How many j boxes?

[Ithinkimstillhere]

I have some under bench led lighting. 3"x8" flush mounted every 8 feet for about 200 feet in a concrete wall. 277V and I can use just one 20A circuit for them all.how often do I need a j box...do I even need them since I am daisy chaining the fixtures in the concrete wall and there are no splices?

What wiring method you using? (PVC) Are the luminairs marked with a max size and number of conductors?

We are using PVC. and I'm not sure about them being marked by max conductors.

Not to be too picky, but how is 277v and 20 amps showing up in the "Low Voltage and Limited Energy" forum?

Well strictly speaking 277 volt is low voltage.

I would think you would only need the j-boxes at each light fixture, unless something unusual about your set up.

Someone asked my bosses dad if he had any low-voltage experience.

"Sure. I have worked on 480V motors and gear as long as I have been an electrician", was his answer.
