Overview

Sandwich construction busbar trunking replaces large parallel cable runs with a compact, low-impedance link that is easier to route, quicker to install and far simpler to tap into later. Epoxy-insulated conductors are clamped face to face, which keeps the voltage drop and the magnetic field low, and plug-in tap-off boxes let floors be fed without cutting the run.
