Answers To Electrical Wiring Residential 18Th Edition - Two 12/2 and 14/2 nonmetallic-sheathed awg cables input a field. Each cable has an gadget grounding conductor. The 12 awg conductors are linked to a receptacle. Of the 14 awg conductors are connected to a toggle transfer. The alternative 14 awg conductors are spliced together considering they function a transfer loop. The field consists of cable clamps. Calculate the minimum cubic-inch extent required for the box. 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 ------------------------------nine.00 cu. In. 2—#14/2 ---- 2 x 2 x 2.00 ------------------------------eight.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 ----------------------------four.50 cu. In. Fittings (clamps) 2—cable clamps—1 x 2.25 ----------------------------2.25 cu. In. ------------------------------------------------------------- 31.50 cu. In. Using the identical range and size of conductors as in questions 28, however the usage of electric steel tubing, calculate the minimum cubic-inch quantity required for the field. There could be no separate gadget grounding conductors, nor will there be any clamps in the box. Answer: ground twine—ought to discern on one floor twine because of the local code requirement of all conduit systems requiring a ground cord. The solutions could be the same due to the fact the electric metallic tubing would require using steel connectors that have to enter the box, you would be counted them as fittings, which means that that irrespective of what number of fittings are getting into the box the you'll parent it at ( 1-times the cubic inch of the biggest conductor that enters the box. To allow for good enough conductor length at electrical outlet and device boxed to make up connections, three hundred.14 requires that now not less than [ 3 in.(75 mm). 6 in. (150 mm), 9 in. (225 mm)] of conductor duration be furnished. This duration is measured from in which the conductor emerges from the cable or raceway to the end of the conductor. For field openings having any measurement much less than 8in. (200mm), the minimum period of conductor measured form the container opening within the wall to the quit of the conductor is [ three in. (Seventy five mm), 6 in. (One hundred fifty mm), nine in. (225 mm). Circle the appropriate answer. Solution web page 21 parent 2-2 when wiring a residence, what have to be considered whilst putting in wall containers on both facets of a commonplace partition that separates the storage and a liveable room? The fireplace rating of the walls should be maintained because of this that bins might not be mounted “back to again” or within the identical air void. A separation of 24 inches horizontal need to be maintained until the bins are listed as being hearth resistant. The packing containers which can be at the fire rated wall ought to be well included or encased with a hearth puddy. Does the nec® permit steel raceways for use with nonmetallic bins? Sure _____x______ no__________ nec®______nec® 314.Three (exception) –previded that all steel raceways or cables getting into the container are bonded together to maintanin the integrity of the grounding direction to other device within the installation.
