NEMA 10-30P to 10-30R Heavy-Duty Extension Cord

Typical NEMA 10-30 configurations carry 30A at 125/250V AC using two hot conductors and one neutral conductor. A 10AWG, 3-conductor cable is a common option for this current class, while the final wire specification, cable jacket, length, and assembly rating must be confirmed for the intended application.

Why Choose Our NEMA 10-30 Extension Cord?

This cable is intended for appliance suppliers, electrical distributors, and project buyers who need a clearly identified NEMA 10-30 male-to-female extension solution.

Matching NEMA 10-30 Interfaces

The NEMA 10-30P plug connects to a compatible NEMA 10-30R wall receptacle. The cable-mounted 10-30R connector accepts a matching 10-30P appliance plug, extending the connection without changing the interface type.

Heavy-Duty 30A Configuration

NEMA 10-30 is commonly associated with 30A, 125/250V AC applications. Appropriate conductor size and cable construction help buyers match the assembly to the required current and extension length.

Molded Ends with Strain Relief

The molded plug and receptacle bodies help maintain a consistent cable termination. Integrated strain relief supports the cable at common bending points during installation and appliance positioning.

Configurable for B2B Orders

Cable length, wire gauge, jacket type, molded shape, connector orientation, labeling, branding, and packaging can be configured according to the buyer's technical and distribution requirements.

Complete Product Specifications

Buyer's Insight: NEMA 10-30 and NEMA 14-30 are not interchangeable. NEMA 10-30 uses two hot conductors and one neutral conductor without a separate equipment ground, while NEMA 14-30 uses a four-wire arrangement with a dedicated grounding conductor. Confirm the wall receptacle, appliance plug, wiring requirement, and applicable electrical rules before ordering.

Professional Applications You Can Trust

For compatible legacy electric dryer installations, this extension cord increases the distance between an existing NEMA 10-30 wall receptacle and an appliance fitted with a NEMA 10-30P plug. Multiple length options help buyers accommodate different laundry-room layouts.

For appliance distributors and replacement-cord suppliers, the clearly matched 10-30P and 10-30R interfaces reduce the risk of ordering an incompatible NEMA configuration. The molded construction also supports consistent presentation in packaged cable products.

For OEM and project procurement, cable length, wire gauge, jacket construction, molded shape, and packaging can be aligned with the intended load, installation environment, and sales channel.

Advanced Safety Features

The molded plug and receptacle bodies enclose the cable terminations, while strain relief at both ends helps reduce concentrated bending where the cable enters each connector.

This three-wire NEMA 10-30 configuration does not provide a separate equipment-grounding conductor. It should only be used with compatible installations and equipment for which this interface is permitted; the neutral conductor must not be described as a dedicated equipment ground.

The final conductor size, cable jacket, assembly rating, and certification direction should be confirmed according to cable length, connected load, installation conditions, and destination-market requirements.

Manufacturing Excellence

This NEMA 10-30P to 10-30R extension cord can be configured for B2B and OEM purchasing requirements. Buyers can confirm cable length, conductor gauge, jacket type, molded connector shape, cable marking, label, and packaging before production.

Frequently Asked Questions

Q: What connectors are fitted to this extension cord?

A: The cable has a NEMA 10-30P male plug on one end and a NEMA 10-30R female receptacle on the other end.

Q: Does this NEMA 10-30 cable include a grounding conductor?

A: No. NEMA 10-30 is a three-conductor configuration with two hot conductors and one neutral conductor. It does not include a separate equipment-grounding conductor.

Q: Can it replace a NEMA 14-30 extension cord?

A: No. NEMA 10-30 and NEMA 14-30 use different plug patterns and wiring arrangements. The cable must match both the power receptacle and the connected equipment.

Q: Can the length and wire gauge be customized?

A: Yes. Common lengths include 1ft, 1.5ft, 2ft, 3ft, 5ft, and 10ft. Wire gauge, cable type, molded shape, labeling, and packaging can also be configured according to the required rating and order specification.
