I had twin Buss brand breakers but I really want a double pole breaker. Opened up the Watts247 and it looks way overkill for a 55v system with the huge “arc chute”. Rigged up a box to put it in, tined buss bar and precharge button(DPDT) and indicator lamp. The buss can hold up the eight lugs, four on bottom close to the wall and four on top. Only using two for now sandwiched between the breaker terminals and buss. Couldn’t use the 20ma led lamp in the button because it actually was partially defeating the discharge resistor of the inverter?! Found one that was much less amperage. Diodes keep any cross transfer in the lamp circuit when the breaker is open.
