"Two by two, hands or blue" - River (Firefly) The other Brian -----Original Message----- From: John Allen [mailto:john_e_al...@blueyonder.co.uk] Sent: Friday, January 16, 2015 2:48 PM To: EMC-PSTC@LISTSERV.IEEE.ORG Subject: Re: [PSES] safety distances in DC/DC Rich That seems like a classic case of the IEC "management" not clearly "laying down the law" on the need for the various TCs to ensure that they operate in a consistent manner - maybe these terms should be defined clearly in IEC 60050 and for the various TCs to use those definitions very consistently, and without deviation? (or have I just opened another can of worms that nobody wants to get to grips with?) John Allen W.

There are many definitions of SELV and PELV. It would seem that every TC has its own definitions. Just 5 for FELV and they are consistent. Also, check out ELV (which makes the FELV inconsistent).
