Does a 4corex630 sq mm cable carry the same current as a single core 630 sq mm cable?

4-core 630 mm-sq cable sounds like 4 cores each of 630 mm-sq as used on 400 kV power lines, in which case it carries 4 times the current.

What is current value after derating factor considered?
Once derating factor is considered the size of cable for perticular electrical load increased by the multipling factor.i,e if 2.5MM2 cable is capable to carry 14amp. of current in general then with 40% of derating fator it can carry only 8.4amp.
Why we go for bus bar riser system instead of cables?
It is done to carry more current at rated power & to reduce the power loss as compared to cable since a bus-bar has more area compared to cable so resistance is less & hence losses are reduced.

Why the cable size is expressed in Sqmm not in diameter regardless of single or stranded conductor?
The cross-sectional area is one of the factors that determines how much current a conductor can carry -this is regardless of the shape of that conductor's cross section (many conductors are not circular). So the diameter is of not much interest.
How much do submarine cables cost?
A. The cost of a submarine cable depends on its length, how many fibres it contains and the number of channels it is intended to carry. To give you an idea, a single transatlantic cable would cost around $500m ( £307,443,000). We can carry out feasibility studies and costings for any systems you may be considering.
What is difference between cable tray and cable trunks?
Cable tray is a system of wiring in a building in which insulated electrical wires are used to distribute power and communication to various access points. Cable trunks are power supply lines that are used to distribute power and communication services to large areas such as industrialized cities.
Does coaxial cable carry a current?
Yes, this is how the data is transmitted.
How much current does 20 AWG cable carry?
30 Amps
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.
Will a 5 amp device work with a .5 amp power cable?
Yes, the larger cable can carry more load (current) than the other cable.
Current carrying capacity of cable?
what is the current carrying capasity of 16mm cable
What cable companies carry Fox FX?
Most Cable TV companies carry the FX channel. FX may be in a different tier if you cannot find it with your current cable lineup. Satellite television also carries FX.
How much current can 5kv cable carry?
It depends on its cross-sectional area, its construction, and how it is laid.
How much current carry 1 sq mm copper cable?
2 A
What part of a circuit is the wire cable or switch?
Wire is the transition material used to carry the electric current; the switch is the controller of that current.
Will a 12v 2 amp device work with 12v 5 amp power cable?
Yes, the larger cable can carry more load (current) than the other cable.

How to measure Electrical UG power cable sizes?
All wire is sized by the amount of current that they can safely carry.
