UL 1332 200°C 300V FEP 30–10 AWG Wire for Appliance Internal Wiring

UL 1332 200°C 300V FEP Wire for Appliance Internal Wiring

This page covers UL AWM Style 1332, a single conductor with covering, insulated with extruded FEP and rated 200°C and 300 Vac with a Horizontal Flame designation. It is written for appliance and equipment OEM engineering and procurement teams whose drawing, BOM or wire specification calls for Style 1332.

The conductor range is 30 AWG–10 AWG, solid or stranded round, Marking is General, and the official Use is “Internal wiring of appliances.” The Style also carries optional oil and gasoline resistance ratings, an optional covering, and a set of tag indications that are frequently misquoted as standard ratings.

The sections below separate three layers: the ratings and construction the Style fixes, the options that apply only when specified, and the parameters that belong to the ordered construction rather than to the Style.

Confirmed UL Style 1332 Construction and Ratings

Ten points to clarify about the table above:

1. The insulation is extruded FEP. PTFE, TFE, PFA and ETFE are different materials and are not this Style.
2. The temperature rating is 200°C, stated without a duty qualifier, and the voltage rating is 300 Vac. The record gives no DC rating.
3. The insulation requirement is 13 mil minimum average and 12 mil minimum at any point. These are two independent minimums, uniform across the conductor range.
4. The oil resistance rating is optional and is stated at 80°C, separate from the 200°C Style temperature rating.
5. The gasoline resistance rating is also optional and independent of the oil rating.
6. The covering is optional, and the record permits either an extruded FEP covering of 2 mils or heavier, or a glass braid of 7 mils or heavier.
7. Those covering figures are minimums for the option chosen. They are not a combined build and not a nominal thickness.
8. The tag indications are tag statements for a qualified construction, not normal ratings carried by every Style 1332 wire. “600 volts peak for electronic use only” in particular is not the working-voltage rating, which remains 300 Vac.
9. Conductor material, plating, strand count, strand diameter and lay length are not defined by the Style.
10. Finished OD, OD tolerance, conductor resistance, metric cross-section and ampacity are not defined by the Style, and the Style range is not a stock list.

FEP Insulation and the 13/12 mil Wall

The insulation is extruded FEP, with a 13 mil minimum average thickness and a 12 mil minimum thickness at any point. Both conditions apply together, and neither is a nominal wall. Unlike Styles that group the wall by conductor size, Style 1332 applies the same two minimums across the whole 30 AWG–10 AWG range, so the requirement does not change with the ordered size.

What does change with size is the finished dimension, and minimum wall values do not produce one. Actual OD depends on the conductor material and form, the actual conductor diameter, whether the optional covering is applied and which type, the FEP extrusion and manufacturing tolerance. Where connector entry, sleeve fit or routing clearance is controlled, state a maximum finished OD and OD tolerance in the RFQ so the proposed construction can be checked against it.

FEP belongs to the fluoropolymer family, but this page keeps FEP as the material identity rather than substituting the family name, and it does not transfer properties published for PTFE, PFA or other fluoropolymers to this Style. Beyond the optional oil and gasoline ratings described below, no chemical, solvent, moisture, low-friction, dielectric constant or outgassing property is attributed to the insulation, because the record states none.

The Optional Covering

The Product Description names a covering, and the record defines it as an option with two permitted forms: an extruded FEP covering of 2 mils or heavier, or a glass braid of 7 mils or heavier.

Three points follow. The covering is not automatic, so an enquiry that requires one should say so. The two forms are alternatives with different minimums, so a drawing controlling the covering should name which form is required. And each figure is a floor for that form, not a nominal or typical thickness, so a quoted construction may exceed it.

The record assigns the covering no function. This page therefore does not describe either form as providing mechanical protection, abrasion resistance, improved flame behaviour or a dielectric contribution, and the glass braid in particular is not presented as a protective layer.

Optional Oil and Gasoline Resistance, and the Tag Indications

Two optional ratings appear in the record: Oil Resistant 80°C and Gasoline Resistant. Each is supplied only where specified and confirmed for the ordered construction, and neither implies the other. The oil rating is stated at 80°C, which is separate from the 200°C Style temperature rating, so oil exposure at a higher temperature is not established by this Style.

Separately, the record states that the tag may also indicate: suitable for immersion in gasoline; gasoline vapor; 80°C in oil; and / or 600 volts peak for electronic use only. These are tag statements applying to a qualified construction, written with “and / or”, so a given construction may carry some, all or none of them.

Two cautions follow. Immersion and vapor statements are not blanket chemical compatibility claims, and this page does not extend them to fuels, solvents, coolants or additives not named in the record. And “600 volts peak for electronic use only” keeps both qualifiers whenever it is cited: it is a peak indication for electronic use rather than a working voltage, and the normal voltage rating remains 300 Vac.

