How many gauge numbers in SWG, need to be changed to double the cross-section area of the conductor?
Right Answer is:
Three gauge sizes decreased
SOLUTION
To double the cross-sectional area of a conductor in SWG (Standard Wire Gauge), you need to increase the gauge size by approximately 3 gauge sizes.
In the Standard Wire Gauge (SWG) system:
- Increasing Gauge Numbers: As the gauge numbers increase from 0 to 36, the diameter and circular area of the wire decrease. Higher gauge numbers indicate thinner wire sizes.
- Doubling of Circular Area: The circular area approximately doubles for every three gauge sizes.
- E.g. No. 10 SWG has about twice the cross-sectional area of No. 13 SWG.
