Server power cord types explained: C13/C14 for standard 1U servers, C19/C20 for high-draw equipment, and locking IEC when accidental pull-out isn't an option. Includes selection chart and PDU matching guide.

C19 and C20 are the 16A/250V IEC mating pair for high-draw servers, blade chassis, and large UPS units — one tier above C13/C14. Learn which inlet your equipment has and when to step up.

 C13 and C14 are a mating pair under IEC 60320-1: the C13 female coupler is on the cord; the C14 inlet is built into the server or PDU. Learn the ratings, when to step up to C19/C20, and what to check before ordering.

The NEMA 5-15P is the standard 15A/125V three-prong power plug in North America. Learn what the ratings mean, how the polarized pinout works, and when to step up to a 20A connector.

Cat5e vs Cat6 explained for installers and IT buyers: the real bandwidth and PoE gap, 10GbE distance limits, and which Ethernet cable to run for each job.

 An RJ45 wiring diagram with the full T568A vs T568B color code, pin-to-pair mapping, and a step-by-step guide to crimping plugs and punching down keystone jacks — plus the cross-wiring mistakes that fail Cat6 links

CCA cable — copper-clad aluminum — looks identical to pure copper Cat6 on the outside. The difference shows up on certification tests, under PoE load, and after years in the wall. This guide covers what CCA is, why it fails standards-compliant installations, and how to verify conductor material before the cable goes in.
