UL 3135 26 AWG Silicone Wire for Totally Enclosed Appliance Thermostat Leads
UL AWM Style 3135 26 AWG silicone rubber wire, rated 200°C and 600 Vac, is a specific conductor-size configuration within Style 3135’s broader 26 AWG–12 AWG range, used for protected internal lead wiring inside totally enclosed appliance thermostat assemblies. This page focuses on the 26 AWG SKU — its confirmed silicone insulation requirement and application boundary — as a defined internal-wiring component, not as a thermostat product itself. UL Style 3135’s confirmed Use is internal wiring of appliances where totally enclosed.

30/27 Mil Silicone Insulation at 26 AWG
The confirmed insulation requirement for UL 3135 is extruded silicone rubber at 30 mils minimum average thickness and 27 mils minimum thickness at any point, applying across the Style’s full 26–12 AWG range — this figure is not tiered by conductor size group, so this page does not invent a separate value specific to 26 AWG. This page does not convert this figure into an invented finished outside diameter; conductor geometry, including finished OD, is order-specific.
26 AWG Is This Page’s SKU — Not a Standard Thermostat Gauge
This page represents the 26 AWG configuration of UL Style 3135; it does not claim that 26 AWG is inherently the standard or preferred gauge for thermostat leads in general. The actual conductor size required for a given thermostat application should always follow the buyer’s approved BOM, wiring diagram, or electrical design — not an assumption based on this page. If your project requires a different AWG within the Style’s 26–12 AWG range, that is a separate SKU.
“Totally Enclosed” Is a Required Installation Condition
This qualifier is central to how UL 3135 must be applied and is preserved throughout this page rather than shortened to generic “internal wiring.” The confirmed UL Use states internal wiring of appliances where totally enclosed — meaning the wire is installed within an appliance construction that fully encloses the internal wiring, not in an open, exposed, or externally accessible installation. This page does not describe UL 3135 as suitable for external thermostat wiring, field-installed thermostat leads, or exposed control wiring outside the appliance enclosure.
Thermostat Lead Wire vs the Thermostat Itself: Where the Specification Boundary Sits
UL AWM Style 3135 defines a wire construction — it does not define, evaluate, or certify a thermostat. This page describes the wire used to connect a thermostat to a terminal, control board, or other internal component within a totally enclosed appliance assembly; it does not make claims about thermostat switching accuracy, temperature-sensing performance, or any electrical characteristic of the thermostat itself. If your BOM references a “thermostat lead” requirement, confirm whether that requirement concerns the wire construction (covered by this page) or the thermostat component (a separate procurement item).
26 AWG Does Not Establish Current-Carrying Capacity
This page does not publish a generic ampacity figure simply because the product is 26 AWG, and does not infer allowable current from the 26 AWG conductor size or the 600 Vac voltage rating — these are separate parameters. Current-carrying suitability depends on the actual conductor construction, thermostat circuit design, ambient conditions, and installation, and must be evaluated accordingly rather than assumed from AWG alone.
Conductor Form, Material, Termination and Connectors: RFQ Fields
UL Style 3135 permits solid or stranded conductor construction at 26 AWG; conductor material and plating are not established by the Style data. This page does not describe UL 3135 26 AWG as a fixed bare-copper or tinned-copper product — if your BOM or drawing specifies a conductor material, plating, terminal, connector, or termination process for the thermostat lead, include that in your RFQ so the corresponding construction can be confirmed.
Common RFQ Gaps for UL 3135 26 AWG Thermostat Leads
Certain specification fields are frequently left out of an initial enquiry and typically require a follow-up before an accurate quotation can be issued. These are common information gaps, not observations about any particular buyer: UL 3135 and 26 AWG are specified but conductor form is missing; conductor plating is required by the termination process but not stated; thermostat type is given but connector details are missing; a finished OD limit is omitted; colour is omitted; a cut length is specified without a tolerance; generic “high flexibility” is requested without a measurable requirement; external thermostat wiring is assumed despite the totally-enclosed appliance boundary; or quantity is stated without a packaging requirement. A complete RFQ reduces supplier interpretation and quotation revisions.
What UL 3135 Does Not Automatically Define
The Style data does not automatically define: conductor material, conductor plating, strand count, strand diameter, conductor resistance, ampacity, current rating, thermostat switching characteristics, finished OD, bend radius, flex cycles, flexibility class, terminal compatibility, connector compatibility, standard colour, cut-length tolerance, reel length, MOQ, stock status, lead time, or production capacity. These remain RFQ, BOM, or ordered-construction details where relevant — none of them are invented on this page.
