ETS standard switchroom earth bars are manufactured from high conductivity 50x6mm copper to BS1433/BS2874-C11, with a typical copper purity content in excess of 99.9%.
M10 x 35mm brass machine screws are used throughout the range for earth conductor or lug termination. 50mm centres are provided between each screw fixing to allow for connection of cable lugs up to 400mm2 or 50mm wide earthing tapes. Each fixing is supplied with two brass hexagon nuts and brass washer.
Each hard-drawn copper earth bar is supplied fully assembled on a galvanised steel channel base, zinc coated to BS2989:1982, grade Z2. The base profile allows for immediate installation, without the need to disassemble the earth bar, 6mm diameter holes being provided for screw-fixing to walls or containment structures.
The nylon insulators are rated up to 1000v AC and feature M10 brass threaded inserts.
Available from stock with either: 4, 6, 8, 10, 12 or 20 x M10 brass stud assemblies.
We also offer a bespoke earthbar manufacturing service where any combination of bar size, incoming or outgoing studs and disconnectable links can be quickly produced to your precise requirements. Please contact our Sales Team with your earthing requirements.
