UL 1569 Thin-Wall PVC Wire for Compact Electronic Equipment
UL AWM Style 1569 is a single conductor with extruded PVC insulation, rated 300 Vac with Horizontal Flame, in 80°C, 90°C or 105°C temperature ratings. The Style conductor range is 30 AWG through 2 AWG, solid or stranded.
This page covers the 30–10 AWG group, where the Style specifies 15 mils minimum average insulation with 13 mils minimum at any point, for fixed internal wiring in compact electronic equipment — designs where the buyer controls maximum finished wire diameter or routing clearance.
Compact is a dimensional design context, not a UL performance designation. The official Use is internal wiring of appliances or electronic equipment where not subjected to movement or mechanical damage, and this page works within the electronic-equipment branch with that condition attached.

This page focuses specifically on the 30–10 AWG / 15 mil base-insulation group for fixed internal wiring in compact electronic equipment.
A 15 Mil Wall Is Not a Finished Diameter
This is the most useful thing to settle on a page written for dimension-controlled designs.
The Style states minimum insulation-wall requirements. It does not define one universal finished outside diameter, and a finished OD cannot be obtained by taking the wall figure alone. What sits between the two is the conductor: its size, whether it is solid or stranded, and its detailed geometry, together with the actual insulation extrusion and whether the optional PVC covering is included.
So the verified statement available here is that the 30–10 AWG group carries a 15 mil minimum-average base insulation requirement with 13 mils minimum at any point. The statement not available here is any finished diameter. No guaranteed slim profile, minimum finished diameter, ultra-small OD, smallest available wire or guaranteed space saving is claimed, and none is calculated from the wall thickness.
A buyer working to a strict internal clearance therefore needs to specify a maximum OD and tolerance rather than selecting on insulation wall. Those are different specifications answering different questions.
Dimensional Information to Supply
For a compact electronic design, the enquiry is far easier to answer when it carries the dimensional constraints explicitly:
- Required conductor size
- Maximum finished OD
- OD tolerance
- Available routing clearance
- Terminal or connector cavity constraint, where applicable
- Whether the optional PVC covering is required
No dimensional value is invented on this page. Where the drawing controls a dimension, it is checked against the ordered construction rather than derived from Style-level data.
Thin-Wall Applies to 30–10 AWG
Style 1569 has two base-insulation groups. From 30 AWG through 10 AWG the requirement is 15 mils minimum average with 13 mils minimum at any point. From 9 AWG through 2 AWG it is 30 mils minimum average with 27 mils minimum at any point.
Thin-wall on this page refers to the first group. It is not accurate to say Style 1569 is universally a thin-wall Style, that all Style 1569 wire has a 15 mil wall, or that all sizes from 30 AWG to 2 AWG share the same insulation thickness. The Style does extend through 2 AWG, on the thicker requirement, and thin-wall is not the formal UL title of the Style.
Compact Does Not Mean Automatically Suitable
A product being compact does not by itself make Style 1569 the right choice for a lead inside it.
The evaluation still has to cover the required AWG, the temperature at the wire position, the voltage requirement, the actual finished OD, the internal clearance, the conductor construction, whether the optional covering is needed, the mechanical protection available, and whether the wire remains fixed in service. Style 1569 is not described here as ideal for every compact device, as automatically solving space problems, or as guaranteeing space savings.
Compact equipment in particular often contains moving mechanisms in close proximity to fixed wiring, which makes the next two sections directly relevant rather than formal.
Movement Restriction
The Use excludes wiring subjected to movement. That wording is broader than a repeated-flexing restriction, and being inside the equipment does not satisfy it.
Style 1569 is not positioned here for continuous flexing, moving hinges, sliding mechanisms, robotic motion, drag chains, repeated-motion cable loops or unprotected moving assemblies. The intended context is fixed, protected internal wiring. Where one section of a run crosses into a moving position, that section requires separate evaluation even if the remainder is stationary.
Mechanical-Damage Restriction
The Use also excludes exposure to mechanical damage, and a thin wall does not offset this.
No abrasion resistance, cut-through resistance, mechanical reinforcement or impact protection is claimed for the construction, because the Style data establishes none. Where the installation exposes the wire to mechanical damage — a sheet-metal edge, a pinch point on assembly, a service access path — the buyer reconsiders the construction or the protection method rather than relying on the insulation.
Fixed Internal Electronic-Equipment Contexts
The practical contexts for this page are protected internal electronic assemblies, fixed component-to-component leads, enclosed electronic modules, electronic control sections, electronic subassemblies with limited internal clearance, and drawing-controlled internal wire paths.
