Hello,
We are building display cabinets for a retail store in Los Angeles and had a few questions on LED strip lighting. Each cabinet would contain the following items:
Meanwell HRPG-450-12 power supply 37.5a @ 12v

24pcs x 5m LED 3528 strip light
My questions are the following:
1. The power supply would be mounted on the top of the cabinet which is 8 feet from the ground. Are we required to use a NEMA 1 type enclosure for it at this height? I read that if over 7 feet, it is not required. Can the terminals of the power supply be openly accessible at this height? An example of the NEMA enclosure is here https://www.trcelectronics.com/View/TRC/TRC-E-HRP300450600.shtml
2. Do the LED strip lights need to be listed? What documentation may the inspector expect?
3. We plan on running 4 cabinets per circuit at 220v (9.6 amps total). We would like to wire the cabinets with a NEMA 6-15p plug coming off the top of them, going to the ceiling. How would we direct the on-site installing electrician to prep the ceiling? Can they hang an SOOW type cord from a junction box on the ceiling above the display case with a 6-15R type plug? So basically, the SOOW cord hangs off the ceiling to the outlet, around 8 feet off the ground. And the case plugs in to the outlet.
4. With above spec'd, should there be a strain relief or something for the cord? I'm guessing the ceilings are at 12-20 feet tall.
5. Will the electrical inspector wait to see the entire display cases installed and plugged in or would they check off a final with just the outlets in place?
Thanks in advance for any advice!
