THR4-S S ERIES POWER SYSTEM 2.2.2.2 Individual feed A system with an individual feed AC architecture feeds each power module slot with an AC feed. There are two different styles of individual feeds for this system. The first style of connection is made via rear accessed compression style terminal blocks see Figure 6. - Page 8 THR4-S S ERIES POWER SYSTEM For this example we will assume that future growth is necessary so we will size the AC feed for four power modules. Using Table 4, each AC feed, to the pair of TH120048, power modules will require will require a 20 amp breaker with 12 AWG wire, at high line, per feed.
