I've never really used power connectors before. I am working on a project and saw there are power connectors in it. We had some issues and changed the manufactured power connector to a 30A power connector. The system definitely needs more than 30A. Does the 30A really matter? Or should I buy a 60A connector instead?
Of course it matters. You need to give more information though. Current requirements, power requirements, voltage requirements, which connector you are talking about. If you pull 40A through a 30A connector there is a good chance of failure. It's also possible that nothing wrong will happen and the connector is just hotter than normal. We can't answer this without more info.
