What is the output power of National NN-C2000P microwave oven?

There is an internal short circuit.

The transformer is probably drawing too much power by a low resistance or a short somewhere on the secondary's side. The components on that side include the HV cap, the HV diode, and the magnetron all of which should be tested. I would try the cap first but make sure you discharge it before operating on it.

Hello, Vishal -

I have not yet found a manual for a National microwave model NN-K577F online.

The National brand was a subsidiary brand of what is now known as Panasonic. National brand kitchen appliances stopped being manufactured in 2008.
Source of information:
https://en.wikipedia.org/wiki/National_(brand)

The Panasonic company may hold a copy of the user manual for the NN-K577WF model in its archives, however.

Panasonic is headquartered in Japan. However, unless you reside in Japan, I suggest you contact the Panasonic division located where you reside:
https://www.panasonic.com/global/support/get_support.html

On the home page for the Panasonic division in your country, there should be a Contact Us link or a Live Chat link. Ask if the company Archives holds a copy of the manual for the National microwave oven NN-577WF or the Panasonic microwave oven NN-577WF and if you can obtain a copy. Note: There may be a charge for a copy.

Best wishes.

I would suggest that contact the dealer from whom you purchased the oven or call any number listed on the model tag of the oven.
