UL 5476 — Extended-AWG 600V Mica Tape Wire for UK Heavy Heat Equipment
UL 5476 covers the same 450°C / 600V high-temperature power-class envelope as UL 5335, but extends the AWG range down to 30 AWG (compared to UL 5335’s 22 AWG starting point). This makes UL 5476 the broader-coverage choice when UK manufacturers need both heavy power-class conductors (1/0-4/0 AWG) and finer signal/control conductors (30-22 AWG) within the same UL Style designation.
For UK manufacturers searching UL 5476 Mica Tape Leitung UK supplier, this AWG range flexibility simplifies UL Listing documentation: a single Style number (5476) covers the entire wiring range from instrumentation leads through main power feeds in 450°C / 600V high-temperature equipment.
UK Heavy Heat Equipment Sectors Specifying UL 5476
UK Industrial Furnace Manufacturers — Large UK industrial furnace producers (aerospace heat treatment, metal hardening, specialty ceramic firing) use UL 5476 for both 480V three-phase main feeds (1/0-4/0 AWG range) and instrumentation/control circuit wiring (16-22 AWG range) inside the same equipment. The unified UL Style designation simplifies the UL Listing component declaration.
UK Glass Production Equipment — UK glass tempering and annealing equipment manufacturers exporting to North American architectural and automotive glass markets use UL 5476 for heating element power circuits and temperature monitoring signal wiring within their equipment.
UK Industrial Boiler and Heat Exchanger Manufacturers — UK manufacturers of industrial boiler equipment and process heat exchangers serving North American chemical, food processing, and pharmaceutical industries use UL 5476 for high-temperature internal wiring at 600V class.
UK Port Options and Logistics
CableApex ships UL 5476 to three UK port options based on destination preference:
Felixstowe — Default choice, highest sailing frequency from Shanghai/Ningbo, lowest CIF rate, optimal for Midlands and Northern England destinations.
Southampton — Better for South England and Manchester destinations, strong rail inland connectivity.
London Gateway — Optimal for Greater London and Southeast England destinations.
Transit time 28-32 days from Shanghai/Ningbo to UK ports, with documentation set including UK customs requirements and UK VAT handling notes for first-time importers.

Engineering Notes from CableApex
- “UL 5476 vs UL 5335 — which should I specify?” Both Styles cover 450°C / 600V mica wire. UL 5335 ranges 22-4/0 AWG; UL 5476 ranges 30-4/0 AWG (extending to finer 30, 28, 26 AWG conductors). For applications needing only 22 AWG and larger, UL 5335 is the traditional choice. For applications mixing power-class and signal-class conductors within the same equipment under a single Style designation, UL 5476’s broader AWG range simplifies the UL Listing dossier.
- “Can I order UL 5476 in both fine and heavy gauges in the same shipment?” Yes. Multi-AWG consolidation is standard for UL 5476 orders. A typical UK industrial furnace manufacturer’s order might combine 1,000m of 4 AWG (main power feeds), 2,000m of 14 AWG (heating element control), and 500m of 22 AWG (sensor leads) in a single container shipment with consolidated documentation.
- “UKCA marking implications for UL 5476?” UKCA marking applies to finished products in the UK market, not to internal wiring components. UL 5476 wire requires no UKCA mark. Your finished equipment requires UKCA assessment for UK market sales, while continuing to need CE for EU and UL Listing for US/Canada exports. UL 5476’s UL Recognition supports the UL Listing track without affecting the UKCA or CE assessment processes.
MOQ, Packaging & Shipping
MOQ varies by AWG, conductor count requirements, and production schedule. Multi-AWG consolidation orders typically achieve better economics. Standard packaging: spools or reels per customer specification. UK export documentation: Commercial Invoice (GBP optional), Packing List, Certificate of Origin (CCPIT), Bill of Lading, UL Recognition reference letter (File No. E333030), RoHS Declaration, REACH SVHC Declaration, MSDS. HS Code: 8544.49. CIF Felixstowe, Southampton, or London Gateway, transit time 28-32 days from Shanghai or Ningbo.
