What was found

GALLEY C BEV MAKER NR5 TEA POT RETURNED TO STOWAGE, BREW HANDLE MOVED DOWN TO POT. A FLASH OF WHITE SPARK WAS SEEN FROM BEV MAKER. BEV MAKER SWITCHED OFF. A VISUAL INSP IN THE WORKSHOP FOUND THAT THE SWITCH ACTUATOR PLATE ATTACHED TO THE BREW HANDLE HAD RUBBED AT THE SWITCH CABLES EXPOSING THE INNER CORE, SUBSEQUENTLY CAUSING A SHORT TO GROUND. FOLLOWING AN INSP OF ANOTHER 64751-1, IT WAS NOTED THAT THE OTHER UNIT WAS FITTED WITH A P-CLIP TO RETAIN THE CABLE SO THAT THE POSSIBILITY OF CONTACT WITH MOVING PARTS IS MINIMIZED. HOWEVER, THE SUBJECT UNIT DOES NOT HAVE A P-CLIP FITTED OR HAVE A HOLE PERMITTING FITMENT OF A P-CLIP, SUGGESTING THAT THERE ARE DIFFERING STANDARDS OF 64751-1 UNITS. (K)
