Things You Should Know About Data Center Wiring And Power Systems

There are a lot of things you should know about data center wiring and power systems. This blog covers a few of them, how they work and what companies should be aware of.

How They Work

Electricity is the lifeblood of a data center. It powers servers with super-smart CPUs, memory and storage to keep the entire facility running smoothly. Power flows from a utility source into the building via automatic transfer switches and then to the power distribution units (PDUs) that supply IT equipment. These systems are backed up by backup generators that switch into action in the event of a power outage, providing emergency power to support critical servers and other equipment. To minimize transmission losses, IT equipment racks are typically powered with 400V three-phase power instead of 208V/120V. This is a much more stable voltage that can handle the load and maintain a high performance.

Types of Cables

There are a few different types of cables used in data center power and cable systems. These include G-GC, W, tray cables and more. Aside from supplying power, the cables also play a crucial role in grounding the system. It is important to install quality grounding cables since this ensures safety in the data center. Copper cabling is a good choice for data centers as it is cheaper and easier to maintain than fibre optics. It can transmit data at speeds of up to 10 or 40 GB/s while providing up to 100 Watts of power to equipment. Unstructured cabling, or point to point cable systems, are also an option but can be less effective. They typically restrict airflow which may lead to cooling issues. On the other hand, structured cabling uses predefined standards, connection points and pathways to provide a reliable and efficient system. This is the best way to manage the cabling system and avoid costly mistakes.


Using the right labels on your cables and power systems is crucial to efficient management. It helps reduce downtime, troubleshooting time and maintenance costs. Labeling data center wire and power systems allows you to know exactly what is connected where. It also helps you track and trace problems. A data center’s power system uses a combination of AC (Alternating Current) and DC (Direct Current) electricity to supply alternating currents to IT equipment. It can also include a ground wire, which protects IT equipment from damage and prevents electromagnetic radiation from reaching the earth’s surface.


Data centers need a steady supply of electricity to power servers, lighting and cooling systems. They also need backup generators and battery banks to maintain operations in the event of a power outage. Keeping your equipment and backup power systems up to date and running properly will prevent downtime and optimize your data center. This includes testing your UPSes, automatic transfer switches and other power systems to ensure they can handle real-time loads. Mean time to repair (MTTR) and arc flash labeling are key parts of a data center’s maintenance strategy. Clever design will ensure that any necessary repairs can be carried out at the same time as the load is still running, to minimize disruption. A well-maintained data center will reduce energy costs and keep employees productive, while improving overall reliability. It will also help to ensure that faulty equipment doesn’t cause downtime and that your facility is protected from outside threats.
