To answer this question the voltage is needed.
A device designed to permit the entry of a cable into an electrical equipment and which provides sealing and retension. Cable well tightened with supporting of cable holding material into an electrical equipment or panels.
To answer this question the size of the cable or the amperage of the load is needed to calculate the correct wire size and connectors to fit the cable.
Armored electrical cable contains insulated electrical service wires protected by a flexible steel covering. Metallic Conduit is a tube or pipe though which we lay electrical cable.(Most commonly lighting cables).
The current-carrying capacity of a cable depends on a number of things in addition to its cross-sectional area; these include the type of conductor, number of cores, type of insulation, whether or not it is armoured, method of installation, etc. Accordingly, to determine its current-carrying capacity, you will need to refer to your national electrical code. For example, in the UK, BS 7671:2008 Requirements for Electrical Installations contains tables for all standard cable types, specifying current-carrying capacity, voltage drops, etc.
The cable size is : 4*25 mm2
Electricians will use their electrical code book to fine these values.See related links below
Wire size becomes an electrical hazard when it is under rated for the amount of current (Amps or I) it has to carry.Current is the flow of electrons in a circuit. If the current is too large for the cable, the cable will be subject to heating, which is a possible fire hazard.
what should be the distance between instrument cable and electrical cable
Most industrialised countries manufacture electrical cable.

Cable
Copper cable with PVC insulation
Wire is sized by the amount of amperage the device to be connected draws. Without this data the question can not be answered.