These are examples falling under the electronic-equipment branch of the official Use, provided the wire is not subjected to movement or mechanical damage. They are not separate UL-approved application categories.
The Use does not extend to building wiring, field wiring, branch circuits, tray, conduit, raceway, external equipment power leads, portable cord, general industrial wiring or machine field wiring.
Temperature Rating
UL AWM Style 1569 includes 80°C, 90°C and 105°C rating possibilities, with the required rating confirmed for the ordered construction.
These are alternatives rather than a combined rating. Nothing here states that all Style 1569 is 105°C, that 105°C is standard, or that a single wire carries 80, 90 and 105°C simultaneously.
300 Vac and the Optional Peak Tag
The normal Style voltage rating is 300 Vac, used precisely here. The product is not described as 600V wire, 600 Vac wire or 300/600V wire.
The Style may separately carry a tag indicating “600 Volts Peak for Electronic Use Only.” That is not the normal continuous voltage rating:
Normal rating: 300 Vac.
Optional tag: 600 Volts Peak for Electronic Use Only.
It is not converted here into 600 Vac, 600V continuous, ordinary 600V electronic wire or 300/600V, and where a design references it, the ordered construction is what confirms whether it applies.
The Optional PVC Covering
Style 1569 permits an optional extruded PVC covering at 9 mils minimum average with 8 mils minimum at any point.
Not every construction contains it, and it is not described here as a mandatory jacket, as double insulation, or as providing mechanical protection, abrasion protection or extra flame protection. It is worth noting on a dimension-controlled page that including the covering changes the finished dimensions — which is exactly why whether it is required belongs in the enquiry as an RFQ confirmation field.
Conductor Requirements
Style 1569 establishes the 30 AWG–2 AWG range and the solid or stranded form, and nothing else about the conductor.
Copper, tinned copper, bare copper, silver-plated copper and nickel-plated copper are none of them established at Style level, and no strand count, strand diameter, lay length, conductor resistance or ampacity is stated here. Specific conductor material, plating and stranding are confirmed from the ordered construction, verified SKU documentation or the customer specification — and since conductor construction directly affects finished dimensions, it is a relevant field on this page rather than a formality.
What Style 1569 Does Not Define
- Conductor material and conductor plating
- Strand count and strand diameter
- Finished OD and OD tolerance
- Conductor resistance and ampacity
- Bend radius and flex life
- Colour
- Terminal, connector and cut length
- MOQ, stock and lead time
None of these is invented here; each requires the buyer’s specification, verified SKU documentation or commercial confirmation.
Common Procurement Errors
- 15 mil insulation assumed for all sizes. It applies to 30–10 AWG only.
- 9–2 AWG treated as part of the 15 mil thin-wall group. That group requires 30 mil average.
- The Style assumed to guarantee a specific finished OD. It specifies insulation wall, not diameter.
- Wire selected from insulation wall alone without checking conductor construction.
- Every Style 1569 wire assumed to be 105°C. The Style permits 80, 90 or 105°C.
- 600 Volts Peak treated as a normal 600 Vac rating. The rating is 300 Vac.
- Stranded tinned copper assumed. Conductor material is not set at Style level.
- Used in a moving mechanism. The Use excludes movement.
- Optional PVC covering assumed always present. It also changes finished dimensions.
- “Compact” used in place of an actual maximum-OD specification. The word cannot be checked against a construction.

Substitution
Different AWM Styles have different ratings, construction requirements, Uses, temperature limits, voltage ratings and insulation structures. No Style is presented here as substitutable for Style 1569 merely because it has a different profile.
Any alternative is evaluated against the customer’s actual equipment specification, including the dimensional constraints and the movement and mechanical-damage conditions that apply to this Style’s Use.
UL Marking and Documentation
Material is supplied as UL-recognized component wire where supplied under qualified manufacturing scope, and UL marking is applied according to the confirmed ordered construction. The Style-level marking designation is General.
CSA AWM, FT1, VW-1 and dual UL / CSA certification are not claimed here; any additional certification depends on the ordered construction. Applicable RoHS / REACH documentation can be confirmed according to the ordered construction.
Flame Classification
The verified Style-level designation is Horizontal Flame. VW-1 and FT1 are separate classifications and are not claimed here; Horizontal Flame is not converted into either. Any separately confirmed vertical-flame requirement remains order-specific.
