Barrier Strips

Barrier strips are screw-type electrical connectors that allow more than one circuit to connect to another circuit. Wires are clamped down to a metal part by tightening of a screw. Multiple screw terminals are arranged such that the metal strips are separated by a barrier or insulating block.

How do barrier strips work?

Each strip will have a pair of screws arranged such that each screw connects to a separate conductor on either end of the strip. Alternatively, terminal strips have several screws along two strips, creating a bus bar for the distribution of power.

Barrier strips can accommodate a broad range of wire sizes and provide a reliable connection. The term “contact” refers to the wire attached to the barrier and the contact pitch refers to the distance between each contact, measured from the centre of each opening or hole.

Applications of Barrier strips

Barrier strips are extensively used in electrical wiring for distributing electricity, connecting switches, electrical outlets and lighting fixtures to the mains. They’re also used to directly connect major appliances such as ovens. You will also find barrier strips in surge protectors and speakers.
