Features | 20A C20-to-C21 Power Cable for Network Devices That Require a Heavy-Gauge ConnectionThis heavy-duty cord features 12 AWG wire suitable for high power connections, making it a reliable solution for large server applications that require a higher-rated, heavier-gauge cable, including AI/machine-learning data centers. The four-foot ( 1.2 -meter) length helps reduce cable clutter by providing a tailor-made fit between the device and the PDU or UPS in a crowded rack enclosure. Recommended for High-Temperature EnvironmentsThe P035-004 can be used to connect a blade server, large router or network switch with a C22 inlet, usually found on high-powered, high-temperature (overall operating temperature maximum 105°C/221°F) equipment, to a PDU or UPS system.

It's an ideal upgrade to a power cord with improved temperature threshold for data center applications in which temperature control and fire safety are high priorities.
