Electrical Wiring Residential Mullin Pdf - 12/2 and two 14/2 nonmetallic-sheathed awg cables input a box. Every cable has an system grounding conductor. The 12 awg conductors are linked to a receptacle. Two of the 14 awg conductors are related to a toggle switch. The other 14 awg conductors are spliced together on account that they function a switch loop. The field includes two cable clamps. Calculate the minimum cubic-inch volume required for the container. Solution: ground cord----#12 (2.25cu. In.)??1 x 2.25 ----------2.25 cu. In. Conductors: 2—#12/2 ---- 2 x 2 x 2.25 ------------------------------9.00 cu. In. 2—#14/2 ---- 2 x 2 x 2.00 ------------------------------8.00 cu. In. Devices: 1—toggle transfer –1 x 2 x 2.25 ------------------------4.50 cu. In. 1—receptacle –1 x 2 x 2.25 ----------------------------4.50 cu. In. Fittings (clamps) 2—cable clamps—1 x 2.25 ----------------------------2.25 cu. In. ------------------------------------------------------------- 31.50 cu. In. The usage of the same wide variety and size of conductors as in questions 28, but using electrical metal tubing, calculate the minimum cubic-inch quantity required for the container. There will be no separate equipment grounding conductors, nor will there be any clamps in the container. Solution: floor wire—ought to discern on one floor cord due to the nearby code requirement of all conduit systems requiring a floor cord. The solutions may be the same because the electrical steel tubing would require the usage of metal connectors that need to input the box, you'll count number them as fittings, which means that that no matter how many fittings are getting into the container the you may determine it at ( 1-times the cubic inch of the largest conductor that enters the container. To allow for adequate conductor length at electrical outlet and tool boxed to make up connections, three hundred.14 requires that no longer much less than [ 3 in.(75 mm). 6 in. (150 mm), 9 in. (225 mm)] of conductor period be provided. This duration is measured from in which the conductor emerges from the cable or raceway to the give up of the conductor. For box openings having any size much less than 8in. (200mm), the minimal period of conductor measured shape the field beginning within the wall to the end of the conductor is [ three in. (Seventy five mm), 6 in. (150 mm), nine in. (225 mm). Circle the correct answer. Answer page 21 figure 2-2 while wiring a house, what need to be taken into consideration while putting in wall containers on both aspects of a not unusual partition that separates the storage and a liveable room? The hearth score of the partitions need to be maintained this means that that bins won't be mounted “returned to returned” or inside the same air void. A separation of 24 inches horizontal ought to be maintained until the boxes are indexed as being hearth resistant. The bins that are at the fire rated wall should be nicely protected or encased with a fireplace puddy. Does the nec® allow steel raceways for use with nonmetallic containers? Yes _____x______ no__________ nec®______nec® 314.Three (exception) –previded that all metallic raceways or cables entering the box are bonded collectively to maintanin the integrity of the grounding route to different equipment within the installation.
