Brass earth tags—also known as brass earthing tags, brass grounding tags, or brass earth labels—are essential electrical components used to identify, mark, and maintain grounding connections in electrical systems. Manufactured from high-grade brass alloys in Jamnagar, India, these tags offer unparalleled corrosion resistance, electrical conductivity, and long service life. Jamnagar Brass Components supplies brass earth tags to clients across the United States, Canada, the UK, Europe, and the Middle East, meeting all major international standards.
What Are Brass Earth Tags?
Brass earth tags are small, flat metal plates or rings with a stamped or engraved earth symbol (the standard grounding symbol ⏚) along with an optional alphanumeric identifier. They are crimped, bolted, or soldered onto grounding cables, busbar assemblies, electrical panels, distribution boards, switchgear, and cable tray systems to clearly identify grounding (earthing) conductors and provide secure, low-resistance electrical connections.
These tags serve a dual purpose: they act as identifiers for maintenance personnel and also provide a reliable mechanical and electrical termination point. Their use is mandated by NEC (National Electrical Code), IEC 60364, BS 7671, and other major electrical codes.

Frequently Asked Questions (FAQs) – Brass Earth Tags
Q1. What is a brass earth tag used for?
A brass earth tag is used to identify, mark, and provide a secure electrical grounding (earthing) connection point on cables, busbars, equipment enclosures, and electrical panels. It helps maintenance personnel quickly identify protective earth conductors and ensures that grounding connections remain firm and identifiable throughout the life of the installation.
Q2. Are brass earth tags compliant with the NEC (National Electrical Code)?
Yes. Brass earth tags manufactured from C36000 or equivalent brass alloys are compatible with NEC requirements for grounding conductor identification under Article 250. The green/yellow PVC-sleeved versions are specifically designed to meet NEC color-coding requirements for equipment grounding conductors (EGC).
Q3. What brass grade is best for earth tags?
The most widely used grades are CW614N (EN / European standard) and C36000 (ASTM / USA standard), both free-cutting brass alloys offering excellent machinability, good conductivity (~26% IACS), and inherent corrosion resistance. For lead-free/RoHS applications, C69300 (ECO Brass®) is recommended.
Q4. Can brass earth tags be used outdoors?
Yes, provided they are fitted with appropriate corrosion protection. Nickel-plated or hot-dip-tinned brass earth tags are suitable for outdoor, humid, and coastal environments. For underground use, we recommend additional encapsulation or use of stainless steel alternatives.
Q5. What sizes of brass earth tags do you supply?
We supply brass earth tags from 6 mm to 16 mm width as standard, with hole diameters from 3.2 mm to 8.2 mm, suitable for cable sizes from 0.5 mm² to 70 mm². Custom sizes up to 400 mm² cable capacity are available on request.
Q6. Do you provide custom engraving or stamping on brass earth tags?
Yes. We offer custom numbering, alphanumeric codes, company logos, and earth symbols stamped or laser-engraved on brass earth tags. Minimum order quantities apply for bespoke engraving/stamping.
Q7. What is the difference between an earth tag and a cable lug?
A cable lug (also called a cable terminal) is primarily a conductor termination device that mechanically and electrically joins a cable conductor to a terminal stud. An earth tag is specifically a grounding/identification device, often thinner and more compact, used to mark and maintain the integrity of protective earth connections. Some earth tags incorporate both functions.
Q8. Are your brass earth tags RoHS compliant?
Yes. We offer RoHS-compliant (lead-free) brass earth tags manufactured from C69300 (ECO Brass®) or CW511L alloys. Standard CW614N/C36000 grades contain lead (as a machining aid) and are not RoHS compliant. Please specify your compliance requirement when ordering.
Q9. What surface finishes are available for brass earth tags?
Available finishes include: Natural Brass (mill finish), Bright Tin Plating, Electro-Tinning, Nickel Plating, and Hot-Dip Tinning. Custom finishes are available on request.
Q10. What is the minimum order quantity (MOQ) for brass earth tags?
For standard sizes and natural brass finish, our MOQ is 500 pieces. For custom sizes, engravings, or specialty plating, the MOQ is 1,000 pieces. Sample quantities (25–50 pcs) are available for approval prior to bulk orders.
Q11. Do you export brass earth tags to the USA?
Absolutely. The USA is one of our primary export markets. We ship to major US ports (Los Angeles, New York, Houston, Chicago) via sea freight (FCL/LCL) or air freight for urgent orders. We provide all required export documentation including Certificate of Origin, Packing List, Commercial Invoice, and Material Test Certificates.
Q12. How long does delivery take for brass earth tags?
Standard stock items are dispatched within 5–7 working days. Custom orders with special dimensions, plating, or engraving typically require 3–4 weeks production lead time. Air freight to US destinations takes 3–5 days; sea freight LCL typically 18–25 days to US East Coast / West Coast ports.
Q13. Can you supply brass earth tags to electrical wholesalers and distributors?
Yes. We actively supply electrical wholesalers, MRO distributors, OEM manufacturers, and electrical contractors across the USA, Canada, UK, Europe, and Australia. Trade pricing and private-label packaging are available for qualifying distributors.
Q14. What quality certifications do you hold?
Jamnagar Brass Components holds ISO 9001:2015 certification. All products can be supplied with material test certificates (MTC), dimensional inspection reports, RoHS/REACH compliance declarations, and third-party inspection by SGS, Bureau Veritas, or TÜV on request.
