Ike Posted February 8, 2004 Share Posted February 8, 2004 Not sure if this is the right place but anyway... Just contemplating making up some new control cables for chain hoists using the yellow four pin cee forms and was wondering if there was any specific colour codes to use. Im looking to use some 5 core TRS we have left over but am equally unsure what to do with the spare conductor, should I cut it off with the sheath or use two conductors for the protective or common connection? Any advice will be much appreciated. Link to comment Share on other sites More sharing options...
robloxley Posted February 9, 2004 Share Posted February 9, 2004 This PCM Lodestar page has some useful wiring info. As for what cabling to use, I'm not sure what the IEE Regs say on using mains cable for control purposes, except that you really shouldn't use the earth for anything other than earth. Maybe someone else has the relevant bit in the front of their mind? Link to comment Share on other sites More sharing options...
ianl Posted February 9, 2004 Share Posted February 9, 2004 given that the control is of mains voltage, mains cable is fine ( part of the discusion over use of ceeform was because they were not meant for control voltages) the control 4 pin connector has live, 2 switched lives and an earth, asuming you have standard 5 core flex ( brown , 2 black , blue, green/yellow) then the regulations would indicate use of brown for live and the 2 black wires for switch live. the regulations prohibit use of anything other than green/yellow for earth ( or using G/Y for anything else) so dont use the blue wire, best to cut it off Link to comment Share on other sites More sharing options...

Andrew C Posted February 9, 2004 Share Posted February 9, 2004 Strictly, the yellow CEE form connectors are for 110V although they may be physically capable of 240V. The colour, and keying, is to prevent inadvertent interconnection. Do your hoists use low voltage for control? Link to comment Share on other sites More sharing options...
Ike Posted February 10, 2004 Author Share Posted February 10, 2004 It is low voltage control and im pretty sure its 110V ~ anyway I will check on wednesday as I have tomorrow off :D Link to comment Share on other sites More sharing options...
