@everetra - I agree. I think that everyone could use a little education about electrical loads and amperage. You don’t have to be an electrician to figure it out.
Sometimes you learn the hard way, like when you attempt to install a high powered light bulb in a low powered bulb and the thing blows up.
I work in the electrical utility industry and we work with circuit breakers all the time. They are mission critical devices, along with overcurrent relays, which prevent electrical spikes from happening.
All short circuits basically take place the same way. They basically open up the circuit so that it no longer receives electricity. This is true whether you’re talking about a fuse in your power supply cabinet or a protective relay in a substation.
