Hi guys, I have a question regarding what conduit, size of conduit, and junction box I should be looking into. Currently have 11.55 kW, 30 panels, 3 strings. Using 8 THWN AWG wire so I believe that makes 6 wires going into a junction box, not including the grounds, of which I think there's 5.The light fixture has been buzzing since we moved in the place. This is why I've disconnected it and put a solar powered light next to it for now. I'd like to move the box inside and replace the light fixture. My question is do I just cut a circular hole in the wall and mount a normal junction box inside? Or do I need a weather-proof junction box?NEC 314.23 requires all junction boxes to be securely and rigidly supported. But is it truly a junction box? . If it were to be considered a non-integral junction box then it would be against code to mount that box in the ceiling when it is only accessible by removing a light fixture (2020). I am new here so bare with me. I had an inspection today for a ground mount PV system. We failed because we did not use An irreversible splice inside the junction box. We have a continuous Bare copper run connecting the modules, rails, the structure and two ground rods located at the array that eventually runs into a junction box.
Quick question. Is there a minimum mounting height for installing a junction box? To my knowledge, there isn't one. I've heard of 18" to avoid snow/flooding, but I think that was more a general ease of access. Use: Texas (checked TxDOT requirements and there are none), outside, on concrete column, for use of aesthetic lighting along sidewalk. I'm trying to design a junction box and I am having difficulty interpreting NEC 314.71 for the sizing requirements. I have a straight pull through the junction box and it states that the length of the box needs to be 48 times the outside diameter, over sheath, of the largest shielded conductor or cable. Disconnecting means and wiring methods for solar installations must meet requirements specific to solar photovoltaic systems. . National Electrical Code. Code Basics. NEC Requirements for Solar — Part 3. Aug. 19, 2024 . The NEC allows you to locate junction, pull, and outlet boxes behind PV modules [Sec. 690.34]. .
NEC 314.29 Junction Boxes for Non-Hazardous Location. The regulations outlined in the NEC 314.29 emphasize that the junction boxes must be easily reachable.
