12 Gauge Wire, Fill - There is an exception below the conductor-fill provision that relates to luminaire (fixture) conductors. An device-grounding conductor or four or fewer luminaire (fixture) wires smaller than 14 awg, or both, entering a box from a domed luminaire (fixture) or similar cover and terminating inside that field, may be not noted from container-fill calculations. Beneath sure situations, up to four luminaire (fixture) conductors and one device-grounding conductor can be set up but not counted inside the box-fill calculation. The conductors need to be 16 awg or smaller and should input the container from a domed luminaire (fixture) or comparable canopy. (See discern 7.).
A conductor, no part of which leaves the box, shall not remember. [314.16(b)(1)] on the grounds that pigtails do now not depart the field, they're no longer counted in container-fill calculations. Likewise, equipment-bonding jumpers are not counted because they do no longer go away the field. (See discern 6.) Be aware that system-bonding jumpers are not the same as device-grounding conductors. Gadget-grounding conductors enter the field thru a raceway or cable and therefore need to depend in field-fill calculations.
Sometimes conductors enter and exit a field with out being reduce or spliced. Every conductor that passes via a box with out splice or termination counts as one conductor. [314.16(b)(1)] a conductor that runs via a box uncut, within the equal manner that larger conductors are established in pull boxes, counts as best one conductor. For instance, six 12 awg conductors are jogging through a 4-inch square metal container that is 1 1/2 inches deep. For the reason that conductors are without splice or termination, handiest six conductors are counted. Table 314.Sixteen(a) allows a maximum of 9 12 awg conductors in a 4-inch rectangular box this is 1 1/2 inches deep. This set up is code compliant. (See discern 3.). Caution is advised while cutting and splicing formerly unbroken conductors within a field. This method should, depending at the container length and the range of conductors, violate the field-fill necessities. For instance, a four-inch square steel box that is 11/2 inches deep includes six unbroken 12 awg conductors. If all of the conductors are cut and spliced, the number of conductors on this field could double. Since the maximum range of 12 awg conductors authorized in a 4-inch rectangular container this is 1 1/2 inches deep is 9, this set up now violates the field-fill requirements. (See parent 4.) If the conductors ought to be cut and spliced, one feasible answer, area permitting, is to feature an extension ring. (See figure 5.).
