Power Adapter Cords
Power adapters are used to enable equipment with disparate input/output receptacles to work together. I.e. use a power adapter to connect an IEC C14 power plug to a NEMA 5-15 receptacle.
Power Jumper Cables
Jumpers are used to connect two pieces of equipment without cluttering up the cable arrangement; Jumper cables provide a power interconnect between the active component, such as a server, and a power distribution device such as a power distribution unit (PDU), an uninterruptible power supply (UPS), or an extension strip.
Power Cord Splitters
Splitters are used to add extra equipment to a UPS or PDU without using up more outlets. I.e. a splitter cable can be used to split (1) NEMA L21-30 plug into (3) NEMA L5-30 receptacles.
