Junction box wiring diagram - I must get rid of it the antique electric box due to the fact the ground wire is too brief to make a proper pigtail connection. The electrician twisted and crimped the line- and load side ground wires together, reduce off ground wires within the box, then used a metallic crimp sleeve to attach the receptacle floor twine, which is a contravention of nec 300.14. In step with nec 300.14, all conductors ought to expand at the least 6 inches in the container and as a minimum three inches beyond the field. Otherwise, the building inspector will flag it and gained’t sign-off on the electrical allow. The plastic light switch electric container is eliminated by way of inserting a huge screw driving force below the box to pry it off the 2×4 framing. The container is held by nails and become easy to dispose of.
Steel junction bins and outlet bins ought to be grounded. (Notice: plastic electric packing containers do now not require grounding.) I should have installed the #10 green floor screw and 14 gauge floor twine when making the ground cord pigtail connections earlier, however i used to be centered on wiring the outlet & switch and inadvertently ignored this vital step. The correction is straightforward with twine nut pigtail connections:. The way to cord an attic electric outlet and mild: a brand new junction container is stressed out for the switch managed electric outlet for the attic light after doing away with the vintage mild transfer and wiring. This project is continued from the exposed paintings cover junction container task. Additionally see element 1 for the mission introduction.
I trimmed the recent (black) and white (impartial) wires to an equal duration with the naked copper floor twine, stripped approximately three/four inch of insulation from the ends, then tightened the two screws on the nm cable clamp to comfortable the cable to the junction box. The nm cable clamp also protects the nm-b 14/2 cable from nicks through the sharp metals edges of the junction box knockouts. The line-aspect nm-b 14/2 wires are fed thru the three/eight″ nm cable clamp into the junction field, the field is placed several inches lower on the 2×4 framing by attic stairway to provide at the least 6 inches of wires within the field, which is determined by means of the duration of the “short” ground wire. The junction box bracket is fastened to the two×4 framing with pan-head wood screws.
