16 AWG vs 18 AWG — UL 1007 Sizing Decision for German OEMs
UL 1007 covers the AWG range from 32 AWG to 16 AWG per UL Subject 758. 16 AWG is the largest conductor in the UL 1007 family — anything heavier than 16 AWG falls outside the UL 1007 listing and requires a different AWM style (typically UL 1015 or UL 1569 for 14 AWG and below). German OEMs searching UL 1007 16 AWG Innenverdrahtung Draht Deutschland Preis are typically engineers facing one of three sizing decisions:
- 18 AWG is undersized for the load. The end-equipment circuit draws more than 7A continuous, and 18 AWG would run hot inside the cabinet. 16 AWG (~1.31 mm²) at 80°C provides margin up to roughly 10A continuous in still-air cabinet applications.
- Mechanical robustness needed. The wire is routed through tight bends, near moving components, or subject to vibration during equipment operation. 16 AWG has greater pull strength and longer flex life than 18 AWG.
- Voltage drop matters on long internal runs. In larger appliances or commercial equipment with internal wire runs over 2 meters, 18 AWG may exceed acceptable voltage drop. 16 AWG reduces resistance per meter by approximately 37%.
If any of the three conditions apply, 16 AWG is the right specification within the UL 1007 family. If none apply, 18 AWG is the cost-effective choice — both are listed under the same E333030 file with identical insulation specification.
Typical German OEM Innenverdrahtung Applications for 16 AWG
Haushaltsgeräte — Larger Appliances
German appliance manufacturers producing washing machines, dishwashers, and electric ovens for the US market use UL 1007 16 AWG for internal wiring between the mains terminal block and the motor controller, heating element relay, or pump assembly. The 300V rating provides safety margin over 120V residential supply, and 80°C PVC handles ambient temperatures inside the appliance housing. Heating element direct connections typically use UL 1015 or UL 1569 at 105°C, but the upstream mains and control circuits commonly use UL 1007 16 AWG.
Kommerzielle Küchengeräte — Commercial Kitchen Equipment
German commercial kitchen equipment OEMs producing combi ovens, dishwashers, and food preparation equipment for North American distribution specify UL 1007 16 AWG for control circuit wiring inside equipment housings. The combination of 300V rating and 16 AWG current capacity covers the majority of internal control connections without requiring the higher cost of UL 1015.
Medizingeräte — Medical Equipment Internal Wiring
German medical equipment OEMs producing dental units, laboratory equipment, and small diagnostic devices for the US FDA-regulated market use UL 1007 16 AWG inside equipment housings where the end-product is UL 60601-1 listed. UL 1007 as a UL Recognized component is acceptable inside the UL 60601-1 system listing, provided the wire is correctly applied within its voltage and temperature ratings.
Was Treibt Den Preis pro Meter — Pricing Drivers for 16 AWG
Per-meter pricing on UL 1007 16 AWG is driven by three variables, in order of impact:
- Copper conductor cost. 16 AWG carries roughly 60% more copper per meter than 18 AWG, making copper the dominant cost component. CableApex tracks daily LME copper settlement and offers index-linked quotations for orders above 10,000 m to lock the copper component during the 25–30 day Hamburg/Rotterdam transit.
- PVC compound and wall thickness. UL 1007 16 AWG sits in the 32–16 AWG range with insulation specified at 15 mils (0.38 mm) minimum average wall per UL Subject 758. PVC compound cost is relatively stable but varies between 80°C grade (default for UL 1007), 90°C grade, and oil-resistant grades.
- Color, MOQ, and packaging. Standard color orders (black, white, red, blue) carry the lowest premium. Custom colors, multi-color striping, or printed identification add setup cost. Container-quantity orders (typically 50,000+ m mixed AWG) achieve the lowest per-meter rate.
For an accurate per-meter quotation, German buyers should specify total quantity, color breakdown, conductor type (bare or tinned copper), and target arrival window. Contact CableApex for a current quotation referencing the LME copper settlement of the quotation date.

Engineering Notes from CableApex
Three points German OEM engineers raise specifically about 16 AWG UL 1007:
- “Why does my BOM call out UL 1015 16 AWG instead of UL 1007 16 AWG?” UL 1015 also covers 16 AWG (the UL 1015 range is 30 AWG to 2000 kcmil, so 16 AWG sits well within it). The choice between UL 1007 16 AWG and UL 1015 16 AWG is voltage and temperature: UL 1007 = 300V/80°C, UL 1015 = 600V/105°C. If your BOM specifies UL 1015 16 AWG, the original designer wanted the higher voltage or temperature margin. Substituting UL 1007 is a downgrade and may cause UL re-evaluation if discovered during inspection.
- “Can I use 16 AWG UL 1007 for the line cord on a US appliance?” No. Line cords (the external power cable) require UL 62 / UL 817 listed cord types (SJT, SJTW, SVT, etc.), not AWM. AWM is only for internal wiring inside the appliance enclosure. Using UL 1007 as a line cord is a code violation and a UL listing failure.
- “Bare vs tinned copper for 16 AWG hook-up?” For factory crimp termination during appliance assembly, bare copper is standard and lowest cost. For field-serviceable connections, soldered terminations, or applications in humid/coastal end-markets, tinned copper provides better long-term contact integrity at modest premium.
