NEMA 5-15P to 4-Hole "Plum Blossom" Style Female Power Cord
Standard Grounded US Input: Utilizes a NEMA 5-15P 3-prong male plug that provides a compliant 125V AC connection to standard North American wall outlets. This ensures safe, grounded power delivery from the facility infrastructure to the equipment power supply.
Injection-Molded Strain Relief: Both the wall plug and the custom 4-hole connector are fortified with heavy-duty ribbed strain relief transitions. This structural engineering absorbs kinetic pulling forces, preventing internal copper strand breakage when furniture or equipment is frequently moved.
Pure Copper Cable Core: Extruded with a commercial-grade SJT or SVT PVC jacket covering 100% pure copper conductors (such as 18AWG or 16AWG). This guarantees stable voltage delivery to high-torque electric motors, preventing dangerous overheating under continuous load.
OEM Configuration Ready: Total cable length, precise wire gauge, jacket rating, connector molding parameters, and compliance routing (UL/ETL) can be custom-manufactured to match your exact hardware specifications and commercial procurement checklist.
- Product Description
NEMA 5-15P to 4-Hole "Plum Blossom" Power Cord for Electric Motors and Specialized Equipment
The NEMA 5-15P to 4-Hole Female Power Cord is engineered to solve proprietary connection challenges for equipment manufacturers. By pairing a standard North American grounded wall plug with a specialized 4-pin "plum blossom" equipment connector, this cable delivers direct, reliable 125V AC power to linear actuators, electric recliners, and custom medical beds. Manufactured with pure copper conductors and structural strain relief, it ensures consistent motor performance while maintaining a verified 0.1% defect rate for bulk OEM procurement.
Why Choose Our NEMA 5-15P to 4-Hole Power Cord?
Standard IEC connectors like the C13 or C5 cannot mate with proprietary 4-pin motor power supplies. This cable eliminates the need for unstable aftermarket adapters by providing the exact physical interface your equipment requires right out of the box.
Custom 4-Pin Interface Matches Proprietary Hardware
The output side features a specific 4-hole layout. This interface is widely used in electric furniture motors, adjustable standing desks, and specific medical lift chairs. By molding this connector directly onto the cord, we provide a secure, locked-in fit that resists vibrating loose during mechanical operation.
NEMA 5-15P Grounded Plug for Safety Compliance
The input side utilizes a standard NEMA 5-15P 3-prong plug. This establishes a proper 125V AC connection to the facility's power grid, ensuring that the equipment power supply receives consistent voltage and, where applicable by internal wiring, maintains a protective earth ground path.
Molded Strain Relief Extends Cable Lifespan
Electric furniture and medical carts are frequently moved, which bends and pulls the power cord at sharp angles. We reinforce both the wall plug and the 4-pin connector with injection-molded, ribbed strain reliefs. This disperses kinetic energy along the PVC jacket, significantly reducing the risk of internal copper strand fracture.
Pure Copper Conductors Prevent Voltage Drop
Electric motors demand high inrush currents when activating. This cord is extruded with 100% pure copper conductors (typically 18AWG or 16AWG depending on load requirements) to handle these electrical spikes efficiently, preventing dangerous voltage drops and protecting the motor from premature failure.

Buyer's Insight: The 4-hole connector is not a universal standard like an IEC C5; dimensions can vary slightly between equipment manufacturers. Before confirming a bulk order, procurement teams must verify the exact pin diameter, pin spacing (pitch), and wiring diagram (which pins carry active/neutral/control signals) against their specific motor power supply. Matching the wire gauge to the load current is also strictly required for UL/ETL compliance.
Professional Applications You Can Trust
For electric recliners and lift chairs, the power brick often sits under the seat mechanism. This cord plugs directly into the proprietary 4-pin port on the motor housing or external power supply, providing a secure connection that won't easily disconnect when the chair is extended or retracted.
In medical and rehabilitative care settings, adjustable beds require specific power connectors to prevent accidental swapping with incompatible high-voltage cables. The unique 4-hole interface ensures only the correct, rated power cord is used for the bed's linear actuators.
For custom AV and IT equipment, manufacturers sometimes use 4-pin layouts for specific power delivery requirements. This cable allows them to supply standard US wall power to their proprietary internal components cleanly and professionally.
Advanced Safety Features
The NEMA 5-15P plug features a grounding pin. Buyers must consult their equipment's schematic to determine if the 4-pin connector utilizes the ground wire, or if it is strictly passing line/neutral/control signals. Proper grounding routing is critical for avoiding electrical compliance risks.
We strictly calculate the AWG sizing based on your equipment's continuous and peak load currents. Supplying a heavy-duty electric motor requires adequate copper mass to avoid thermal overload within the PVC jacket.
The SJT/SVT jacket provides excellent insulation against typical indoor abrasion, such as rubbing against metal chair frames or being pinched under furniture legs. It isolates the high-voltage copper safely away from operators.
Manufacturing Excellence
Leveraging 17 years of specialized OEM cable manufacturing, we provide precise custom molding for non-standard connectors. Every power cord is subjected to 100% automated continuity testing, polarity checks, and Hi-Pot dielectric testing. We ensure exact pin matching and support strict UL/ETL certification routing for the North American market.
Frequently Asked Questions
Q: How do I ensure this 4-hole connector fits my equipment?
A: Because 4-pin layouts can be proprietary, we strongly recommend providing a technical drawing of your equipment's male inlet or sending a physical sample of the original cord. Our engineers will verify the exact pin spacing and diameter before production.
Q: What wire gauge should I specify for an electric recliner motor?
A: This depends on the motor's amperage rating. 18AWG is typically sufficient for standard consumer recliners (up to 10A), while 16AWG may be required for heavy-duty medical lift beds. We will help match the AWG to your load requirements to maintain safety compliance.
Q: What is the sample dispatch timeline for this specific connector?
A: If your equipment uses our standard 4-hole mold, our sample dispatch timeline is typically 3-5 working days. If a custom mold adjustment is required for your specific pin spacing, CAD design and tooling will take slightly longer.
Q: What information is needed for a quotation?
A: Please provide the total cord length, required wire gauge, a photo or drawing of the 4-pin equipment inlet, target UL/ETL certification needs, order quantity, and packaging requirements.
