The main fuses protect the feeder lines from the electric company's feed to the main panel for the maximum ampacity rating of the wire. So depending on the size of the incoming tails nothing is gained by reducing the main supplier's cut-out fuse rating to 60A or 40A.
To break the circuit if the temperature of it exceeds the rated current. Used in mains frequency transformers to disconnect it from the mains if it gets above a certain temperature to prevent it from catching fire.
... fuse.
A fuse or circuit breakers purpose in a circuit is to disconnect the circuit load from the voltage source when a circuit fault occurs.
NO! Using a larger amp fuse defeats the purpose of the fuse to protect the wiring in the circuit. This can cause a fire. Always use the correct amp fuse for that circuit.
NO! Using a larger amp fuse defeats the purpose of the fuse to protect the wiring in the circuit. This can cause a fire. Always use the correct amp fuse for that circuit.
The fuse protects the circuit that powers the transmission control module.
A fuse is designed to blow, should a short happen in a circuit, before the mains wires heat up and burst into flames - causing an electrical fire in a device or installation.
If you are talking about automobiles, the purpose is to show you what is being powered by that fuse. This is typically used to diagnose a problem with a fuse circuit to discover what is shorting out and blowing the fuse.
Because if it is not connected to both it is not a full circuit and therefore if it is not a full circuit then the fuse can't protect you.
To supply the bell, because the latter has a rated voltage that's lower than the mains.
Yes it has in the plug that you put into the mains.
The purpose of a fuse is to open an electronic circuit when current flow exceeds a certain amount, determined by the rating of the fuse. Opening a circuit under high current conditions can save electronic components from damaged and prevents overheating, which could cause a fire.
