I'd say they're wrong.
Type Ns flashover at >3000V at STP, and that's a lot of voltage. The center
pin can handle 6A continuously, probably 12A intermittently. 1500W is 5.48A
in a 50 Ohm system. 1500W is 273.9V in a 50 Ohm system.
I don't see the issue. I've used type Ns at 1500W output power on 70cm for
eme work, and never had one fail...

Subject: [TowerTalk] Power limitation for N-Connectors
Setting up a vertical on 40, but about 300 feet from the shack. Plan to
use used 1/2 inch heliax LDF4-50A. Someone, who might be wrong, said N
connectors are limited to 500 watts. That's probably at UHF/VHF
frequencies...but got me wondering. Actually I would prefer to use
PL259/SO259's, but would have to round up those connectors (L44U's).
Any problems re N connectors for full power below 30 MHz?
