I-Line Combo Panelboard
  • Features

    The I-Line™ Combo Panelboard saves time and space by combining I-Line and NQ/NF sections in one panelboard. The I-Line Combo Panelboard features a smart, space-saving design for fast installation and a smaller footprint, all with the proven reliability trusted for decades. And since you install one panelboard instead of two, you save on installation time, labor expenses, and material costs.
