The PROTECTIVE EARTHING CONDUCTORS should be terminated at that point. A
recognized or certified closed loop connector (ring terminal) should be used and secured
to the frame with a lock washer using a bolt or stud. The connector should be properly
sized to be suitable for the bolt or stud, the locking washer, the rating for the
conducting wire used, and the considered rating of the breaker. The intent is to ensure
the frame is electrically bonded to the PROTECTIVE EARTHING CONDUCTORS. The
hole that the bolt or stud goes into where the terminal conductor and the lock washer
contact should be free of any non-conductive material to allow for metal to metal
contact. All PROTECTIVE EARTHING CONDUCTORS should terminate at this main
protective earthing terminal or at points marked with . (R010)
