Project Review Service
UL Wire & Wiring Harness Project Review
MTTJ supports OEM cable assembly projects where customer-specified UL wire, cable, or wiring harness documentation requirements must be matched to the application, drawing, testing, and export documentation needs.
For a more accurate review, please provide a drawing, sample, clear product image, cable specifications, connector details, quantity, application environment, required testing, and target delivery schedule.

Specifications
Key specifications to define before quotation
Final requirements should come from customer drawings, specifications, test methods, acceptance criteria, and project documentation.
| Wire and cable documentation | Reviewed during RFQ and matched against customer requirements and supplied documentation |
|---|---|
| Rated voltage | Provided by customer specification or approved wire/cable documentation |
| Temperature rating | Confirmed from approved wire/cable documentation |
| Wire gauge | Defined by drawing, electrical requirements, and selected wire or cable construction |
| Documentation | Project documentation requirements reviewed before quotation and release |

FAQ
Common RFQ questions
Why does customer-specified wire or cable documentation matter?
Customer documentation can define insulation, jacket, voltage, temperature, construction, and intended use. MTTJ reviews the supplied requirement during RFQ rather than assuming it.
How are UL-related requirements reviewed?
UL-related requirements are reviewed by project against customer-supplied wire, cable, documentation, and target-market requirements. Buyers should provide applicable part numbers, standards, and documentation scope during RFQ.
