Brilliant Electrical Wiring Residential 18Th Edition Chapter 5 Review Answers Photos - A.) How high above the completed ground in the residing room are receptacles placed? 12in, (pg. 49) out of doors receptacle retailers on this dwelling are located 18 in. Above grade. (Pg. Forty nine) in the areas provided, draw the precise image for each of the descriptions indexed in (a) thru (r).??no longer covered within the studying assignment the the front edge of a container established in a flamable wall must be flush with the finished floor. (Pg. 35) listing the maximum wide variety of 12 awg conductors accredited in a: (pg. 44—desk 314.Sixteen(a) a.) 4 in. X 1½ in. Octagon field. ----------------6 b.) Four-eleven/16 in. X 1½ in. Rectangular field.-----------13 c.) 3 in. X 2 in. X three½ in. Device field. ----------Eight.

12/2 and two 14/2 nonmetallic-sheathed awg cables input a container. Every cable has an equipment grounding conductor. The 12 awg conductors are linked to a receptacle. Two of the 14 awg conductors are linked to a toggle transfer. The opposite two 14 awg conductors are spliced collectively due to the fact they serve as a transfer loop. The box includes cable clamps. Calculate the minimum cubic-inch volume required for the box. Solution: floor 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 ------------------------------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 identical quantity and length of conductors as in questions 28, but the use of electrical metal tubing, calculate the minimum cubic-inch quantity required for the container. There will be no separate device grounding conductors, nor will there be any clamps within the field. Answer: ground wire—must discern on one floor wire due to the local code requirement of all conduit structures requiring a floor twine. The solutions might be the equal because the electrical steel tubing would require the use of metallic connectors that should input the container, you'll remember them as fittings, which means that that no matter how many fittings are coming into the box the you will discern it at ( 1-times the cubic inch of the most important conductor that enters the box. To permit for good enough conductor duration at electrical outlet and tool boxed to make up connections, three hundred.14 requires that now not much less than [ 3 in.(75 mm). 6 in. (150 mm), 9 in. (225 mm)] of conductor length be furnished. This duration is measured from in which the conductor emerges from the cable or raceway to the cease of the conductor. For container openings having any dimension much less than 8in. (200mm), the minimum duration of conductor measured form the container commencing inside the wall to the cease of the conductor is [ three in. (Seventy five mm), 6 in. (A hundred and fifty mm), 9 in. (225 mm). Circle the precise solution. Answer web page 21 discern 2-2 whilst wiring a residence, what must be considered while putting in wall packing containers on both facets of a commonplace partition that separates the garage and a liveable room? The fire score of the partitions should be maintained which means that bins may not be hooked up “returned to back” or inside the equal air void. A separation of 24 inches horizontal have to be maintained except the boxes are listed as being hearth resistant. The bins which are on the fire rated wall need to be well blanketed or encased with a hearth puddy. Does the nec® allow steel raceways to be used with nonmetallic bins? Yes _____x______ no__________ nec®______nec® 314.3 (exception) –previded that each one steel raceways or cables coming into the field are bonded together to maintanin the integrity of the grounding route to other device in the installation.
