In a factory the harness is usually the last item on the critical path. Pre-forming the looms moves that work off a step ladder in a switchroom and onto a bench where the conductor can be stripped, ferruled, measured and rung out without anyone reaching over live equipment.
Two details separate a loom that works from one that wastes an engineer’s afternoon. The first is the ferrule: every stranded conductor landing in a cage or spring terminal should have one, crimped with the correct profile. The second is identification, printed and keyed to the schematic. Neither is expensive and both are routinely skipped.
The group splits into two kinds of work. A panel loom is static: it is built to a drawing, measured against a mounting plate, and its wire is chosen on voltage, temperature and how it behaves in a terminal — UL1015 or UL1007 for a North American panel, H05V-K or H07V-K where the machine is sold in Europe and the internal wiring has to satisfy the harmonised standard. A machine loom on a moving axis is a different problem, and it is built on the continuous-flex shielded multi-conductor lines: UL2464, UL2587, UL20276, UL20327 and the wider drag-chain family.
Ferrules are chosen to the terminal rather than to the wire. A DIN 46228 part with the correct sleeve length is what makes the joint, and the crimp tool has to match the ferrule profile — a generic plier that closes the barrel without forming it is the origin of most loose-conductor faults found in a finished panel. Where the conductor is fine-stranded for flex, the same rule applies with a longer ferrule to spread the load.
A loom leaves the shop with a from-to schedule, the ferrule map, a continuity record for every position, and split points chosen so that the assembly passes through the door and around the machine frame. Circuit identification is printed on sleeves rather than hand-marked, because a hand-marked core is unreadable after two years in a switchroom, and the same identification is repeated in the drawing package returned with the part.

Industrial & Automation harness questions
What buyers ask before they send a drawing for this group.
When should a conductor be ferruled instead of crimped into a ring terminal?
A ferrule is for a conductor that lands in a clamp, cage or spring terminal; a ring or fork terminal is for a stud. The two are not interchangeable, and the failure mode when they are confused is a joint that looks tight and loosens under thermal cycling. In a mixed panel both are used on the same core, driven from the from-to list.
Which harness lines suit a moving machine axis?
The continuous-flex shielded multi-conductor lines — UL2464, UL2587, UL20276, UL20327 and the rest of the drag-chain family — because the flex rating, not the conductor size, decides the life of the assembly in a chain. The bend radius imposed by the chain is the number that matters, and a standard PVC hook-up wire will pass a continuity check on day one and fail at the connector within a few hundred thousand cycles.
Can a control panel loom be delivered pre-formed and pre-labelled?
Yes, and it is the usual way for repeat builds. The loom is formed on a board to the panel layout, the branches are cut to the measured lengths, and every core carries a printed sleeve before the assembly is bundled and bagged. On site it is laid into the duct and terminated, which removes the measuring and marking step from the electrician’s task.
