Hi,

Im not an electrical engineer, not even close to one, but I have been asked to design a terminal for a motor. I have the power (current and voltage) requirements so I need to work out what area of copper in the terminal will handle this power.

Can anyone give me the equation, or point me in the right direction to get this figure?

Regards,

James
