All, It seems there is a change in 61010-1 regarding the exclusive use to green / yellow color coded parts. In the past these colors were reserved solely for the use of the protective conductor, and protective bonding devices. This is generally true of safety standards based in or harminozed to 60664-1.
Now I find in the third edition of 61010-1 has a provision for use of green / yellow on "potential equalization" and "functional earthing" in section 6.9.3 c) & d). In addition Table 1, symbol #8 Equipotentiality (IEC 60417 - 5021) is removed from use. I always understood protective bonding is a mandatory safety connection and functional or equipotential ground are not and should not be used for electrical safety hazard protection. Can someone please explain the committee's rationale behind this? I really feel this waters down the importance of protective grounding and protective bonding; especially when working with high powered or high voltage equipment. thanks -doug - ---------------------------------------------------------------- This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
