TLDR: use UL, CSA or ETL listed North American gear that is labeled for a range of voltages inclusive of yours. For instance North America .
Although the wires are encased in a PVC conduit, the line is just laying on the ground. My understanding is that NEC requires the line be covered by at least .

I am providing lighting and power for a pergola. A PVC conduit comes out of the ground about 18" from one of the posts, so I need to bridge . Light fixtures in damp areas (protected by an overhanging eave or roof) must be listed for damp locations. Surface-mounted electrical boxes for all electrical fixtures must be raintight/weatherproof. Exterior light fixtures do not . Understand the different types of electrical conduit, including common types, rigid vs. flexible tubing, grounding boxes, what wiring to use, and why. You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means .
Generally speaking, though, the National Electrical Code allows for three means of running underground circuits: Laying UF (underground feeder) cable directly into the ground. There is no need to run a wire from the box to the receptacle ground terminal as the self grounding feature makes that connection. Recently saw a YouTube video by a individual .
You will rarely get in trouble for bonding all of your metal parts since it’s required in nearly every installation, and I’m surprised you haven’t been asked to ground/bond metal junction boxes before, even if they are just pull-through . We had an underground wire pull, across an area that was to be a lay down yard. There were 4 in ground concrete boxes spaced about 200 ft apart to get power to a "shack" .Although the wires are encased in a PVC conduit, the line is just laying on the ground. My understanding is that NEC requires the line be covered by at least 8 inches of dirt. My contractor says the line is NEC compliant. IMO, the way the code reads, you either have to bury it or secure it if above ground. Then you get into "subject to physical damage" thing which would require schedule 80. My gut says you shouldn't route conduit directly on the ground.
I am providing lighting and power for a pergola. A PVC conduit comes out of the ground about 18" from one of the posts, so I need to bridge that small gap. NEC table 300.5 covers burial depth, and for RMC* I can get by with only 6" of burial depth. Light fixtures in damp areas (protected by an overhanging eave or roof) must be listed for damp locations. Surface-mounted electrical boxes for all electrical fixtures must be raintight/weatherproof. Exterior light fixtures do not require GFCI protection.
Understand the different types of electrical conduit, including common types, rigid vs. flexible tubing, grounding boxes, what wiring to use, and why. You don't need a wire to ground the switch, the mounting screws satisfy the requirement when used with metal boxes, and there is an exception that allows you to not satisfy grounding requirements if no grounding means exists for replacement switches. Generally speaking, though, the National Electrical Code allows for three means of running underground circuits: Laying UF (underground feeder) cable directly into the ground.
There is no need to run a wire from the box to the receptacle ground terminal as the self grounding feature makes that connection. Recently saw a YouTube video by a individual who claimed to be a licensed electrician who ran the cable ground wire to the receptacle ground terminal and relied on the self grounding feature to ground the box.

We had an underground wire pull, across an area that was to be a lay down yard. There were 4 in ground concrete boxes spaced about 200 ft apart to get power to a "shack" that was the shipping/receiving office and scale house. The conduits had been blown clean when the pig was blown through. We pulled in 4 #2's and 1#6, easy pull.Although the wires are encased in a PVC conduit, the line is just laying on the ground.
