Allowable ampacities for not more that 3 copper conductors in a cable based on an ambient temperature of 30 degrees C.
A #1 copper conductor with an insulation factor of 75 or 90 degrees C is rated at 130 and 140 amps respectively.

Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
What wire size should you use for a 80 amp electric box?
A #14 copper conductor is rated at 15 amps.
Why is a cable on a plug made from copper?
Copper is a very conductive metal and also ductile.
Why copper cable better than aluminium cable?
Copper cable doesn't conduct as well as Aluminum , but for most applications, Copper doesn't heat up as quickly as Aluminum, and is stronger in tensile strength. Also when using Aluminum cable you need to use an oxide to help conduct as Aluminum will work loose from locks in time.
What is the standard length of power supply cords?
That depends on waht the instrument is and is being used for and what is being carried in the electrical cable. If the electrical cable is carrying DC, there is not much to worry about unless the current is very high. AC/modulated current in the electrical current will induce currents in the instrument cable but how great the problem will be depends on current and frequency. Normally, a few inches separation would be enough. If there is likely to be a significant probelm it would be normal to used screened cable for one or both.
What is the actual loss of voltage in 100 meter length of cable?
It depends on the material of the cable (aluminum or copper) and the gauge of the cable. (Thickness). And on the current you intend it to carry.
What is the maximum current capacity of 4 sq mm copper wire?
I can say it is 29 Amps.But again it depends on the cable length.The more the cable length is the less the current carrying capacity will be.
What ia Standard of dc loop resistance of copper cable?
It depends on the length of th cable and the diameter of the copper cable used.
What size cable for 50 amps 3 phase for 650 meters length?
70mm 4core copper cable
What is the current rating of 25mm 4-core armoured cable?
You have to be specific. whether the conductor is aluminum or copper. Current carrying capacity will be different for these two types. Copper cable can take more load than aluminum cable for same diameter.
10 What is the maximum length of a serial cable?
The current maximum length for a serial cable is around 50 meters. Different cables have length limits with the maximum varying.
What will happens to current when cable length increases?
With a constant voltage and increase in wire length will increase the end to end resistance and therefore the current will decrease.
How much current carry 1 sq mm copper cable?
2 A
Why are copper wires used in as connecting wires?
The copper wires used connect. Because conductivity of Cooper higher than aluminium but price of Cooper higher than aluminum. If compare between copper and aluminium cable can see at the same current rate diameter of aluminium cable is larger than copper cable.
What is the maximum length of an 80- wire PATA cable?
3216514635165165 3216514635165165
4 sq mm copper cable current carrying capacity?
25 amps, 6000 watts
Why aluminium cable cost less than copper cable?
copper cost more to mine then aluminum so aluminum will cost less then copper cable.
