Everything else being equal, it is the size of the wire that is most important. The breakers and receptacles can be upgraded, but, put too much current through the wires and you get heat and then you get the fire.

But that's kinda hypothetical and doesn't apply unless you are planning on making some changes to your electrical system. For practical applications, use P4B's formula.
