• How Are Busways (Bus Ducts) Connected Together?

  Busways are connected using specialized modular Joint Blocks (or Joint Paks). The connection process involves meticulously cleaning the conductor terminals to minimize contact resistance, aligning the sections, and securing the joint blo...

• How do you seal a busway penetration through a fire-rated wall?

  To properly seal a busway penetrating a fire-rated wall, you must install a factory-supplied fire barrier flange kit and pack the annular space (the gap between the busway housing and the wall opening) with a UL-classified intumescent fi...

• Why are copper busbars tinned or silver-plated?

  Copper busbars are tinned or silver-plated primarily to prevent surface oxidation, reduce contact resistance at joint connections, and extend the overall lifespan of the electrical distribution system. While bare, high-purity copper is a...

• Where should I use cast-resin busways (IP68) instead of sandwich busways?

  You should use IP68 cast-resin busways in environments exposed to extreme moisture, corrosive chemicals, or heavy dust, such as outdoor utility trenches, chemical plants, and shipyards. Unlike standard indoor sandwich busways, cast-resin...

• What are the performance limits of fire-rated busway vs. cast-resin busway?

  Fire-rated busway is engineered to maintain electrical integrity during active fires, prioritizing life safety, whereas cast-resin busway is built for total environmental immunity, focusing on waterproof and chemical-resistant durability...
