Earthing Chambers
Cast iron and RCC inspection chambers housing the earth electrode, backfill compound, and test link — built to IS 3043 so fault current has a low-resistance, maintenance-accessible path to ground.

Construction
Each chamber is built to house a vertical GI electrode set in backfill compound to lower soil resistivity, with a removable inspection cover for periodic earth resistance testing. Chamber depth is matched to your site's soil resistivity and fault current requirement.
Available in cast iron covers for vehicular/pedestrian areas and RCC construction for permanent installations.
Need the earth rod/electrode itself? We also help source GI earth rods — ask us along with your chamber quote.
Four chamber families covering light-duty landscaping through heavy vehicular-load sites. Tell us your cover load requirement and we'll confirm the right size.
Square PP Chamber Covers
Lightweight polypropylene body — easy to handle on site, resists corrosion, suited to light and medium pedestrian-duty areas.
| Model | Size (W × D × H) | Load Rating |
|---|---|---|
| UP-SQ-200 | 245 × 245 × 195 mm | Light Duty (3T) |
| UP-SQ-300M | 310 × 310 × 225 mm | Medium Duty (5T) |
| UP-SQ-300H | 310 × 310 × 225 mm | Heavy Duty (7T) |
| UP-SQ-500 | 500 × 500 × 315 mm | Extra Heavy Duty (10T) |
RCC / Concrete Chamber Covers
Reinforced concrete construction for permanent installations where long-term structural load bearing matters more than handling weight.
| Model | Size (W × D × H) | Load Rating |
|---|---|---|
| UP-RC-300 | 300 × 300 × 170 mm | Medium Duty (5T) |
| UP-RC-320 | 320 × 320 × 190 mm | Medium Duty (5T) |
| UP-RC-450 | 450 × 450 × 400 mm | Heavy Duty (10–20T) |
MS / CI Metal Chamber Covers
Mild steel or cast iron covers for vehicular-traffic areas and industrial yards needing the highest load tolerance.
| Model | Size | Load Rating |
|---|---|---|
| UP-MC-300 | 300 mm | Medium–Heavy Duty (5–10T) |
| UP-MC-450 | 450 mm | Heavy Duty (10T) |
Round PP Chamber Covers
Circular polypropylene chambers, a compact footprint for tighter installation areas and standard residential/commercial earthing.
| Model | Top / Bottom Dia. × Height | Load Rating |
|---|---|---|
| UP-RD-175 | 175 / 250 mm × 240 mm | Light Duty (3T) |
| UP-RD-245 | 245 / 330 mm × 265 mm | Light Duty (3T) |
Dimensions and load ratings shown are standard offerings — custom sizes available on request.
Fault Current to Earth
When a fault occurs, current travels down the electrode through the backfill compound and disperses into the surrounding soil — the chamber gives you access to the test link at ground level to verify this path stays low-resistance over time.
Chamber depth (up to 3000mm) and electrode type are selected based on your site's measured soil resistivity, per IS 3043.

What size earthing chamber do I need?
It depends on the cover load rating your site needs — light-duty (3T) for pedestrian/landscaped areas, medium (5T) for general commercial sites, and heavy or extra-heavy duty (7-20T) for vehicular traffic and industrial yards. Chamber depth is matched separately to your site's soil resistivity, up to 3000mm.
Do you supply earthing chambers across South India?
Yes. We are based in Hyderabad, Telangana, and regularly dispatch earthing chambers to Andhra Pradesh, Karnataka, Tamil Nadu and Kerala, with PAN-India delivery available for larger orders.
Can chamber size and cover type be customized?
Yes — the dimensions and load ratings on this page are our standard offerings. Custom sizes, cover materials, and electrode configurations are available on request based on your site spec.
Need a Chamber Sized for Your Site?
Send us soil resistivity and fault current data if available — we'll recommend the right chamber and electrode.
