Power cable education needed

If a manufacturer does not include and “adequate “ power cord....that being the gauge is too small to “adequately “ supply the said component with electricity..... there is another name for that power cord. It becomes a “light bulb”. So why would any manufacturer save money on supplying the customer with a power cord that was too small to do the job? This power cord argument makes no sense.

if you buy a larger gauge power cord than needed the component relies on the incoming fuse to protect it from getting hit with too much power. There is one answer...stay with the cord supplied by the engineers that designed the product. 
My favorite idea that I’ve read today is from my buddy MC....go with a larger power cord and a fuse with 2-3xs greater rating. Let it roll! I think I’m going to start audio grade fire extinguishers!

A fuse is an electrical safety device that protects an electric circuit from excessive electric current. Fuses are destroyed during overload conditions. When reasonable to do so (and economically sensible), circuit breakers are used instead because they are not destroyed during overload conditions. It's cheaper to install fuses than circuit breakers, but since fuses need to be replaced and circuit breakers don't, fuses have a higher operational 


where did I go wrong?

So then can you please explain to me what these giant power cords bring to the table? I purchased a couple and I couldn’t notice a difference. I’ve got good hearing and approximately 50 K in my system. I’m trying to figure out what a $10,000 Power cord brings to the equation. I’d love to have an explain to me. Thanks

Well than what do they limit?

I think I understand your point...I just can’t explain it. Let me try though, if you had a giant power cord, like half inch thick wires And a circuit blew inside the appliance it doesn’t matter how big the wire is before the fuse...It’s not like the large wire is holding a huge amount of electrical current as if it was water. The fuse was low and that would be the end of it. Am I close? Thanks for pointing that out
