ABB 82181-1234-1 Box fire signal square steel 67cuin

5 SQUARE™ Fire signal box increased size and space added around the perimeter of an appliance helps to prevent ground faults and short circuits. also dramatically reduces stress on terminals, resulting in fewer damaged appliances. In addition, a major fire signal manufacturer allows a full complement of conductors to be routed in the box per NEC® Table 314.16(B) and also C.E.C. table 22, part 1. This allows additional circuits and zones to be pulled through the 5 SQUARETM Fire Signal Box, potentially reducing conduit. On a large construction project, these savings can really add up. Twice the volume as standard electrical boxes. Eliminate troubleshooting time and costs.
