For Consultants & Design Engineers
Earthing Materials for Electrical Consultants
You write the clause. We supply exactly what it says. A Material Test Certificate ships with every order. Most of our consultant work starts the same way — someone sends us an earthing specification and asks whether we can meet it. Usually we can, and we'll tell you straight away if we can't.
How We Work
What we actually do for you
Match material to the clause
Send us the earthing clause from your spec or tender and we’ll confirm which material it calls for — or tell you where the clause is ambiguous. GI strip to IS 2062, pipe to IS 1239, and for copper, the section and dimensions the clause specifies. We supply material; we don’t sign off designs.
A Material Test Certificate on every order
Not on request. Not for an extra fee. A Material Test Certificate ships with every order, at no extra cost, for your client’s handover file. How to read the certificate.
Stocked in Bengaluru, against your schedule
GI strip (GI patti) in eight sizes from 25×3 to 75×12 mm, copper earthing strip stocked in Bengaluru in 25×3, 25×6, 40×6 and 50×6 mm, GI earthing pipe to IS 1239 in 40, 50 and 80 mm, and earthing plates — held at our Rajajinagar shop. Ask against the exact requirement before you write a supply assumption into your schedule.
An honest answer on what we don't do
We are a materials supplier, not an installation contractor and not a design consultancy. We won't sign off your design. What we will do is make sure the metal that arrives on site is the metal your drawing asked for.
Free Tools
Tools you'll actually use
Free, no sign-up. Each one shows its formula and the source of its numbers, so you can check the working rather than take it on trust.
Conductor Size Calculator
Adiabatic sizing, S = I√t / k, with IEC 60364-5-54 k-factors for GI and copper. Gives the thermal minimum — corrosion and standard minimum sizes still apply on top.

Dwight / IEEE-80 rod formula. Parallel pits are shown as a range, not R ÷ n, because electrodes sit in each other's resistance field and never reach the ideal.

Turns soil resistivity and a target resistance into a materials list, sized against the realistic parallel figure rather than the optimistic one.
Open the calculator →Please read. These figures are general projections, not a design. They are estimates based on published formulae, standard weight data and assumed uniform soil conditions — real sites vary, and the numbers here may not be 100% accurate. They are offered as a working aid only. Global Electric Company accepts no liability for decisions taken on the basis of these results: always have them checked and signed off by your site engineer, electrical consultant or a qualified professional, and confirm earth resistance by measurement on site before commissioning. Where these tools and IS 3043 disagree, IS 3043 wins.
Worth Knowing
The standards, straight from the source
We don't republish IS 3043 or paraphrase it — BIS holds the copyright and is the only source guaranteed to be current. Our reference library is a curated set of links to the official BIS and CEA documents, with a plain-English note on what each one actually governs. If you need the authoritative text, it tells you exactly where to get it.
Send Us the Clause
Paste the earthing specification from your drawing or tender. We'll tell you what it needs and confirm we can supply it — usually within the hour.
