The modeling design of an outdoor prop is of course important, because in the dark night, the light design makes this brand very easy to implant in the hearts of consumers. But pay attention to the design at the same time also want to consider the safety problem, because there is light, there is electricity, electricity must consider the safety problem. So what should we pay attention to when doing UL certification for outdoor Sign (props) and logo?
Outdoor Sign (props), UL certification, which standard is applicable?
Under normal circumstances, a complete outdoor Sign (props), logo, you need to be in accordance with the requirements of the finished product, based on UL 48 to do the whole machine UL certification.
Outdoor Sign (props), logo with power supply to do UL certification of the whole machine, what matters should be paid attention?
1) Because the outdoor Sign is connected to the mains power in the building system, it will be exported to North America and equipped with a junction box Junction Box when UL certification is made:
This Junction Box should be UL-certified. Note: If the customer is equipped with a power cord when shipping and makes electrical connection with strong electricity on site, 16AWG power cord should be equipped according to NEC regulations, and the length should be at least 153mm. If it is difficult to meet this requirement, it is better to ship without power cord and leave Knock Out for on-site electricians to connect.
A. The output wire of the power supply is wrapped in a metal Conduit to penetrate the wall to ensure that the electronic wire or power cord does not contact the wall;
B if the output wire of the power supply is not wrapped in a metal conduit when passing through the wall, and is separately discharged and not protected, it needs to be based on UL 48 select Class 2 cable, CL2, CL3, PLTC as the output line.
6) One more thing to remind is that the product is completed UL certification after completion, you need to purchase an anti-counterfeiting label from UL and paste it on the certified product.
