Description

EP4 earth rod clamp for two conductors

The EP4 earth rod clamp connects two earth conductors in parallel with the rod. It suits a conductor cross-section range of 50–120 mm², with a listed conductor diameter range of 8.90–14.21 mm. Engineering Supplies identifies this clamp as ER-EP4.

The body is an alloy casting with a high copper content. Stainless steel hardware completes the assembly. Its two-conductor arrangement is useful when the earthing design calls for both conductors to run along the rod at the connection.

EP4 materials and conductor sizes

• Part number: ER-EP4

Check rod fit before ordering

Please confirm the rod diameter with Engineering Supplies before ordering this clamp. Provide the rod part number and outside diameter so we can check the supplied EP4 version against your installation.

Also check both conductors against the listed size range. Use the actual conductor diameter as well as its cross-sectional area when assessing the connection. Then confirm that a parallel layout matches the project drawing and the available space.

For a single conductor running parallel to the rod, compare the EP1 earth rod clamp. The conductor count and size limits differ, so select the clamp by the required connection arrangement.

Reference information and support

The EP4 connection layout appears in the PLP earth rod brochure. Use the relevant fitting instructions when assembling and tightening a connection, and match the component materials to the earthing design.
