Guest Posted October 22, 2005 Posted October 22, 2005 I have seen a lot of installs by the others using the white of 4 core etc as the earth sleeving! Or just a piece of 8 core on a plug top.......
Truss and France Posted October 22, 2005 Posted October 22, 2005 Norman Im not bothered whether you disagree or agree, ive always done it this way and everyone ive worked with has done it this way, never been pulled up for doing this way, mind you we are down south which might make difference. Dont know where your from, but I do know things are done different up north and im not saying its right or wrong because 'am I bothered' no! Keep on smiling. Kevin
Guest Posted October 22, 2005 Posted October 22, 2005 That's him told then. For the record, the main thing should be that the supply is safely connected. I would prefer to use flex in some situations but I'd rather see a tidily connected piece of t+e than anything else bodged in in some sort of random fashion.
Guest Posted October 22, 2005 Posted October 22, 2005 Alway tin the ends of the flex aswell. I personally wouldn't tin the flex as over time the soft solder will deform with the gentle 50hz hum that it has running through it. This will cause a bad connection eventually and can cause other problems. In practice, I'm not sure I've actually seen this happen but then I haven't seen many long term tinned multistrand cables under screws. If you want to do a decent job of it use some crimped ferrules.
norman Posted October 22, 2005 Posted October 22, 2005 That's him told then. Nothing is foolproof to a sufficiently talented fool.
newbec Posted October 23, 2005 Posted October 23, 2005 I personally wouldn't tin the flex agree as over time the soft solder will deform with the gentle 50hz hum that it has running through it. I work with and upgrade a lot of gas detection panels, some of which the terminals have not been touched for 20+years. All the internal panel wiring terminations are always stranded tinned (soldered) conductors. Most of which at the time of removal are, and always have been, switching 50hz 220-250V loads. I have never been called to a system where the above quote has been the cause so therefore: In practice, I'm not sure I've actually seen this happen and I doubt you ever will! By the way, to agree with the last of your statements, all replacement panels that leave our workshop now have conductors terminated utilising bootlace ferrules because: 1) Labour saving 2) Stops ident numbers from falling off!!!

Rich Posted October 23, 2005 Posted October 23, 2005 tinning multi strand cables for terminal blocks can cause the cable to snap as the screw crushes the cable it cuts through the strands, non tinned cable the screw just crushes the strands and they are able to spread the load. Crimp on pins would be better.
whistle Posted October 23, 2005 Posted October 23, 2005 ??? 17 years in the game never seen one job yet with tinned flex ???
daiashthomas Posted December 8, 2005 Posted December 8, 2005 sod wiring a panel that neatly i like to make mine neat but not use single cores to loom everything for fault finding etc.. as stated by other members. also always use flex regardless of entry point and always use gromets or stuffing gland. and as far as tinning the ends of flex........ pah... as if one thing that does p*** me off is when u go to a job and all the Aux 12v + and - cables are twisted together and rammed into the pcb terminals Trade Member
