If by 'cable wire' you mean Coax cable for the TV, or internet, then the answer is no. The power/voltages in the cable are way to low to produce a spark which is usually what triggers flame.

If by 'cable wire' you mean a cable carrying an electrical service such as 120V or 240V, then, if the cable is damaged by an accidental or deliberate cut which causes a short circuit from a hot phase wire or wires to other wires in the cable - such as to other hot phase wires in a 3-phase circuit, a neutral or a ground wire - then the resulting heavy current could result in the cable becoming very hot and could cause it to catch on fire unless there was some overcurrent protection device to prevent that from happening.

That is why fuses and/or circuit breakers should always be included in any electrical service wiring to cut off the supply of current before a fire can be caused by such damage.

How can I safely and effectively cut cable wire without causing any damage or injury?

To safely and effectively cut cable wire without causing damage or injury, follow these steps: Turn off the power source to the cable wire. Use insulated tools to cut the wire. Wear protective gear such as gloves and safety goggles. Make sure to cut the wire cleanly and avoid any nearby electrical components. Double-check that the power is off before cutting the wire.


Can a cut electrical wire cause a fire?

If the exposed wire grounds out and a great amount of heat is produced then yes a fire could start under this condition. Remember overhead transmission wires are exposed wires but are well insulated from ground so as not to have the above scenario happen.


Is it safe for me to cut a cable wire?

Not enough information. If you mean an electrical cable, no it is not safe unless you have isolated it and verified that it is no longer "live"!


Why extra cable is needed in wiring process?

Having extra cable at termination points is a good practice to get into. If a wire burns off of a termination point or the wire burns back on itself the whole cable does not have to be changed out. Just cut the wire in the cable back to the undamaged section and reconnect the wire. Without this extra length of cable the consumer will have to under go additional costs should a failure occur.

What is a cable crimper used for?

A cable crimper is commonly used for bending or crimping thick wires. They may also be used to get a better grasp or to cut the insulation around a wire.


What do UltraDMA66 and higher require?

UltraDMA/66 requires a special ribbon cable with extra wires (80 wire) to cut down on crosstalk


Why the fuse wire reduces the danger of fire in a building?

A short in an electrical circuit could cause the cables to become red hot, causing an electrical fire. Before the cables begin to heat up, the thinner fuse wire will blow, or a breaker will trip, and the circuit will become open before any damage occurs.
