Cablelera AC Power Cord: C19 From C20, 3ft
Best for compact data-center racks needing a short link between a C20 outlet and a C19 device. The 12AWG conductors support up to 20A at 250V, making it suitable for high-powered servers or PDUs in constrained spaces. This is a dedicated short-extension, not a long-haul cable, which helps reduce voltage drop and clutter inside cabinets.
Who it’s best for: IT technicians performing in-rack migrations or reconfigurations where space is at a premium. Limitations: Not designed for long-distance runs or external power feeds.
Cablelera NEMA 5-15P to IEC 320 C19, 6ft
Best for IEC C19 inlet equipment connected to standard NEMA 5-15 outlets, with clear electrical ratings. This 6-foot cord uses 14AWG conductors and is rated 15A at 125V. It is not suitable for C20 inlets or 20A/250V applications, so choose this when your equipment and outlet match 125V/15A.
Who it’s best for: Facilities needing a simple US-standard to C19 cord for lower-power devices. Limitations: Not compatible with higher-current or 250V equipment.
Strhowill C19 Female Rewirable Connector
Best for custom cable builds where exact length or routing is required. This 16A 250V AC C19 receptacle is solderless and rewirable, suitable for IT cabinets, PDUs, and industrial equipment. It supports 12AWG to 3x12AWG configurations with copper contacts and CE/REACH/RoHS compliance.
Who it’s best for: Technicians creating bespoke power cables. Limitations: Requires solder-free assembly and appropriate tooling.
Strhowill NEMA 5-15P to C19, 3.2ft
Best for US-standard outlets feeding C19 devices, combining standard 5-15P male with a C19 female. The 3.2-foot length fits under desks or inside racks without excess slack. The product notes emphasize RoHS compliance and UL listing, making it a safe, practical option for general IT setups.
Who it’s best for: Offices or smaller labs needing a short, compliant cord. Limitations: Not suitable for 20A/250V or non-C19 equipment.
Toptekits C19 to NEMA L6-20P, 10ft
Best for longer runs and secure connections in high-demand environments. This 10-foot cord uses a locking NEMA L6-20P plug to IEC320 C19 and is rated at 20A/250V. It features heavy-duty construction with 12AWG conductors for robust performance. The locking plug helps resist accidental disconnection in busy racks.
Who it’s best for: Data centers or large equipment rooms needing a stable, longer reach. Limitations: Locking plug can be less convenient for quick disconnects in tight spaces.
Plugrand IEC 19 Plug (C19), 20A/125V or 20A/250V
Best for equipment patches requiring a robust C19 end, especially in UPS or PDUs. This ETL-verified C19 plug supports both 125V and 250V operation with various conductor sizes; it is designed to accommodate 12AWG up to 14AWG cords per strain-relief options. It is a practical replacement end for custom cables.
Who it’s best for: Techs replacing or upgrading C19 outlets on existing cables. Limitations: Check your cord thickness and strain-relief compatibility before use.
Buying Guide
Key considerations when selecting IEC 320 C19 PDU extensions include:
- Voltage and current rating: Match the device inlet rating (often 16A or 20A at 125V or 250V) to avoid overheating or nuisance trips.
- Conductor gauge: Heavier gauges (12AWG) handle higher current with less voltage drop, especially for longer runs.
- Plug and receptacle type: Consider locking L6-20P vs. standard C20/C19 connectors for stability in racks or environments with vibrations.
- Length: Short cords reduce clutter and voltage drop; longer cords support larger rooms but must maintain safe routing.
- Rewirable or pre-fabricated: Rewirable options offer customization; pre-fabricated cords are ready to use but less flexible.
- Safety certifications: Look for UL, CE, RoHS, and ETL listings to ensure compliance and safety in data-center settings.
- Compatibility: Confirm inlet/outlet types on the equipment and PDUs to ensure a proper fit (C19 to C20, C19 to NEMA variants, etc.).
Frequently Asked Questions
- What is IEC 320 C19 used for?
– It is a standard connector for high-power IT equipment, PDUs, and UPS units, typically on 16A or 20A circuits at various voltages. - Can I use a C19 cord with a C13 device?
– No. C19 is designed for C19 inlets/outlets; C13 is a different connector pair. - Is a locking plug better for data centers?
– Locking plugs like L6-20P provide added retention in busy racks, reducing accidental disconnections. - Should I choose a 10ft cable or a 3ft cable?
– Choose based on distance and cable management needs. Shorter cords reduce clutter; longer cords cover larger spaces. - Are rewirable C19 connectors safe?
– They can be safe when assembled with proper tools and following safety standards; safety shutters and copper contacts add protection.
