I wish to state that I agree with the use of the FI (Further Investigation required) code for apparent deficiencies with the DNO's equipment. In principle if fused neutrals were suspected (without getting in to whether this was a reasonable belief or otherwise) then the DNO are needed to verify this, and so further investigation without delay is required. It is also clear that this must result in an Unsatisfactory report.
