UL 3666 10 AWG Tinned Copper XLPE Wire Overview
This page covers UL AWM Style 3666 XLPE insulated wire in a 10 AWG tinned copper construction, supplied by CableApex as a factory-direct manufacturer. UL Style 3666 covers a broad conductor range of 32 AWG through 1000 kcmil, solid or stranded round, in tinned or bare copper; this page focuses specifically on the 10 AWG tinned copper construction. Buyers requiring a different gauge or a bare copper finish within the Style range should confirm their specific requirement during quotation.
UL 3666 10 AWG tinned copper XLPE wire is a single-conductor construction rated 105°C and 600 Vac, intended for internal wiring where the wire is not subjected to mechanical abuse. Conductor stranding details, insulation colour, and packaging are confirmed according to the ordered specification.

10 AWG Tinned Copper Conductor Configuration
This page focuses specifically on the 10 AWG conductor size supplied with a tinned copper finish, one of the two conductor finishes explicitly permitted under UL Style 3666. Tinned copper is the selected finish for this product; actual stranding details — solid or stranded, strand count, and strand diameter — are confirmed according to the ordered construction rather than published as generic figures on this page. We do not state a specific copper purity, conductor resistance, or current-carrying capacity, as these depend on the actual ordered construction. If a bare copper finish or a different gauge is required, confirm this when requesting a quotation.
XLPE Insulation and 15/13 Mil Wall Requirements
Insulation is XLPE (cross-linked polyethylene), applied at the Style’s minimum thickness requirements for the 32–10 AWG range: 15 mil minimum average and 13 mil minimum at any point. Insulation colour should be specified and confirmed with your order. We do not publish a finished outside diameter, dielectric strength, elongation, tensile strength, or flex-life figure on this page, as these depend on the actual ordered construction and are not established by the Style-level record.
Protected Internal Wiring Application Boundary
UL Style 3666 is designated for internal wiring where the wire is not subjected to mechanical abuse. This means the wire is intended for installation inside an enclosure or assembly where it is protected from physical stress, flexing, or impact during normal service. This is the application boundary for the product supplied from this page. It is not intended as building wire, field wiring, or general external power cable, and this page does not position the product for a specific end application such as inverters, power supplies, or PV systems — its differentiation is based on specification, not application marketing.
UL Marking and Documentation Requirements
Qualifying UL AWM Style 3666 constructions can be supplied through the relevant partner manufacturing scope associated with the applicable UL Recognized Component file on record. UL marking and related documentation depend on the specific qualified construction ordered; not every configuration automatically carries a UL Mark, and marking requirements should be confirmed when requesting a quotation. We do not guarantee that a given shipment will pass a customer’s internal or third-party audit, building-code review, or regulatory approval.
RoHS and REACH are separate regulatory frameworks from UL recognition and are not treated as equivalent certifications on this page. Applicable RoHS / REACH documentation, where required, is confirmed according to the ordered materials and your documentation requirements.
