt the positive in this case with single pole?

Yes, usually you just interrupt the positive with single pole. DC is directional, so by marking positive and negative poles, and wiring according to the markings, you will clear that the DC direction is from circuit breaker bottom to top, which is easy to maintain.

Q: What end top or bottom does the load connect to on a single pole breaker ? The breaker has a plus sign and a minus sign that is useless.

The load is generally connect on the top of the circuit breaker, DC direction is from the bottom of the circuit breaker to the top.

Q: what wire size is accepted?

a wire size that is rated at 100amp.

Q: Do you connect the battery to the top or bottom ?

There are polarity markings on the body of the switch. I connected the dc power lines accordingly.
