Background:
  \- v* K* G) T' K. ?) Z* ?3 k4 LThe combined appliance inlet / fuse-holder / voltage selector illustrated on page 2 has certification to IEC 60320 and is being used in audio equipment in the scope of IEC 60065. As can be seen from the photographs, the fuse carrier cannot be removed before first pulling out the appliance coupler. However, when the fuse carrier is removed there is direct access to the live fuse clip using the standard finger.
Question:
Question 1- Should the tests for access to live parts be conducted assuming that the appliance coupler could subsequently be re-inserted?
(c/f “Inadvertent reactivation” of safety interlock – clause 14.7)
Question 2- If the answer to question 1 is “yes”, how do we determine whether or not the
fuse carrier can be removed BY HAND?
