Refer to table 4f2a notes 2 3 of bs 7671.
2 these ratings are not applicable to cables wound on reeling drums or covered over or coiled up.
Reference method f in free air or on a perforated cable tray etc horizontal or vertical etc reference method g in free air touching.
American wire gauge size calculator and chart.
1 the tabulated current ratings are for cables in free air but may also be used for cables resting on a surface.

It is based on cable type insulation type and the cable installation method.
Today we are here with another comprehensive copper and aluminum wire size calculator as we have discussed in detail the topic of how to calculate the proper wire size for electrical wiring.
Multi conductor cables except for house or handheld units rubber.
Note w m wire gauge us steel wire gauge and music wire gauge are different systems.
Mono conductors rubber insulated pvc insulated heat resistant.
On or at surfaces.
Aluminum and flexible cables are not supported yet.
Awg general rules of thumb for every 6 gauge decrease the wire diameter doubles and for every 3 gauge decrease the cross sectional area doubles.
The cable sizing calculator considers solid or stranded copper conductors only.
Flexible cables are used for appliances because appliances usually get moved around a lot and the inflexibility of a fixed cable either 1 5mm or 2 5mm would soon crack the cable causing faults and potentially the risk of shock and injury.
Now you can take the advantage of this calculator to do this job j you can also check the classical wire cable size calculator in awg calculating wire cable size formula for single phase circuits.
