Default N power connector rating?

Without actually researching it I suspect the power handling capacity
will be similar to the 1/2" line itself. When a N plug mates with a N
socket it presents the same Z as the line with pretty well the same
diameters. ie the small pin is not carrying the whole load. The RF
losses and subsequent heating will be a function of skin effect of
course. How well the pin is soldered will probably also make a small
difference. Arcover will be an interesting discussion though as there is
an air dielectric where the pieces join..

I guess you could work it out from known resistance of metals, allowing
for skin effect and what will happen first, arcing or melting - all at
50 ohms and a bit of ohms law. Lets face it though you can go and look
at manufacturers websites for this kind of info.

Hardline of larger diameters than an N connector use DIN connectors or
anything else that is "larger". If you are really wanting to know go and
have a look at something like the andrew website for data. You can of
course also reduce to N size using a suitable fitting.
