From UL1007 Specification Confusion to a Successful UL1569 10AWG Solution
How Zhengfeng Wire Helped a Dutch Customer Solve Wire Selection, Sampling, Quality Testing, and Custom Packaging Challenges？
When a European equipment manufacturer was looking for a reliable supplier of 10 AWG UL hook-up wire, they initially contacted Guangdong Zhengfeng Wire & Cable Technology Co., Ltd. through Google.
The customer's initial requirement was UL1007 10AWG wire. However, after reviewing the requirement carefully, our technical team identified an important issue: UL1007 does not cover 10 AWG as a standard size, while UL1569 is a suitable UL style for 10 AWG hook-up wire applications.
Instead of simply telling the customer that the requested specification was unavailable, our team investigated the requirement further, checked the relevant UL style information, and recommended UL1569 10AWG as a practical alternative.
This became the beginning of a successful cooperation—from technical clarification and sample development to product testing, mass production, and customized packaging.
The customer found Zhengfeng Wire through Google and contacted our team with a requirement for UL1007 10AWG electrical wire.
After reviewing the specification, our sales and technical team immediately noticed that the requested combination of UL style and conductor size needed clarification.
Rather than treating the inquiry as a simple product quotation, we first focused on understanding exactly what the customer needed.
The customer later clarified that the wire they were currently using was referred to as UL1007 / UL1569, which created some confusion regarding the applicable UL style.
To help the customer make an informed decision, we provided the relevant UL Style Pages for reference and explained the distinction between the two styles.
Based on the applicable UL requirements, 10 AWG is not a standard size under UL1007, while UL1569 can cover 10 AWG applications.
Therefore, we recommended UL1569 10AWG wire rather than simply producing a product with an incorrect or misleading UL style designation.
Why This Matters to Engineers and Purchasing Teams？
UL hook-up wire styles can look similar from a purchasing perspective, but the applicable construction, voltage rating, temperature rating, conductor range, insulation system, and certification requirements need to be evaluated carefully.
For OEMs and equipment manufacturers, selecting the correct UL Style is important because the wire must match the electrical, mechanical, environmental, and compliance requirements of the final equipment.
This is why our team does not only focus on supplying wire—we also help customers verify specifications and identify suitable UL wire solutions before production.
During the technical discussion, we explained to the customer that Zhengfeng Wire could manufacture the required UL1569 10AWG wire, but our capability went beyond manufacturing.
Our team has extensive experience working with UL-certified wire products and understands the importance of matching customer requirements with the corresponding UL Style, conductor construction, insulation material, voltage rating, temperature rating, dimensions, printing requirements, and applicable certification information.
To help the customer evaluate the solution, we provided:
This gave the customer a clearer understanding of why UL1569 10AWG was a more appropriate solution for their requirement.
Most importantly, we did not stop at the specification discussion.
We asked the customer about their actual application, current wire supplier, production process, existing wire performance, and the problems they were experiencing.
This allowed us to move from simply supplying a product to providing an application-oriented wire solution.
The customer shared details about their current wire usage and explained the difficulties they had experienced with their existing supplier.
For a wire used inside electrical equipment, simply meeting a nominal AWG size is not enough.
Depending on the application, the customer may also need to consider:
Our team reviewed these requirements together with the customer's actual application.
Instead of pushing a standard product, we evaluated the customer's problems and discussed how the proposed UL1569 10AWG wire could better fit their equipment and manufacturing process.
The customer was highly impressed by the technical communication and professionalism of our team.As a result, the customer quickly decided to place a sample order.
Once the sample order was confirmed, our production team immediately arranged the sampling process.
We understood that for an overseas customer, sample lead time can directly affect the qualification schedule and subsequent purchasing decision.
Therefore, we prioritized the sample production and coordinated closely with our production department and logistics partner.
The UL1569 10AWG samples were manufactured and shipped as quickly as possible.
The customer received the samples shortly afterward and expressed strong satisfaction with our response speed and delivery efficiency.
But for us, shipping the sample was only the beginning.
We continued communicating with the customer during the testing period and remained available to answer technical questions and provide additional information whenever required.
After completing their internal testing, the customer shared excellent feedback.
