In-Flight Electrical Fires Response

A short circuit occurs when the electricity is flowing along a different path than the one that it was intended to follow so our safety features such as circuit breakers and fuses cannot stop it. The short circuit will be particularly difficult to stop unless we shut the electrical system down because it will continue to flow.
The procedure in the Seminole follows along with what the article was getting at. The article was indicating the idea that just pulling a circuit breaker is not a through response because damage can still be occurring. The Seminole checklists calls for the electrical system to be shut down by turning off the battery master, alternator, all electrical switches, radio master switch, it then says to close the vents, and turn the cabin heat off. All of this is designed to make it possible to safely land the aircraft because continuing flight would be unsafe because now the aircraft is no longer airworthy.
The way I thought about electrical failures was that they were an emergency but not on the level of an engine failure but not as mundane as a alternator inoperative light. But my perception of electrical fires is that they are a much more serious emergency than I thought and when I handle one in the future it will be with different mindset and assertiveness to end the fire as soon as possible.
