0 g# u7 ~. v/ y) ]22.35 For constructions other than those of class III, handles, levers and knobs that are held or actuated in normal use shall not become live in the event of a failure of basic insulation. If these handles, levers and knobs are of metal and if their shafts or fixings are likely to become live in the event of a failure of basic insulation, they shall be adequately covered by insulating material or their accessible parts shall be separated from their shafts or fixings by supplementary insulation.9 p( N _$ U5 }

根据以上要求,除III类产品外,如果其handles, levers and knobs是金属的,则该handles, levers and knobs 必须与live part之间满足加强绝缘或者双重绝缘(如果它与live part之间只满足basic,则其accessible的地方必须要covered by insulating material),即使这个金属的handles, levers and knobs 接地了。对于这点CTL还专门出个决议,见附件。% n( @; F$ o8 s
