[QUOTE="spinlondon, post: 89108, member: 3394"] There are two parameters to consider. The thermal withstand, which is what the k formula is intended to be used for. Then there is the equivelant conductivity, to be determined for if the SWA is to be used as a bonding conductor. The Table used in the link shows the minimum CSA required for the SWA using the K formula. It then shows the actual CSA of the SWA, which in the majority of cases exceeds the minimum. Here is some reading material regarding the use of the SWA as a CPC.
