Industry insight and technical deep-dives from our engineering team
Why Where Your Power Cords Are Made Matters More Than It Used To
The global cable industry saw 35%+ cost increases and significant supply delays in 2023-2024. A hyperscaler building a new AI data center cannot wait 16 weeks for cords. Here is why domestic manufacturing became a competitive differentiator.
52% of Data Center Outages Start with Power. Here Is the Part Nobody Audits.
Uptime Institute research is consistent year after year: power is the leading cause of data center failures. We talk endlessly about UPS, generators, and PDUs. Almost nobody talks about the cords.
C13 vs. C15: The Temperature Rating That Is Quietly Failing Data Center Equipment
C13 and C15 connectors look almost identical and are physically compatible in most scenarios. The difference -- 70C vs. 120C temperature rating -- seems academic until your hot aisle hits 45C and you start doing the math on derating curves.
The Power Cord Problem That AI Created -- And Nobody Is Talking About
Traditional data center racks drew 5-12 kW. NVIDIA GB200 racks draw 132 kW. The infrastructure that was fine last year is not fine anymore -- and the cord choices you make today determine whether your facility handles what is coming in 2026.
Global Product Approval Agencies for Power Cords
Governments around the world adopt standards for products in order to ensure proper systems and practices are in place to deliver quality goods to customers using the goods within the country.
What is a Grounding Conductor and Why Do Power Cords Have Them?
The purpose of grounding conductors is to provide the path of least resistance from the electrical source back to the ground. Properly sized grounding conductors protect personnel from electric shock. In order to understand how grounding conductors work, you must first understand how they came to be.
