1. Bs3871 normally 6Ka

2. Yes 3036

3. Could be bs60947-3

4. On a PIR pre 17th its EEBADS

1. More than likely BS 3871's, there will be an 'M' rating on them somewhere.
2. Correct
3. The fuses in the switchfuse will more than likely be BS 88's, the switch itself, BS 5419 depending on age. Ottermill is ancient stuff now so I would have thought 5419.
4. The method of protection when that installation was fisrt installed would be EEBADS.
