Server Power Extension

This 15 ft cord carries a NEMA L5-30P plug to a NEMA L5-30R receptacle, rated for 30 A at 125 V. The 10 AWG SJT conductors and fully moulded ends are built for continuous high-current service in rack environments. Both connectors lock to prevent accidental disconnection under vibration. UL and cUL listings confirm compliance with North American safety standards.

Suited For Rack Gear

It serves administrators who need to extend a locking 30 A feed to a server, PDU or UPS without reducing ampacity. The heavy-gauge cable handles the full rated load over the full length. Installations that require a different locking geometry, a higher voltage rating or a non-locking straight-blade connector will not mate with this cord.

Decisive Spec: NEMA L5-30 Locking Pair

The combination of a NEMA L5-30P plug and a NEMA L5-30R receptacle is the single attribute that determines fit. Only equipment presenting the matching L5-30 inlet and outlet can use this extension; all other connector types are physically incompatible.

Questions about this item

Will the 10 AWG SJT cable and NEMA L5-30 locking connectors fit inside a standard 19-inch server rack cable manager?

The 15 ft cord uses 10 AWG SJT conductors and fully moulded NEMA L5-30P and L5-30R locking plugs; allow enough vertical space for the thick jacket and the locking collar depth when routing through rack managers.

What is the correct way to engage the NEMA L5-30 locking connectors so they do not come loose under vibration?

Align the blades with the L5-30 receptacle, push fully in, then twist the plug clockwise until the locking ring clicks; the step often missed is the final twist that seats the locking mechanism.

How often should the 10 AWG conductors and moulded ends be inspected for wear in a 30 A 125 V server deployment?

Inspect the cord visually every 6 to 12 months for jacket cuts, discolouration at the moulded ends, or loose locking collars; replace immediately if any damage is found.
