Actually not - the center conductor in an N is 0.120" - you might be thinking 
of the pointy locator pin in the middle (0.063"), but in a "properly mated" N 
connector, that's not carrying any power. 

In a BNC plug, the center pin is 0.053" in diameter (slightly smaller than the 
locator on an N) although i confess, having just looked through a variety of 
drawings on google (BNC dimension image), there is a HUGE variation. Just like 
in an N connector, you're counting on the mating surface at the shoulder of 
that pin to carry the RF current (and set the impedance) (typically 0.081 to 
0.087") and that's about 70% of the size of the N connector's center pin

********

So, if the connection on the N is just the flat donut contact, that is even 
less surface area than the BNC pin! So, e N have a lower power rating than the 
BNC?
