Electrical Wiring Residential 18Th Edition Chapter 5 Answers - A.) How high above the finished floor inside the residing room are receptacles located? 12in, (pg. Forty nine) out of doors receptacle shops in this residing are placed 18 in. Above grade. (Pg. Forty nine) within the spaces furnished, draw the correct symbol for every of the descriptions indexed in (a) via (r).??no longer protected within the analyzing assignment the front edge of a box hooked up in a combustible wall need to be flush with the completed surface. (Pg. 35) list the maximum number of 12 awg conductors approved in a: (pg. Forty four—desk 314.Sixteen(a) a.) 4 in. X 1½ in. Octagon box. ----------------6 b.) Four-eleven/16 in. X 1½ in. Square field.-----------Thirteen c.) Three in. X 2 in. X three½ in. Tool box. ----------Eight. Two 12/2 and 14/2 nonmetallic-sheathed awg cables enter a box. Every cable has an system grounding conductor. The 12 awg conductors are linked to a receptacle. Of the 14 awg conductors are linked to a toggle transfer. The alternative two 14 awg conductors are spliced together considering the fact that they function a switch loop. The box includes cable clamps. Calculate the minimum cubic-inch extent required for the box. Solution: floor twine----#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. Gadgets: 1—toggle switch –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. Using the identical quantity and length of conductors as in questions 28, but the usage of electric metallic tubing, calculate the minimal cubic-inch extent required for the box. There can be no separate device grounding conductors, nor will there be any clamps in the box. Answer: floor wire—should figure on one ground wire because of the nearby code requirement of all conduit structures requiring a ground cord. The answers could be the same due to the fact the electrical steel tubing would require using metallic connectors that need to input the field, you would count number them as fittings, which means that that regardless of how many fittings are coming into the container the you will parent it at ( 1-instances the cubic inch of the most important conductor that enters the field. To allow for ok conductor duration at electrical outlet and tool boxed to make up connections, three hundred.14 calls for that not much less than [ 3 in.(75 mm). 6 in. (150 mm), 9 in. (225 mm)] of conductor duration be supplied. This period is measured from in which the conductor emerges from the cable or raceway to the cease of the conductor. For container openings having any size much less than 8in. (200mm), the minimum period of conductor measured shape the container beginning in the wall to the end of the conductor is [ 3 in. (75 mm), 6 in. (One hundred fifty mm), nine in. (225 mm). Circle the ideal answer. Answer web page 21 determine 2-2 while wiring a residence, what must be considered whilst installing wall boxes on each facets of a not unusual partition that separates the storage and a liveable room? The hearth score of the partitions have to be maintained which means that that bins may not be set up “lower back to again” or inside the equal air void. A separation of 24 inches horizontal ought to be maintained until the packing containers are indexed as being hearth resistant. The boxes that are on the fireplace rated wall should be properly covered or encased with a fire puddy. Does the nec® allow steel raceways to be used with nonmetallic bins? Sure _____x______ no__________ nec®______nec® 314.Three (exception) –previded that each one steel raceways or cables getting into the box are bonded collectively to maintanin the integrity of the grounding direction to other gadget inside the set up.
