1. 16 CABLE DIAMETER CALCULATION AND LIGHTNING amp SURGE PROTECTION Relation between 24VAC Cable Diameter and Transmission Distance In general the maximum allowable voltage loss rate is 10 for AC powered devices The table below shows the relationship between transmission power and maximum transmission distance under a certain specified cable diameter on condition that the 24VAC voltage loss rate is below 10 According to the table if a device rated at 50W is installed 17 meter away from the transformer the minimum cable diameter shall be 0 8000mm A lower diameter value tends to cause voltage loss and even system instability 17 Diameter mm 1 250 2 000 283 86 451 137 716 218 1811 551 20 141 42 225 68 358 109 905 275 30 94 28 150 45 238 72 603 183 40 70 21 112 34 179 54 452 137 50 56 17 90 27 143 43 362 110 60 47 14 75 22 119 36 301 91 70 40 12 64 19 102 31 258 78 80 35 10 56 17 89 27 226 68 90 31 9 50 15 79 24 201 61 00 28 8 45 13 71 21 81 55 10 25 7 41 12 65 19 64 49 20 23 7 37 11 59 17 50 45 30 21 6 34 10 55 16 39 42 20 6 32 9 51 15 29 39 20 36 44 13 13 34 70 6 4 26 7 42 12 06 32 180 5 4 25 7 39 11 00 30 90 4 4 23 7 37 11 95 28 35 10 90 27 Lightning amp Surge Prote2.
