7 Appendix 2 The Relationship between the 24V AC Cable Diameter and the Transmission Distance It is the recommended transmission distance when the cable diameter is fixed and the 24V AC power consumption is below 10%. For the AC device, the max permission voltage power consumption is 10%. For example, when a device of rated power 80VA installed from the transformer 35 inches (10m), then the min cable diameter is 0.8000mm. mm Feet（m） 0.8000 1.000 1.250 2.000 W 10 283 (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) 100 28 (8) 45 (13) 71 (21) 181 (55) 110 25 (7) 41 (12) 65 (19) 164 (49) 120 23 (7) 37 (11) 59 (17) 150 (45) 130 21 (6) 34 (10) 55 (16) 139 (42) 140 20 (6) 32 (9) 51 (15) 129 (39) 150 18 (5) 30 (9) 47 (14) 120 (36) 160 17 (5) 28 (8) 44 (13) 113 (34) 170 16 (4) 26 (7) 42 (12) 106 (32) 180 15 (4) 25 (7) 39 (11) 100 (30) 190 14 (4) 23 (7) 37 (11) 95 (28) 200 14 (4) 22 （6) 35 (10) 90 (27) 27

Appendix 2 The Relationship between the 24V AC Cable

Diameter and the Transmission Distance

It is the recommended transmission distance when the cable diameter is fixed and the 24V AC power

consumption is below 10%. For the AC device, the max permission voltage power consumption is 10%.

For example, when a device of rated power 80VA installed from the transformer 35 inches (10m), then

the min cable diameter is 0.8000mm.
