need help with CSA codes in regards to GFCI/conduit requirements 120/240VAC breaker box

[emiller233]

I'm not familiar at all with the CSA code, so I'm looking for some guidance on how to properly install this setup. I'm not sure what does/doesn't need GFCI breakers, or if I can just get away with GFCI receptacles and use standard breakers for everything.

1. industrial application (Hydraulic power unit)
2. outdoor rated box, but will be mounted inside of a shipping container so the entire system is 'portable'
   1. Does this have to be done on conduit or LFMC? or can we run cables in a wire tray?
      1. any requirements for CSA that I don't know about? I'm assuming we have to use rainttight fittings if we use EMT?
      2. does the conduit/LFMC need to be CSA stamped or anything?
3. all single-phase 120VAC loads:
   1. 15A power to a cUL508A-rated industrial control panel (PLC and control stuff)
   2. 2500W immersion heater (hydraulic oil)
   3. 500W immersion heater (hydraulic oil)
   4. 500W immersion heater (hydraulic oil)
   5. (2) LED work lights mounted on the ceiling
   6. (2) 120VAC receptacles mounted on the interior walls
      1. are 'in-use' receptacle covers required? or can we use the spring-loaded door type?
