Are my calculating the minimum size required correctly per NEC 314.28(2)? I have a pullbox with a 4 inch conduit entering and a 4" conduit exiting at the opposite wall (straight line). There is also a 1 inch conduit entering the bottom. So the 1" conduit is perpendicular to the 4" conduits. There is a splice within the box. A junction box, also known as an electrical box or splice box, is a container that houses electrical connections and splices. Its primary purpose is to provide a safe and secure environment for connecting and disconnecting wires, while also protecting the surrounding area from electrical shock and fire hazards.Step 4: Fold the spliced wires carefully back into the junction box. Fold the wire sets carefully into the junction box. Step 5: Always install a blank cover onto the junction box. Place a blank cover on the junction box and you're all done! You have now made a legal and accessible splice. I’ve seen a few posts here – including one on a question I asked yesterday – that say junction boxes and the like need to be accessible without tools. The “without tools” requirement is clear in the code definition of the term readily accessible, which applies to things like breakers and disconnects that require rapid access.But as far as I know it does not apply .

When conductors are spliced, the minimum distance from where the raceways enter to the opposite wall is six times the trade size of the largest raceway, plus the sum of the trade sizes of the . Typically a junction box either contains splices on the energized conductors (thus requiring that the box be individually bonded with a pigtail connected to the EGC), or the box is simply a pull-through point (thus not requiring the box to be bonded individually with a pigtail). .
