A four wire cable is one that has four wires in it. Usually a red, black, blue and a white wire. When talking about cables the ground wire is never counted because now a days all cable sets have ground wires in them and are sized to the capacity of the cable's ampacity.

∙ 11y ago- yes electricity cables does have 4 wires inside them cable generally give extra safety against unprecedented electric shocks.

∙ 10y agoIn your house the cables in the wall etc. are normally 'live' and there is full voltage on them. The current flow when everything is switched off is negligible, perhaps 100 microamps.

Which characteristics describe most nonmetals in the solid phase?
Solid metals are often shiny, ductile(can be pulled into wires), malleable(can be hammered into thin sheets), and good condutors of heat and electricity. Hope this helped!
What safety device ensures that electricity will flow through it when flowing downhill instead if through people?
Ground wires
Why would you connect wires to a penny?
Answer why does the person who made a circuit a probably connect the wires to a penny
Why is silver not used for electrical wires if it is such a good conductor of electricity?
Silver is not used for electrical wires mainly for two reasons. Silver is too expensive to use and it is a soft metal which is not suitable for electrical wires.
Why does a person wear rubber gloves while handling electric wires?
To prevent being shocked. Rubber is an insulator, and keeps electricity from flowing from the wire to you.
How many wires are there inside electricity cables?
There are three! (i think)
Is polyvinyl chloride an insulator of electricity?
yes, its an insulator. its a type of insulator used for wires, cables, etc
What Is a metal string that brings electricity to our house?
Electricity is brought into our homes along cables of conductive copper wires insulated against shortening by an insulating covering of plastic.
Your Avenger 98 6 dies when close your hood what can that be?
Is the hood hitting some wires or cables (possible Re-routing electricity) as it shuts ?
How does the national grid brings electricity to homes?
By overhead cables, supported on masts, at very high voltage, to reduce the effects of resistance in the wires.
What are the Computer wires and cables and circuits called?
The wires and cables in a computer are often, collectively called "innards" or "guts."
How do you connect a PC to a lan using telephone cables?
You can't using telephone cables. Telephone cables use 4 wires, but none of the wires are twisted, so there will be problems with crosstalk. Also, telephone cables use an incorrect connector (RJ-11) for a NIC card in a PC, which needs RJ-45 connectors.
Why can't we see electricity?
Most of our electricity is made in power stations by machines called generators. Electricity is a kind of energy and it flows into our homes, schools and towns. It happens via the cables buried beneath our feet or wires hanging over our heads.
What is importants of electricity?
The wires and that you have the wires
When electricity flows wires into our home?
Electricity does not flow wires into your home, wires direct the flow of current into your home.
WHAT DOES A CONDUCTOR AND A INSULATOR MEAN?
An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires, A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.
Is it true that an insulator prevents the flow of electricity?
Yes because if that was not true you would get shocks all the time .Also the wires and cables in your homes are all wrapped in plastic (a insulator).
