Low Voltage vs. 600v. Wire Raceway

You can always contact UL here. They may have a waiting list or queue that you must work through. You should also remember that this Wednesday is a national holiday.

And be aware, the speed at which UL tests and approves a new product that has never existed before is proportional to the inverse of the volume of the wheelbarrow containing $100 bills, squared.

Small wheelbarrow, long time, i.e. your grandchildren will benefit. Large wheelbarrow, shorter time. Gigantic overflowing wheelbarrow, quick.

Mtprofit,

My understanding is U/L tests a product using the testing requirements of a particular standard. The standards and the electrical codes co-exist, with a necessary interaction between the two. Example of this--the introduction of "Hospital Grade" receptacles. There was no standard for them and no code rule for their use. Hubbell developed a standard and products that would meet this standard, then presented it to U/L. They also presented the product as a recommended change to the text of the NEC. When these changes were all approved/incorporated, Hubbell had a valuable position as the first manufacturer with products that would meet the new standard and new requirements.

The NEC recognizes surface metal raceways and surface non-metallic raceways. I presume yours is intended to fit within the requirements of the latter. If you have not already done so, check these requirements and all referenced testing standards to see if your product fully falls within these, or if you need to propose new standards or requirements or code rules. As a plastic material, you also will need to consider the fire codes and possibly also the building codes. For an illustrative education on this, look at the controversy that surrounded the introduction of "Electrical Nonmetallic Tubing" or ENT--often called "Smurf tubing" because of its blue color (now also gray).

In addition to all this, you must meet the customer's requirements for durability, attractiveness, etc.