Conductor Range and Construction

The Style covers 30 AWG through 10 AWG, solid or stranded round. Listings showing a wider span describe sizes the Style does not cover, and an enquiry built on such a listing will not match a qualified Style 1332 construction.

The following are RFQ fields rather than Style values:

• solid or stranded form
• conductor material
• plating or surface finish, such as silver-plated or nickel-plated constructions where the drawing requires one
• strand count, strand diameter and lay construction, where controlled
• maximum conductor resistance, where controlled
• metric cross-section, where a drawing specifies mm² rather than AWG

No stranding class, flexibility grade or flex life is applied here. Conductor size assigns no circuit function or current capacity either: the record gives no ampacity, and none is inferred from conductor size, the 200°C rating or the 300 Vac rating. Current-carrying capacity is evaluated through the buyer’s equipment design and the applicable approval process.

Official Use: Internal Wiring of Appliances

The official Use is “Internal wiring of appliances.” This page keeps that wording and does not extend it to building or field wiring, branch-circuit or facility wiring, conduit or tray installations, external equipment wiring, portable cord, fuel system components, or interconnection between separate enclosures.

Enquiries often arrive from contexts such as appliance interiors with elevated temperatures, sensor and instrumentation assemblies, control assemblies, or equipment where incidental oil or fuel exposure is a design concern. Those are buyer enquiry contexts that can be reviewed against the drawing, and they do not change the Use. The optional resistance ratings and tag indications describe properties of a qualified wire construction; they do not turn the wire into a fuel system or automotive component, and compliance of a finished appliance is established at the equipment level rather than by the Style designation of one internal wire.

How to Specify UL 1332

A Style designation is a construction requirement, not a complete purchase specification. A complete enquiry adds:

• the UL AWM Style 1332 requirement
• the AWG within 30 AWG–10 AWG
• solid or stranded round conductor
• conductor material and plating, where controlled by the drawing
• strand construction and maximum conductor resistance, where controlled
• whether the optional Oil Resistant 80°C rating is required
• whether the optional Gasoline Resistant rating is required
• whether a covering is required, and whether extruded FEP or glass braid
• which tag indications the design requires
• insulation colour and any identification requirement
• the marking requirement
• maximum OD and OD tolerance, where controlled
• the appliance internal wiring location
• the drawing, BOM or equipment specification
• documentation requirements, quantity and packaging preference
• the destination and the requested Incoterm

No price, currency, pricing formula or price validity period is published on this page. A quotation is prepared against a defined construction and commercial scope and issued as a separate quotation document.

What Style 1332 Does and Does Not Define

Style 1332 defines:

• 200°C temperature rating and 300 Vac voltage rating
• Horizontal Flame
• optional Oil Resistant 80°C and optional Gasoline Resistant ratings
• a single conductor with covering, conductor range 30 AWG–10 AWG, solid or stranded round
• extruded FEP insulation, 13 mil minimum average / 12 mil minimum at any point
• an optional covering of extruded FEP at 2 mils or heavier, or glass braid at 7 mils or heavier
• Marking: General
• Use: Internal wiring of appliances.
• the tag indications for gasoline immersion, gasoline vapor, 80°C in oil, and / or 600 volts peak for electronic use only

Style 1332 does not universally define:

• conductor material, plating, strand count, strand diameter or lay length
• a function for the optional covering
• finished OD, OD tolerance, bend radius, flex cycles or flex class
• conductor resistance, ampacity, current rating or metric cross-section
• a DC voltage rating
• chemical or solvent compatibility beyond the optional ratings and tag indications as stated
• dielectric constant, outgassing or low-friction properties
• fuel system, automotive, aerospace, medical or laboratory qualification
• colour, reel length, MOQ, stock, lead time, production capacity or shipping term

Common Procurement Errors

• Describing the insulation as PTFE, PFA or ETFE, or substituting “fluoropolymer” for the FEP identity.
• Treating the optional oil or gasoline resistance as standard on every Style 1332 wire.
• Applying the 200°C rating to the oil resistance, which is stated at 80°C.
• Reading the tag indications as normal ratings, or as general chemical compatibility.
• Using 600 volts peak as the working voltage, or dropping “for electronic use only”.
• Assuming a covering is included, or mixing the 2 mil and 7 mil figures across the two covering forms.
• Attributing mechanical protection or abrasion resistance to the covering.
• Omitting the 12 mil minimum-at-any-point requirement, or treating 13 mil as a nominal wall.
• Deriving a finished OD from the minimum wall values.
• Extending the conductor range beyond 30 AWG–10 AWG.
• Assuming the conductor is silver-plated or nickel-plated copper without stating it.
• Deriving ampacity from conductor size or the ratings.
• Presenting the wire as a fuel system or automotive component.
• Treating component Style recognition as equipment-level compliance.
