Instruction Manual for the Eaton RTC-100 Automatic Transfer Switch Controller Active Load Control. 4.1.4 RTC-100 on board Active Load Control 4.1.4.1 Connections There are 2 relays on the RTC-100 that can be used to actively control up to 2 loads while connected to the generator source. The connections are on J8 located on the top of the board. Pins 1 and 2 are the primary load and pins 3 and 4 are the secondary load (see Figure 5). The primary load has priority over the secondary load.
