meeting, in Toronto
Question:
If a fuse operates when checking equipment in Single Fault Condition as required by
# L9 M& q; c/ H4 ^Clause 6.3.2, should the fuse be replaced before the measurement of voltage, current and
capacitance are made?
( F% T! A7 _/ ^! L& p9 `Decision:
Where the fuse link is operator replaceable it should be replaced up to 3 times to enable the
