Table 3.1 of GN6 lists the rated short cct capacity for three BS 3036 device designations (S1A, S2A & S4A). But how do you determine the designation of the device?
On a different note, on an eicr, would you give a C2 to a size that was lower than the PEFC or PSCC at the point of use? I've looked in BPG4 and codebreakers but couldn't see anything relating specifically to breaking capacity (sorry if I've missed it).
