Power Wiring Harness Assembly Manufacturing

As a contract power wiring harness assembly manufacturer, OurPCB builds finished power interconnects from standard AC cords to high-current DC cable assemblies. Our cable assembly work supports customer-specified materials, drawings, labels, and test requirements for global markets with current ratings up to 500A and voltage ratings exceeding 1000V.

We manufacture AC power cords with country-specific plugs for North America (NEMA), Europe (CEE/Schuko), UK (BS1363), Australia, China, and other regions. IEC connector options include C13/C14, C19/C20, and other standard configurations. We build to the drawing, BOM, labeling rules, and approved file requirements supplied for the target market.

DC power applications include battery cables for EV and solar installations, PDU cables for data centers, and motor power cables for industrial machinery. Our high-voltage harness expertise extends to renewable energy systems and electric vehicle charging infrastructure.

Wire gauges from 18 AWG to 4/0 AWG accommodate any current requirement. Connector options include Anderson PowerPole, terminal lugs, and custom terminations. Jacket materials include PVC, TPE, rubber, and silicone for temperature and environmental requirements.

Every power cable or power wiring harness undergoes 100% electrical testing with hi-pot testing available for safety-critical applications. Rapid prototyping and flexible ordering support projects at every stage. Contact us for power wiring harness assembly quotes.

Common Questions
