16 AWG Sits at the Upper Boundary of the UL 3122 Range
UL AWM Style 3122 covers a conductor range of 26 AWG through 16 AWG — and 16 AWG is the largest conductor size the Style permits. That boundary position matters for BOM verification: a buyer approving a “UL 3122 16 AWG” line item is specifying the upper edge of what this Style covers, not a mid-range or arbitrary gauge. Before approving that BOM line for internal wiring, it’s worth confirming the exact construction matches the confirmed Style 3122 data below — including the lacquered braid covering, which is a defining feature of this Style.
The Confirmed UL 3122 16 AWG Construction
| Parameter | UL 3122 |
|---|---|
| UL AWM Style | 3122 |
| Description | Single Conductor with Extruded Insulation |
| Featured Conductor Size | 16 AWG (upper end of the Style range) |
| Style Conductor Range | 26 AWG – 16 AWG |
| Conductor Construction | Solid or stranded |
| Temperature Rating | 200°C |
| Voltage Rating | 300 Vac |
| Flame | Horizontal Flame |
| Insulation | Extruded SR (silicone rubber), 15 mils min. average / 13 mils min. at any point |
| Covering | Lacquered Braid |
| Marking | General |
| UL-Defined Use | Internal Wiring |
Horizontal Flame is the confirmed flame requirement — this page does not substitute VW-1, FT1, FT2, or a vertical flame classification for it.
Why the Lacquered Braid Is a Defining Feature
The Lacquered Braid covering is what distinguishes UL 3122 from a plain silicone-insulated wire without a covering — it’s an important identifying feature of this Style, not an optional add-on. The source data available for this page does not specify an exact braid fiber composition, braid thickness, yarn count, weave density, or lacquer chemistry, so none of these are stated here. If your BOM requires a specific braid specification beyond “lacquered braid,” that detail should be confirmed separately before quotation.
Conductor Construction and Material: Confirm Before Quotation
UL Style 3122 permits both solid and stranded conductor construction at 16 AWG — this page does not assume that every 16 AWG order should default to stranded. Conductor material and plating are likewise not established by the Style data; this page does not describe UL 3122 wire as tinned copper, bare copper, nickel-plated copper, silver-plated copper, OFC, or 99.99% copper. If conductor material, plating, or a specific termination method matters to your assembly, specify solid or stranded, the plating requirement, and the termination method in your RFQ rather than assuming a default.
What UL 3122 Defines — and What It Doesn’t
Defined by the Style: temperature rating (200°C), voltage rating (300 Vac), flame requirement (Horizontal Flame), conductor size range (26–16 AWG), conductor construction (solid or stranded), insulation material and minimum thickness (extruded SR, 15/13 mils), covering (Lacquered Braid), and marking (General).
Not defined by the Style — and not stated on this page: conductor plating or material, copper purity, exact strand count, strand diameter, finished outside diameter, conductor resistance, ampacity, bend radius, flex cycles, standard colour, standard reel length, MOQ, lead time, or stock availability. None of these values are invented here — where relevant to your order, specify or confirm them directly.
Where a 16 AWG UL 3122 Specification Fits
The confirmed UL 3122 use is Internal Wiring. Reasonable commercial procurement contexts for this construction include internal leads in temperature-exposed equipment, appliance internal wiring assemblies, internal terminal connections, heating-equipment internal circuits, enclosed equipment harnesses, and OEM internal wiring assemblies. These are application contexts a buyer may bring to this page — they are not an expansion of the UL-defined Use, and this page does not describe UL 3122 as suitable for general external installation, building wire, branch circuit wiring, field wiring, external power cable, portable cord, tray cable, conduit wire, or general power distribution.
