Rack-Ready L5-20P to C19 Locking Cord

This 6 ft extension cord connects a NEMA L5-20P twist-lock plug to a C19 inlet for servers, PDUs and rack-mounted equipment. The locking mechanism prevents accidental disconnection under vibration or cable management shifts. It is built for data-centre and server-room circuits that require a secured 20 A connection. Buyers who need a non-locking straight-blade plug or a different inlet type cannot use this cord.

Plug-In Installation with Twist-Lock Action

Insert the L5-20P into a matching locking receptacle and rotate until it clicks; the cord seats without tools. The only common issue is attempting to force the plug into a non-locking 5-20R outlet, which will not accept the twist-lock blades. The 12 AWG SJT jacket is stiff, so allow slack for routing in tight cable trays. No software or driver steps are involved.

Sustained 20 A Load on 12 AWG Copper

The three-conductor copper cable is rated 20 A at 125 V with a 105 °C / 300 V SJT insulation rating. Under continuous 20 A draw the conductors run warmer than lighter-gauge cords but remain within the UL-listed and CSA-certified limits (file E210037). The cord is not suited for loads above 20 A or voltages above 125 V.

Questions about this item

How do I confirm the twist-lock L5-20P is fully seated after plugging it into the PDU?

Turn the plug clockwise until it clicks and the locking tabs engage; the cord should resist a firm pull without disconnecting, showing the 20 A / 125 V circuit is live.

What comes in the package and is any extra hardware required?

The box contains one 6 ft black SJT 12 AWG cord with a NEMA L5-20P plug on one end and an IEC C19 connector on the other; no additional adapters or tools are needed for rack or PDU use.

Why choose the 12 AWG 20 A version instead of a thinner gauge?

The 12 AWG construction is rated for 20 A continuous at 125 V, matching L5-20P outlets and heavy-duty server or PDU loads, whereas 14 AWG stops at 15 A and 16 AWG at 13 A.
