While still warm from the above tests an alternating voltage of 200 from the lighting mains shall be applied through a light fuse for 10 minutes without breakdown, between the armature and field windings and the motor xxxxxxx casing. TEST 5. MECHANICAL EXAMINATION. The bearings should be examined to ensure that there is no undue slackness and the Bijur drive should move freely along the screw.
