ELECTRICAL · Latur, Maharashtra
Electrical Contracting
The half of the job most solar companies ignore: the wiring, the board and the earthing that everything else depends on.
01 / Scope
What we actually do on site.
1.1
Load calculation
Circuit-by-circuit load schedule with diversity, so cable sizes and breaker ratings match reality and future additions.
1.2
Distribution boards
Neatly dressed boards with correctly rated MCBs, RCCB protection, labelled circuits and torqued terminations.
1.3
Wiring
Concealed or conduit wiring in ISI-marked cable, with proper looping, junctioning and separation of power and signal runs.
1.4
Earthing
Earthing pits installed and resistance-tested, with equipotential bonding for solar, pumps and heavy appliances.
1.5
Fault finding
Systematic tracing of tripping, leakage and voltage-drop complaints — measured, not swapped by guesswork.
1.6
Testing and handover
Insulation resistance, polarity, earth continuity and RCD trip tests recorded on a handover sheet.
02 / Single-line
How the electrical circuit is drawn before it is built.
Amber = live incomer path · each MCB way individually rated to its circuit
- DISCOM meter — Utility supply point
- Main MCB / isolator — Incomer protection
- Distribution board — RCCB + MCB ways
- Lighting circuit
- Power circuit
- Heavy appliance circuit
- Earthing pit — IS 3043, resistance-tested
03 / Process
Load calculation to certified handover.
01
Load calculation
Circuit-by-circuit load schedule with diversity, so cable and breaker sizes match the real building.
0.5–1 day·Written load schedule
02
Single-line diagram
The board drawn before it is built — every way, rating and label agreed on paper first.

Board build
Neatly dressed board with correctly rated MCB/RCCB, torqued terminations and labelled circuits.
1–3 days·Labelled, torqued distribution board
05
Earthing test
Pits installed and resistance-measured, with equipotential bonding for solar, pumps and heavy loads.
0.5–1 day·Earth resistance reading on record
06
Certification
Insulation resistance, polarity, earth continuity and RCD trip tests recorded on a handover sheet.
Half day·Signed test and handover sheet
04 / Specification
What goes into the bill of materials, and why.
| Item | Standard we specify | Why it matters |
|---|---|---|
| Wiring cable | ISI-marked FR/FRLS copper cable, sized to the load schedule not the conduit size | Undersized cable is the leading cause of heat build-up and nuisance tripping years later. |
| Distribution board | Metal or FR-PVC enclosure, correctly rated bus-bar, spare ways left for future circuits | A board built to today's exact load has nowhere to go when you add an AC or a solar inverter. |
| Protection | Schneider / Legrand / Havells-class MCB per circuit plus an RCCB on the incomer | The MCB protects the wire from overload; the RCCB protects the person from leakage — they do different jobs. |
| Earthing | IS 3043 earthing pits, resistance-tested, with equipotential bonding to all metal enclosures | An earth fault has nowhere safe to go without a tested, low-resistance path back. |
| Switches & sockets | ISI-marked modular accessories rated to the circuit they sit on | A 6A socket wired for a 16A load is a heat source waiting for a fault. |
| Surge protection | SPD fitted at the incomer where solar, pumps or sensitive equipment are on the same board | A single lightning-induced surge can take out every appliance on an unprotected board. |

05 / Why us
Why electrical work goes wrong — and how we avoid it.
Measured, not swapped
Tripping and leakage complaints are traced with instruments and a load schedule — not by replacing parts until it stops.
IS-standard workmanship
Correct ratings, proper terminations, tested earthing — the parts nobody photographs.
A handover sheet you keep
Test readings written down, circuits labelled, so the next electrician inherits a documented installation.
06 / Continue the current
The rest of the spine.

Solar Solutions
Rooftop generation designed against your actual load, not a brochure size.
See scope03 / INDUSTRIAL
Industrial & Commercial
Three-phase installations for sheds, workshops, showrooms and plants.
See scope04 / LIGHTING
Lighting Solutions & Maintenance
Lighting that is planned for lux and lifespan — and kept running after handover.
