The Adiabatic Equation for calculating the cpc (circuit protective conductor) and earth minimum csa sizes for earthing conductors.
Adiabatic Equation Calculator Formula
t = Disconnection time (seconds)
k = Conductor k value (From BS 7671 tables)
la = Fault current (PEFC in Amps)
I² = la x la
Values of K obtained from the tables within BS 7671
- Table 54.2 : Conductor not incorporated in a cable and not bunched with cables.
- Table 54.3 : Conductor incorporated in a cable or bunched with cables.
- Table 54.4 : Sheath or armour of a cable.
- Table 54.5 : Steel conduit or trunking.
Disconnection times (t) are obtained from the maximum operating time/current characteristics tables within BS 7671
- Fig 3A2 (a,b) : BS 3036 semi-enclosed fuse
- Fig 3A3 : (a,b) : BS 88-2.2
- Fig 3A4 : BS EN 60898 / 61009-1 MCB/RCBO type B
- Fig 3A5 : BS EN 60898 / 61009-1 MCB/RCBO type C
