Electrical Wiring Residential 17Th Edition Chapter 4 Answers - A.) How excessive above the finished floor within the living room are receptacles positioned? 12in, (pg. Forty nine) outdoor receptacle stores in this dwelling are positioned 18 in. Above grade. (Pg. 49) inside the areas provided, draw the perfect image for every of the descriptions indexed in (a) thru (r).??no longer covered in the studying undertaking the front edge of a field set up in a combustible wall must be flush with the completed surface. (Pg. 35) list the maximum variety of 12 awg conductors permitted in a: (pg. Forty four—table 314.Sixteen(a) a.) 4 in. X 1½ in. Octagon box. ----------------6 b.) 4-eleven/16 in. X 1½ in. Rectangular box.-----------13 c.) Three in. X 2 in. X 3½ in. Tool container. ----------Eight.

12/2 and 14/2 nonmetallic-sheathed awg cables input a box. Every cable has an equipment grounding conductor. The 12 awg conductors are connected to a receptacle. Two of the 14 awg conductors are related to a toggle transfer. The opposite 14 awg conductors are spliced together due to the fact they function a transfer loop. The container consists of two cable clamps. Calculate the minimum cubic-inch quantity required for the field. Solution: floor wire----#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. Gadgets: 1—toggle transfer –1 x 2 x 2.25 ------------------------four.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 equal wide variety and length of conductors as in questions 28, but the usage of electrical metallic tubing, calculate the minimal cubic-inch extent required for the field. There may be no separate equipment grounding conductors, nor will there be any clamps inside the container. Solution: ground wire—must figure on one floor twine due to the nearby code requirement of all conduit structures requiring a floor twine. The solutions might be the identical due to the fact the electric steel tubing would require using steel connectors that must input the field, you will depend them as fittings, which means that that irrespective of how many fittings are entering the field the you'll figure it at ( 1-times the cubic inch of the biggest conductor that enters the field. To permit for good enough conductor length at electric outlet and tool boxed to make up connections, 300.14 calls for that no longer much less than [ 3 in.(75 mm). 6 in. (150 mm), 9 in. (225 mm)] of conductor duration be supplied. This length is measured from in which the conductor emerges from the cable or raceway to the stop of the conductor. For field openings having any measurement less than 8in. (200mm), the minimum duration of conductor measured form the box commencing in the wall to the give up of the conductor is [ 3 in. (Seventy five mm), 6 in. (150 mm), 9 in. (225 mm). Circle the proper solution. Answer page 21 discern 2-2 when wiring a house, what must be considered whilst installing wall containers on each facets of a commonplace partition that separates the storage and a liveable room? The fire score of the partitions should be maintained which means that that packing containers may not be installed “returned to lower back” or inside the identical air void. A separation of 24 inches horizontal have to be maintained unless the packing containers are listed as being fire resistant. The packing containers which are at the fire rated wall need to be well blanketed or encased with a fire puddy. Does the nec® permit metallic raceways to be used with nonmetallic packing containers? Sure _____x______ no__________ nec®______nec® 314.3 (exception) –previded that all metallic raceways or cables coming into the field are bonded collectively to maintanin the integrity of the grounding route to other equipment in the installation.
