FAQs
The GRC1 is designed for direct burial service-entrance grounding. To install, position the clamp on the grounding conductor within the 1/2 inch range, ensure solid contact with the conductor surface, and secure firmly to the grounding electrode or conduit system as per NEC/CEC guidelines. The copper-alloy construction promotes durable contact, while the regular burial design reduces exposure risks in outdoor systems.
The GRC1 supports NEC/CEC standards and is suitable for ordinary or non-hazardous locations. Canadian certification resources are available through UL-listed Canadian pages, confirming compliance for field installations in Canada. This combination helps ensure regulatory alignment across North American projects.
Yes. The GRC1 is specified for ordinary/non-hazardous locations and includes direct burial capability, making it well-suited for outdoor service entrances in manufacturing facilities, data centers, and non-hazardous outdoor electrical installations. Copper alloy construction adds corrosion resistance for long-term performance.
Canadian certification information is available via UL Canada pages referenced in Eaton’s documentation. These certifications affirm compliance for service entrance grounding clamps used in Canadian facilities, reducing regulatory risk during inspections and commissioning.
Using the GRC1 can shorten installation time due to its direct burial suitability and 1/2 inch clamping range, while improving reliability through copper-alloy corrosion resistance. This reduces maintenance costs, mitigates grounding faults, and supports faster commissioning in NEC/CEC-compliant projects.
