The box shown at _ will have sufficient volume for this installation. Additionally, a 12 AWG grounding conductor is installed. The box will contain three 3-way switches.Nine 14 AWG "travelers" are pulled into the box along with four 12 AWG circuit conductors. One of these 3-gang masonry boxes will have several EMT conduits connected to it. Either I nor II A shallow box is shown at I and a deep box is shown at II in Figure 115.105. ![]() 600 For residential wiring, not less than one 15-ampere lighting branch circuit should be provided for every _ square feet of floor area. Hint: don't forget to count the wires for the device and the ground(s) that are in the MC cable. There are NO cable clamps within this box. If the cables entering this box were all #12 MC cables, could a 3" × 2" × 3½" deep metal device (switch) box be used here? The MC cables will be connected to the box using external connectors. You are required to size the box that will contain a split-wired receptacle. No Refer to partial circuit plan shown in Figure 115.103. The MC cables will be connected to the box using externalconnectors. If the cables entering this box were all #12 MC cables, what is the smallest 4" square (1900) metal box that could be used here? The box will have a 1"-rise plaster ring installed that adds a volume of 6.1 in3 to the total volume. 1 1/2 Refer to partial circuit plan shown in Figure 115.103. This means that when everything connected to all circuits is ON then the current in _ feeder conductors are equal, or as close as possible. the two "hot" Section 210.11(B) in the NEC® requires that loads be evenly proportioned (or balanced) among the different circuits in a panelboard. As you can see, the cable connectors are external (outside the box). The "pigtails" to both of the receptacles are #12 wires. You will install asecond receptacle in this box. The minimum volume required for this box is _ in3. 1 1/4" deep 4 11/16"-SQ box Which of the following boxes could be used for three each 10 AWG and six each 12 AWG conductors? 13 At 180 VA per outlet, how many outlets can be installed on a 20-ampere circuit (120 volt) if the circuit loading is to remain within its ratings? 30.0 Refer to Figure 115.104. ![]() 2 How many single receptacles can be installed in a two-gang box that is made using two single-gang boxes that are ganged together? Above certain electric baseboard heaters Where are electrical receptacle outlets not permitted to be located? Any of these: Arc-fault circuit interrupter Convenience receptacles that are installed in bedrooms in a house are required to be protected by a(n) _.
