Our lives can not be separated from the terminal, if the power cord can not be used junction nose what will happen?
Wiring nose, we called on the popular terms of the inside of the electrical cable connector. Wiring wiring nose, sometimes not.
In general, the pressure of what line the nose is set according to the current. General diameter of less than 10 square can be directly connected to the terminals. Note that I said, can not in strict accordance with the electrical requirements.
Wiring nose start fixed thread, because the strands sometimes is hid with screws, and pressure the the line nose makes cable more full contact, will alleviate peak current, will not spark. Usually vibration of the large power cables are very large. So do not line the nose is not, because it played its important fixed.
