Determining device designation of rewirable fuses

Farmboy
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).

    From the same era, I have been told by the older sweats that the traditional cotton twill flat cap may used to hold the fuse on suspect circuits to act as a simple arc mitten and also with a beating motion as basic emergency extinguisher for small fires.

    This is not really advice that should be written into any modern risk assessment - it may lead to  comment at the review stage.
