A = For standard resistive loads, such as incandescent and halogen sources the maximum load is 350 watts. For optimum system performance, the value is adjusted for 2 x gang switch arrangements (280 watts) and 3 x gang switch arrangements (210 watts).
B = For standard LED loads with power factor performance of > 0.9, the maximum load is 200 watts. For optimum system performance, the value is adjusted for 2 x gang switch arrangements (150 watts) and 3 x gang switch arrangements (100 watts).
C = Motor Loads/ Iron Core Ballasts – no more than 80V AC max. (irrespective of the connected load in the case of iron core ballasts for garden lighting and other applications using iron core ballasts)
