I am an Electrician, and I have never heard of 10A breakers. So I will tell you how we wire houses. A 15A breaker is normally loaded to 80%, IOW we allow 12 outlets on a circuit. for a motor we allow 300% for starting surges, so a motor drawing 5 amps would have a 15A breaker. But connected loads are not always on at the same time. So to give an idea about circuit loading in my house I have the following equipment on one circuit.
2x175W Mh lights.
1x150W heater
1x75W heater
1x60W heater
2xAC 301 powerheads
1xSeio 620
1XFluval 304
1xFluval 204
My computer + my bathroom, + room light etc.
That should give you an idea.
