Appliance Wire Harnesses for Home and Industrial Equipment
Appliance wire harnesses provide organized routing of electrical wire and cable, ensure safe connections across everyday and industrial appliances and reduce assembly time, improve reliability and allow OEMs to maintain consistent quality standards.
The global appliance market is projected to exceed USD 600 billion by 2030 according to Grand View Research, driving demand for advanced wiring and custom wire harness solutions. WellPCB supports this growth by delivering precision engineered, tested and certified harnesses tailored to modern consumer electronics and heavy duty industrial applications.
WellPCB manufactures wire harness products for appliances using UL-certified electrical wire, flame retardant insulation and Molex or Amphenol connectors.
Each custom wire harness manufacturer build is validated with 100% continuity checks, insulation resistance measurements and pull-force testing. We provide wire harness assemblies that reduce in-field wiring errors and support both prototype evaluation and OEM scale deployment.
Appliance Wire Harness Manufacturer Capabilities
Automated machines cut and strip wire and cable with ±0.1 mm accuracy across gauges from 10 AWG to 30 AWG.
This precision guarantees consistent harness lengths, clean terminations and reduced rework during appliance assembly.
We apply monitored crimp forces between 20 to 200 N, ensuring every terminal connection meets IPC/WHMA-A-620 workmanship standards.
Harnesses integrate UL-listed connectors from leading suppliers such as Molex and Amphenol for high current appliance wire harnesses.
Injection overmolding enhances durability by sealing out moisture, oil and dust. Jackets are manufactured from PVC or XLPE compounds rated for operating temperatures between -40°C and +125°C.
These insulation systems extend the service life of wire harness products in home appliances and industrial environments.
We design custom wire harness solutions for HVAC units, induction cooktops and commercial appliances rated up to 600 V AC.
Clearances and creepage distances comply with ISO, UL and RoHS international quality standards.
Our engineering team can deliver prototype builds within 3 weeks, enabling rapid validation of new appliance models.
This service allows OEMs to evaluate form, fit and electrical integrity before scaling to volume production.
With automated assembly lines, we support production from 50 units to more than 100,000 harnesses.
Our flexible approach accommodates both custom batches and long term OEM contracts, backed by advanced manufacturing processes.
Every harness undergoes 100% electrical continuity checks, hipot testing up to 3 kV and pull-force validation.
For long term durability, we perform salt spray corrosion tests on terminals and connectors, ensuring reliable performance across industrial applications and consumer products.
We provide wire ID systems with barcoding, heat-shrink labeling and color coded conductors.
Packaging can be customized for streamlined assembly line use, supporting equipment manufacturers that require organized, ready-to-install wire harness assemblies.

Appliance Wire Harness Manufacturers Client Feedback
As an R&D manager, I have had an outstanding experience working with WELL-PCB. For many years, our company has entrusted them with the production, assembly, and programming of the boards developed in our R&D unit, and they have consistently exceeded our expectations.
Hamid Reza Moshayedi
R&D Manager
Their work is very impressively perfect. Today, when they check our company PCB board after assemble. They found a fake short point which many engineers has never found in the past years. But that is just designed so. The PCB board quality is excellent. Their service is also excellent.
MikeZ
My friend introduced WellPCB to me, the first try, a little look forward to. I ordered a 47*72 10ps PCB, and I can’t wait to receive my PCB. So I used expedited service and received my PCB in three days. I tested and soldered the PCB, Quality is really good, silkscreen, plating also great.
