UL 8750 was updated 4/28/2020 to fix a typo in Table 7.6 and to add an exception to Separation of Circuits of Wired Control Circuits described in Supplement SF. The exception allows Class 2, or equivalent, circuits. The Instructions shall also include a recommendation from the manufacturer to assure a cumulative leakage current of less than 3.5mA on the control circuit.
