​​Understanding the CAB-AC-20A-SG-US= Power Cable​​

The ​​CAB-AC-20A-SG-US=​​ is a Cisco-certified 20A AC power cable designed to meet the rigorous electrical standards of both the United States (NEMA) and Singapore (SS 145). According to Cisco.com, this cable supports high-current devices like Catalyst 9500 switches, UCS C4800 M7 servers, and other infrastructure requiring stable 20A input in regions with demanding power requirements.

​​Technical Specifications and Regional Compliance​​

• ​​Voltage Range​​: 100–240 VAC, 50/60 Hz, compatible with U.S. 120/208V and Singapore’s 230V grids.
• ​​Connectors​​: C20 (device end) to NEMA L6-20P (U.S.) or SS 145 (Singapore) plugs, ensuring localized socket compatibility.
• ​​Certifications​​: UL 60320 (U.S.), SS 145 (Singapore), and IEC 60320-C20, validated by Cisco for high-power hardware.
• ​​Durability​​: 3-meter length with heavy-duty insulation, rated for 0–60°C and 85% non-condensing humidity.

​​Why the CAB-AC-20A-SG-US= Is Irreplaceable​​

​​1. Dual-Region Compliance​​
Deploying non-compliant cables in the U.S. or Singapore risks violating local electrical codes, voiding Cisco warranties, or triggering safety audits. This cable bridges both markets seamlessly.

​​2. Support for Power-Intensive Workloads​​
Devices like Catalyst 9500 switches with PoE++ (90W per port) or UCS servers running AI/ML workloads require 20A input. Generic cables may fail under sustained loads, causing overheating or shutdowns.

​​Key User Questions Answered​​

​​Q: Can I use this cable for 16A devices like Catalyst 9400 switches?​​
A: Yes, but only if the device supports C20 inlets. However, Cisco.com recommends matching amperage to avoid underutilization or future scalability issues.

​​Q: Is it safe to use the U.S. plug variant in Singapore?​​
A: No. The NEMA L6-20P plug is incompatible with Singapore’s SS 145 outlets. Always select the region-specific variant for compliance.

​​Q: How does humidity affect performance in tropical climates?​​
A: The cable’s insulation is tested for Singapore’s humidity, preventing corrosion in high-moisture environments common in data centers.
