UL 1332 22 AWG FEP Wire for Appliance Internal Control Leads
UL AWM Style 1332 22 AWG FEP wire, rated 200°C and 300 Vac, is a specific conductor-size configuration within Style 1332’s broader 30 AWG–10 AWG range, used for protected internal control-lead wiring inside appliance assemblies. This page focuses on the 22 AWG SKU — its confirmed FEP insulation requirement and application boundary — as a defined appliance internal wiring product; UL Style 1332’s confirmed Use is internal wiring of appliances, not industrial control-cabinet field wiring, and this page does not position the product around that broader field-wiring context.

13/12 Mil FEP Insulation at 22 AWG
The confirmed insulation requirement for UL 1332 is extruded FEP at 13 mils minimum average thickness and 12 mils minimum thickness at any point, applying across the Style’s full 30–10 AWG range — this figure is not tiered by conductor size group, so this page does not invent a separate value specific to 22 AWG. This page does not convert this figure into an invented finished outside diameter; conductor geometry, including finished OD, is order-specific.
Appliance Internal Wiring, Not Industrial Control-Cabinet Field Wiring
This distinction matters for accurate specification. UL Style 1332’s confirmed Use is internal wiring of appliances — protected internal leads connecting control modules, terminal blocks, or components inside an appliance assembly. It is not the same application category as industrial control-cabinet field wiring, panel-to-panel field wiring, or general electrical-enclosure field installation, which typically fall under different wiring standards. If your project is genuinely an industrial control-cabinet field-wiring application rather than protected internal wiring within an appliance, that application should be evaluated against the applicable wiring standard for that use rather than assumed to be covered by UL 1332.
22 AWG Does Not Establish Current-Carrying Capacity
This page does not publish a generic ampacity figure simply because the product is 22 AWG, and does not infer allowable current from the 22 AWG conductor size or the 300 Vac voltage rating — these are separate parameters. Current-carrying suitability for a control lead depends on the actual conductor construction, control-module load, ambient conditions, and installation, and must be evaluated accordingly rather than assumed from AWG alone.
300 Vac Base Rating vs the Optional 600 V Peak Marking
UL 1332’s primary continuous voltage rating is 300 Vac. A qualified UL 1332 construction may separately carry an optional tag stating “600 V Peak — For Electronic Use Only.” This optional peak designation is not the same as a continuous 600 Vac rating. If your BOM references 600 V for this product, confirm whether it is referring to this optional peak tag or an actual continuous voltage requirement.
Conductor Form, Material, Termination and Connectors: RFQ Fields
UL Style 1332 permits solid or stranded conductor construction at 22 AWG; conductor material and plating are not established by the Style data. This page does not describe UL 1332 22 AWG as a fixed bare-copper or tinned-copper product — if your BOM or drawing specifies a conductor material, plating, terminal, or connector requirement for control-module interconnection, include that in your RFQ so the corresponding construction can be confirmed.
Optional Covering
UL Style 1332 permits an optional covering over the FEP-insulated conductor — either extruded FEP at 2 mils or heavier, or glass braid at 7 mils or heavier. This is not standard on every UL 1332 22 AWG order; if your application requires a covering, specify which type in your RFQ.
Common RFQ Gaps for UL 1332 22 AWG Control 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: 22 AWG is specified but solid or stranded is not stated; conductor finish is required by the BOM but omitted; an OD limit is missing; colour is missing; connector or terminal specification is missing; an optional covering is assumed but not stated; 600 V is requested because the optional peak marking was misunderstood; quantity is stated without a reel or packaging requirement; or a cut length is stated without a tolerance. Complete inputs make quotations more comparable.
What UL 1332 Does Not Automatically Define
The Style data does not automatically define: conductor material, conductor plating, strand count, strand diameter, conductor resistance, ampacity, current rating, finished OD, bend radius, flex cycles, flexibility class, terminal compatibility, connector compatibility, standard colour, reel length, cut-length tolerance, MOQ, stock, lead time, or production capacity. These remain RFQ or ordered-construction details where relevant — none of them are invented on this page.
