UL 3321 6 AWG XLPE Power Wire Overview
UL AWM Style 3321 is a single-conductor XLPE insulated wire construction, supplied by CableApex as a factory-direct manufacturer. This page focuses specifically on the 6 AWG configuration within Style 3321’s broader 30 AWG–4/0 AWG conductor range. The wire is rated 150°C, 600 Vac and 750 Vdc, with extruded XLPE insulation applied at the Style’s 8–4 AWG thickness band for the featured 6 AWG size. UL defines the Style’s use as internal wiring of appliances; “power wire” and “high-temperature appliance power connection” are CableApex’s commercial positioning for this product, not UL’s own terminology.

6 AWG High-Temperature Appliance Power Wiring
This page focuses specifically on the 6 AWG configuration within UL Style 3321’s 30 AWG–4/0 AWG conductor range. The featured combination — 6 AWG, XLPE insulation, 150°C, 600 Vac / 750 Vdc, and the applicable 45 mil insulation wall — differentiates this page from a general Style 3321 overview. We do not publish an ampacity figure, current-carrying capacity, recommended continuous amps, or breaker or fuse size for 6 AWG or any AWG; current-carrying requirements depend on the equipment design, installation conditions, and applicable end-equipment evaluation, not on AWG alone.
45-Mil XLPE Insulation Requirement
6 AWG falls within Style 3321’s 8–4 AWG insulation band, which specifies a minimum average XLPE thickness of 45 mils and a minimum thickness of 40 mils at any point. This is distinct from the Style’s other bands — the 30–9 AWG band specifies 30 mil average / 27 mil minimum, the 3–2 AWG band specifies 60 mil average / 54 mil minimum, and the 1–4/0 AWG band specifies 80 mil average / 72 mil minimum — and this page uses only the values applicable to the featured 6 AWG size. We do not calculate or publish a finished outside diameter from AWG and insulation thickness, as conductor geometry and production tolerances are not part of the confirmed technical basis for this page.
Optional Braid Covering
UL Style 3321 permits an optional treated or untreated braid covering over the XLPE-insulated conductor. This covering is optional — the basic UL 3321 6 AWG construction is XLPE-insulated wire without a braid, and not every order automatically includes one. The supplied Style record identifies the covering only as “treated or untreated braid” without specifying a fiber material, so this page does not name it as fiberglass, aramid, or polyester braid, and does not claim that the braid provides abrasion certification, cut resistance, chemical resistance, moisture resistance, or flame enhancement — none of these are established by the Style-level record. Specify your braid requirement, if any, when requesting a quotation.
UL 3321 Technical Specifications
See the specification table above for the complete confirmed ratings applicable to this featured 6 AWG product.
Appliance Internal Power Wiring Applications
UL Style 3321’s confirmed use is internal wiring of appliances. Appropriate commercial application language for this page includes appliance internal power wiring, internal appliance power connections, protected internal electrical connections, high-temperature appliance power leads, internal component-to-component power connections, and OEM appliance internal wiring where Style 3321 is specified. This page does not broaden the use into building wiring, branch circuits, feeder cable, field wiring, tray cable, conduit cable, external appliance cord, or utility distribution, and does not position UL 3321 as generic industrial power cable — final acceptability for any specific installation depends on the equipment design and applicable end-product requirements.
UL 3321 vs Other Power-Wire Insulation Systems
UL Style 3321’s XLPE insulation and 150°C rating distinguish it from CableApex’s other power-wire Styles. Our UL 1283 8 AWG PVC Power Wire uses PVC insulation rated 105°C / 600 Vac — a lower temperature rating in a different material family. Our UL 1330 4 AWG FEP Power Wire uses FEP insulation rated 200°C / 600 Vac — a higher temperature rating than UL 3321, in a fluoropolymer rather than a thermoset material. Our UL 1032 2 AWG PVC Power Wire is rated 90°C, 1000 Vac / 1200 Vdc — differentiated primarily by higher voltage and a large PVC construction rather than by temperature or material. UL 3321 also differs from UL 3271, a separate XLPE Style rated 125°C / 600 Vac / 750 Vdc with a use statement that includes motor leads — this page does not target that Style or its motor-lead positioning. Select based on the confirmed Style, material, rating, and conductor size your application actually requires rather than treating these Styles as interchangeable.

UL Marking and Documentation
Qualifying UL AWM Style 3321 constructions can be supplied through the relevant qualified manufacturing scope for this Style. UL marking and documentation are confirmed according to the qualified Style 3321 construction supplied for the order and are not identical across every commercial variation. RoHS and REACH are separate regulatory frameworks from UL recognition; applicable RoHS / REACH documentation requirements can be confirmed according to the ordered construction.
