2. Neher–McGrath method - Wikipedia

   en.wikipedia.org/wiki/Neher–McGrath_method

   By estimating the temperature of the cables, the safe long-term current-carrying capacity of the cables can be calculated. J. H. Neher and M. H. McGrath were two electrical engineers who wrote a paper in 1957 about how to calculate the capacity of current (ampacity) of cables. [ 1 ]

3. IEC 60228 - Wikipedia

   en.wikipedia.org/wiki/IEC_60228

   Comparison of SWG (red), AWG (blue) and IEC 60228 (black) wire gauge sizes from 0.03 to 200 mm² to scale on a 1 mm grid – in the SVG file, hover over a size to highlight it. In engineering applications, it is often most convenient to describe a wire in terms of its cross-section area, rather than its diameter, because the cross section is directly proportional to its strength and weight ...

4. Ampacity - Wikipedia

   en.wikipedia.org/wiki/Ampacity

   Conductors installed so that air can freely move over them can be rated to carry more current than conductors run inside a conduit or buried underground. High ambient temperature may reduce the current rating of a conductor. Cables run in wet or oily locations may carry a lower temperature rating than in a dry installation. A lower rating will ...

5. Extra-low voltage - Wikipedia

   en.wikipedia.org/wiki/Extra-low_voltage

   Cable sizing must therefore consider maximum demand, voltage drop over the cable, and current-carrying capacity. Voltage drop is usually the main factor considered, but current-carrying capacity is as important when considering short, high-current runs such as between a battery bank and inverter.

6. Power cable - Wikipedia

   en.wikipedia.org/wiki/Power_cable

   Power cables use stranded copper or aluminum conductors, although small power cables may use solid conductors in sizes of up to 1/0. (For a detailed discussion on copper cables, see: Copper wire and cable.). The cable may include uninsulated conductors used for the circuit neutral or for ground (earth) connection.

7. SY control cable - Wikipedia

   en.wikipedia.org/wiki/SY_control_cable

   An SY control cable is a flexible instrumentation electrical cable designed for measuring, control or regulation in the field of process automation. [1] It is a flexible multicore cable , with (class 5) [ which? ] copper conductors and a galvanised steel wire braid (GSWB) for mechanical protection.
