Description
The Type GF earth clamp connects one earth conductor to flat metal. It has a cast copper alloy body and stainless steel hardware. Two versions cover conductor sizes from 16 to 135 mm², with a separate diameter range listed for each size.
Type GF earth clamp sizes
- ER-GF42: one conductor, 16–70 mm², with a conductor diameter of 5.10–10.70 mm.
- ER-GF58: one conductor, 70–135 mm², with a conductor diameter of 10.70–15.25 mm.
Since the ranges differ, choose the part number using both the conductor area and its diameter. The mm² value describes the conductor cross-section, while the mm value gives its diameter. Checking both helps you select the clamp for the cable used on the job.
Construction and purpose
- Application: clamping earth cable to flat metal.
- Body: cast copper alloy.
- Hardware: stainless steel.
- Conductors per clamp: one.
- Product group SKU: ER-GF.
The curved body holds the conductor at the connection point. The bolt and nut form the fastening arrangement shown in the product photograph.
Check the connection before ordering
First, confirm that the job needs a conductor-to-flat-metal connection. Then check the conductor range for ER-GF42 or ER-GF58. Also confirm the bar thickness and mounting arrangement with our team if you need help matching an existing installation.
For a conductor-to-rod connection, however, compare the separate EP1 earth rod clamp and its rod and cable ranges. This gives you a way to compare the connection types before choosing a part.
Also, the Type GF size table is on printed page 152 of the Engineering Supplies catalogue.
Order and product support
Finally, select ER-GF42 or ER-GF58 from the ordering table and enter your quantity. For help with conductor size or flat-bar fit, call Engineering Supplies on (08) 9258 8444 or email sales@engsup.com.au. Include the part number and connection details with your enquiry.
