Rising densities pose hidden risks for electricians
As power density increases, data centers are expected to transition to higher voltages, which will demand new safety precautions. However, even before operators raise voltage levels, they are already pushing densities higher. The resulting safety risks may not be sufficiently appreciated because many electricians assume risks are inherently lower in a low-voltage environment.
High-density data centers using GPUs for workloads such as AI training are expected to move from today's 415V AC and 480V AC power delivery to 800V DC. Leaving aside the benefits — reduced current, less copper and lower thermal losses — future Nvidia products such as Rubin Ultra, which is set to launch in 2027, are expected to ship in 800V racks, driving a voltage increase across the facility.
