If a fuse operates when checking equipment in Single Fault Condition as required by

capacitance are made?
& {0 ~4 W  \" f, C3 ZDecision:
Where the fuse link is operator replaceable it should be replaced up to 3 times to enable the

Explanation:
Where operators are instructed to replace a fuse link this should be done for a maximum of 3
times and no hazard as defined in 6.3.2 should arise.
Where the link is not designated as replaceable by the Operator then this should not be done.
