Charts (continued)To use the Table of Voltage Losses for Annealed Copper Wire on the previous page:To find the voltage loss for a two wire circuit, multiply the loss per 1000 feet figure above bytwice the actual wire length expressed in thousands.For a single wire, multiply the loss per 1000 feet value, above by the actual wire length inthousands.Note: Remember, amperages are additive along a wire where current is demanded by more thanone appliance.Note: Voltage losses are calculated from the formula: V = IRWhere: I = current in amperes, R = resistance in ohms per 1000 ft, V = voltageReference Chart Approximate Number of Wires to be Installed in Conduit or TubingMaximum no. of wires in conduit or sleevingWire Size(AWG) ½" ¾" 1" 1¼" 1½" 2" 2½" 3" 3½" 4" 5" 6"Wire Size(AWG)18 6 12 20 35 49 80 110 175 1816 5 10 16 30 42 67 97 150 1614 4 6 10 18 25 40 56 88 120 150 1412 3 5 7 15 20 33 50 75 102 130 205 1210 1 3 6 13 16 27 40 63 85 110 170 108 1 2 4 6 9 16 25 35 50 65 105 150 86 1 1 3 3 5 10 15 22 32 40 63 92 64 1 1 2 4 7 10 16 24 30 48 70 42 1 1 2 2 5 9 12 18 22 36 54 20 1 1 2 3 5 8 12 15 24 36 00 1 1 1 2 4 7 10 14 21 31 00 1 1 2 3 6 8 11 18 26 00 1 1 1 2 5 7 10 15 22 0Estimating Pipe SizeCopper Pipe Galvanized (Sch. 40 Steel) PVC PipeNominal Pipe SizeApproximate String Length in Inches½" 2" 2 5 ⁄8" 2 5 ⁄8"5⁄8" 2¾" – –¾" 2¾" 3 5 ⁄16" 3 5 ⁄16"1" 3½" 4 1 ⁄8" 4 1 ⁄8"1¼" 4 5 ⁄16" 5 3 ⁄16" 5 3 ⁄16"1½" 5 1 ⁄8" 6" 6"2" 6¾" 7 7 ⁄16" 7 7 ⁄16"To determine the nominal size of a pipe, wrap a string around the pipe and compare its length tothe chart above.18
