Bond boxes are used for ground bed and drain point connection to the existing cable network. No. of terminals and dimension of boxes are different with respect to the no. and type of cables that are connected.

Test points are used to monitor pipe to earth potential at specific locations. Markers are used to pinpoint pipe/ ground bed location. Some of the markers are also used as test points.

PSN manufactures bond boxes from mild steel, stainless steel and anodized aluminum. Mild steel boxes are normally coated via a three layer electrostatic or alkyd paints to mitigate atmospheric corrosion.
