which way should cable numbers be fitted?

[billyfender]

Anyone know which way round cable numbers should be fitted onto a cable. That is, should it read away from the end or towards the end. I was always taught to put the numbers on backwards so the number was always be read away from the end of the cable but we've had some panels in recently which have the numbers reading towards the end of the cable.

Which came first the chicken or the egg?

Considering the terminals they usually go into can be of different orientation then you should fit them so they are easily read in their terminated position .... if you did as you were taught consider a panel din mount connector the numbering should read the same way going in the top as it does coming out of the bottom but because the cables approach the opposite way the numbers will need to be fitted in 2 different directions.

Im not aware personally of any specific requirement its just a case of each to their own and limit confusion or head twisting.

going back to the days when coloured rings without numbers printed on them. It was read from the termination.

i was always taught, back in the old days that the numbers read from the terminal end.

I was too.

Numbering away from the terminal was our early company standard. When we started to use larger MCC’s we changed.

Vertical termination rails the characters to be orientated to read correct. Horizontal rails orientated to be read from the right.

Get a terminal chamber with 5000+ terminals, the last thing you need is for the ferules to be upside down.

it was done this way for a reason. you has to slip the numbers on in reverse order so that it was beyond the capabilities of plumbers.

come on guys this is a basic english question.

we read from left to right so thats the way it should be read from the terminals.

obviously is varies depending on where the terminal's are.


why do you think gas fitters don't like being called plumbers, because they managed to get there head around the fact gas bottles tighten opposite way to water

I've always stuck with reading from the ferrule end from the days of building machines for Ford as it was in their spec's. I remember one contractor having to spend days redoing a panel full of terminals!

Yep I did a ford apprenticeship and that's how it was taught,when I arrived at the papermill I was told it should be done the other way,although neither of us could argue who was right!!!!

i was looking at a load of Zener barriers in a panel offshore and they were numbered

51/2348/rig 2 (terminal block) rig2/2348/51

which I thought was very odd and confusing????

100 % read from the terminal end,thus from your stripped cable end,the number should read back up the cable.So for say 456,you would slide the 6 on first,then the 5,then the 4,then put the cable in the terminal,this way any future engineer will be able to understand your numbering.This doesnt apply to German or Italian machines as they never bother numbering cables in any case! LOLS!

stop buying cheap numbers then. ours have a line on to show difference between 6 and 9 etc.

and colour coded, how much clearer can you be?

I always use Partex chevron cut colour coded markers.

Always read away from the terminal/gland. Although where I currently work, if your looking at the left hand side of the terminal, the ident reads away from the terminal but it is upside down!

 

[telectrix]

i can read upside down. do it standing on my head.

 

[bcm_spark]

Yes but the safety boys frown upon this method of inspection

It doesn't matter...

[telectrix]

well, australians do it all the time, so it can't be hard.

Many of our panels would interconnect to other panels.

K5/F3/103 would equate to
K5 = kiln 5
F3 = a starter draw in row 6, 3[SUP]rd[/SUP] from the top
103 the wire number for that particular starter

The product handling plant had inputs from all over the place. About the only way to isolate everything to that panel would be open the 11KV breakers. (You wouldn’t be popular!).
Every starter had the same wiring layout no matter where it was.

Having to read upside down was thrown out early on
