2 wire plug diagram - Metallic junction boxes and outlet bins have to be grounded. (Be aware: plastic electrical bins do now not require grounding.) I have to have set up the #10 green ground screw and 14 gauge floor cord whilst making the ground twine pigtail connections in advance, however i was focused on wiring the hole & switch and inadvertently ignored this critical step. The correction is straightforward with wire nut pigtail connections:.
I should put off it the vintage electric field due to the fact the ground cord is too short to make a proper pigtail connection. The electrician twisted and crimped the line- and load facet ground wires together, cut off ground wires within the field, then used a metallic crimp sleeve to connect the receptacle ground cord, that's a contravention of nec 300.14. According to nec 300.14, all conductors ought to expand at least 6 inches inside the container and as a minimum 3 inches beyond the field. In any other case, the building inspector will flag it and received’t signal-off on the electric permit.
How to cord an attic electric outlet and mild: a new junction container is stressed for the transfer managed electrical outlet for the attic light after casting off the old light switch and wiring. This assignment is continued from the exposed work cowl junction box project. Additionally see part 1 for the assignment introduction.
I trimmed the new (black) and white (neutral) wires to an same duration with the naked copper floor wire, stripped about three/four inch of insulation from the ends, then tightened the two screws at the nm cable clamp to at ease the cable to the junction container. The nm cable clamp additionally protects the nm-b 14/2 cable from nicks by means of the pointy metals edges of the junction field knockouts.
The plastic mild transfer electrical field is removed via inserting a massive screw driving force under the box to pry it off the two×4 framing. The container is held through nails and became easy to eliminate.
The road-aspect nm-b 14/2 wires are fed via the three/8″ nm cable clamp into the junction container, the box is located numerous inches lower on the 2×four framing by using attic stairway to offer at the least 6 inches of wires in the container, that is decided with the aid of the duration of the “brief” floor wire. The junction box bracket is mounted to the two×4 framing with pan-head wooden screws.
