Hi,

First, I am not familiar with the notation 1/C... 2/C.. 3/C... etc..

From what I've read I understand that:

1/C Means "a single cable with only one conductor (core)"
2/C Means "a single cable with two conductors (cores) inside a common outer jacket"
3/C Means "A single cable with three conductors (cores) inside a common outer jacket"
4/C Means "A single cable with four conductors (cores) inside a common outer jacket"

My question:
How should I notate a multi-core cable that have a protective earth conductor inside the common jacket?

3/C+PE?
3/C w/PE?
3/C w/GND?
Etc

Thanks!

This is location/region specific. Who will be trying to interpret? You can do whatever you want if you simply include a legend to explain it.
 
Hi dpc,

I imagined that it varies from country to country, but I would like to use the most accepted acronym worldwide. Anyway, I'm adding references

Thanks.

If you specify a cable type that is covered.
AC cable
ACWU cable
TECK cable'
And a lot of other cable types include a PE condustor.
For instance Teck is available in layups from 1 core to dozens of cores.
If it is TECK it will have an earth conductor in addition to the cores.
eg 3c TECK = 3 conductors plus an grounding conductor.

Hi Bill,

What is the origin of that designation? Are manufacturers trade-names or are they specified in a standard? Here in Argentina, we don't use that names.

I just want a generic notation for multi-cores cables included a PE conductor

Thanks,

Those are cable types as designated in our codes.
Some of the designations are based on the cable construction, some are not;
AC90 Armoured Cable, 90 degrees
ACWU90 Armoured Cable Wet Underground 90 degrees
NMD Non Metallic Dry
NMW Non Metallic Wet
NMWU Non Metalliv Wet Underground
Teck Teck cable is a type of low voltage armoured cable named for the location where it was first developed and used, Teck Township, now known as Kirkland Lake, Ontario.
On the other hand3c + 1 works also. Include the note.
