cable drawings

[Miley223]

So to me a cable drawing is when you have multiple wires bundles together.

I have this flanged connector. So the house power cable is not long enough to reach our panel. so i have to build a cable that could get me from one panel to another panel on rack.
so i showed photo below. to build this cable i would have to attach the flanged connector to the panel first before i could attach the wires from connect to connector. These wires will be encompassed by a rubber sleeve.

i was going to create a cable drawing to show how this would all be built. i was going to have a note saying connector must be mounted on the panel first to build the harness.

I had someone mention this is a wiring diagram and not a harness since the connector has to be put on the panel first. definitely not the best design i will agree but it was a part we had on hand. would it be cable drawing or a wiring diagram?

to me a cable is a bundle of wires. a wiring diagram could represent a bunch of wires loose and not bundles together.

In addition, are there drawing standards for this. I did find much in the ASME standards on cable or wiring diagrams.

Both.

A wiring diagram for a cable will typically include a wire list that includes the wire routing (from pin X on Connector A to pin Y on Connector B,) which are bundled together, lengths between junctions, and so forth. This is in parallel with the cable drawing that shows any orientation requirements and location of any cable markings. The panel is just a component of the cable and is shown on the cable drawing.

A wiring diagram is part of a cable drawing, as is the wire list which tells which wires are bundled into the cable and which pins or connections the wires are attached to and the parts list, which gives the exact part numbers for all the items that are part of the cable.

So, there is only a cable drawing to describe how to make a cable.

Per NASA:

6 CABLE HARNESS ASSEMBLY DRAWING REQUIREMENTS

A cable assembly drawing is prepared when the design activity has determined that a cable assembly is to be fabricated as a discrete item. This type of assembly drawing depicts an electrical cable assembly of defined length and establishes item identification for that assembly. The assembly consists of wires, shields, cables, or any combination of these, all insulated and with at least one branch properly terminated to connectors, terminal lugs, or other suitable devices (for example heaters, thermostats, pig-tail terminated sensors, jiffy-junctions, bus couplers) and is designed to be installed as a single unit for the interconnection of electrical or electronic equipment. The cable assembly drawing specifies all data required for the fabrication and test of a cable assembly to include potential information for installation at the next higher level. (for example, identification of pigtails)

See https://standards.nasa.gov/sites/default/files/standards/MSFC/Baseline/0/MSFC-STD-3631.pdf

A wiring diagram has no parts list and no individually identified wires and may tell nothing about which functions each wire performs.

There are many types of drawings where a cable may be present.
First, there are many types of cables. For instance, there are power cables -low voltage, medium and high-voltage, control cables in order to transmit the command from one equipment to another, communication cables [ fiber optics] and many other.
The wiring diagram is the exact connection between a terminal of an equipment to the terminal of another equipment. This wire gets a symbol [or a number] and will be included in a cable with other wires.
Each cable will pass through different points like cable trays fragments, manholes, panels and other equipment. Each point is a routing point and has a symbol. A cable routing list describes for each cable the enlisting routing points one after one.
The routing list include also a symbol for cable connection type which is a list of al appurtenances-as flexible connection, reducers, rigid conduit and many others.
There is routing drawing where each routing point is located in an
installation map. There are up to 100 maps where the equipment is located.
A power station of medium size 500-700 MW presents approx. 10000 cables of different types and 100000 up to 500000 routing points.
A group of up to 10 peoples work 4-6 months [minimum] per unit to
do this job.