The UL1569 10AWG wire supplied by Zhengfeng Wire performed very well during their evaluation.
For an equipment manufacturer, these details are important because wire quality directly affects assembly efficiency, electrical reliability, product consistency, and long-term equipment performance.
The customer therefore confirmed that our UL1569 10AWG wire was suitable for their application.
Soon after the successful sample evaluation, they placed the formal production order with Zhengfeng Wire.
The product qualification was successfully completed, but the project was not yet finished.The customer had a special requirement for the packaging: they wanted the wire to be packed in a custom-designed carton box according to their own packaging concept.
At first glance, this might appear to be a simple packaging request.In reality, it presented a significant challenge.The dimensions and structural information provided by the customer were incomplete.When we contacted several carton manufacturers, many suppliers told us that they needed additional information such as:
Some suppliers even required a physical sample before they were willing to develop a prototype.Meanwhile, the customer's requested delivery schedule was approaching.
We could have told the customer that the packaging requirements were too complicated.
Instead, we decided to find a solution.
Our team continued communicating with the customer to understand the packaging concept in greater detail.
At the same time, we continued searching for a carton manufacturer willing to develop the packaging together with us.
After contacting multiple suppliers, we finally found a packaging partner willing to take on the project despite the incomplete initial information.
The first carton prototype was produced.
However, after testing the actual wire inside the carton, we discovered that the first version was not ideal.There were still opportunities to improve the dimensions, internal fit, appearance, and space utilization.At this point, the delivery schedule had already become tight.We knew that simply exchanging emails would not be efficient enough.
So our team took the actual wire directly to the carton factory and worked with the packaging engineers on-site.
At the carton factory, our team reviewed the packaging structure together with the supplier.We evaluated the actual wire dimensions and packaging requirements and discussed how to optimize the carton structure.The goal was not simply to make the carton fit the product.
We wanted to achieve several objectives at the same time:
Better appearance + safer protection + efficient space utilization + lower unnecessary packaging costs.
The carton structure was adjusted according to the actual product.During this process, Zhengfeng Wire maintained real-time communication with the customer.We continuously shared:
This allowed the customer to clearly understand what was happening at every stage.
For international customers, transparency is particularly important.
Even when unexpected problems occur, customers feel more confident when they know that their supplier is actively solving the problem rather than waiting until the last moment to report it.
After several rounds of communication and adjustment, the second carton prototype was completed.This version was significantly more suitable for the customer's requirements.
The customized carton consisted of three structural components, and the selected carton material was sufficiently rigid to provide the required protection.However, the stronger material also meant that assembly required additional time and careful handling.
At this stage, the wire itself had already been produced and was ready for shipment.
The remaining challenge was completing the final packaging within the customer's required schedule.
To avoid unnecessary delays, Zhengfeng Wire's employees worked together to complete the packaging process.Rather than treating packaging as a separate task, our team worked as one project group.Everyone actively responded to the customer's delivery requirements.The three-part cartons were assembled, the UL1569 10AWG wire was carefully packed, and the finished cartons were checked before shipment.The entire process was completed as quickly as possible.
Once the final packaging was completed, we immediately shared photos and project updates with the customer.The customer's response was simple but meaningful:
A thumbs-up for Zhengfeng's speed, quality, and teamwork.
This project was not simply about selling a roll of electrical wire.
It demonstrated how a professional wire manufacturer can support customers throughout the entire procurement and product-development process.
When the customer requested UL1007 10AWG, we identified the specification issue and helped them understand why UL1569 was a more appropriate UL Style for the required 10 AWG application.
We did not recommend a product based only on the AWG number.
We discussed the customer's actual application and production requirements before proposing a solution.
The sample order was prioritized so that the customer could quickly conduct product testing and qualification.
The customer's evaluation confirmed that the wire's appearance, printing, dimensions, and tested electrical performance met their expectations.
When the customer required a non-standard carton structure, our team continued searching for a suitable packaging partner and participated directly in the optimization process.
Sales, technical, production, logistics, and packaging suppliers worked together to keep the project moving.
We kept the customer informed throughout the project instead of waiting until the final delivery to provide an update.
