Entrepreneurship, Estimation and Consumer Service
Entrepreneurship, Estimation and Consumer Service
Entrepreneurship, Estimation and Consumer Service tests the business side of an electrical contractor: costing, quotation, estimation, documentation, warranty and consumer rights.
Core rules and concepts
- Costing includes materials, labour, transport, tools, overheads and profit. A quotation should state scope, make and rating of materials, taxes such as GST, warranty, payment terms and validity.
- Estimation uses measured lengths and counts: number of points, average wire run per point, accessories, conduit, boxes and labour per point. Add wastage, often 5–10%, and include earthing.
- Consumer service: attend calls on time, explain the fault, give a written bill, honour warranty, keep service records and follow consumer protection law. Do not make false claims about official approval.
- A small workshop needs a market survey, pricing, record keeping, safety compliance and basic marketing.
Worked example
Estimate a 6-point lighting circuit with an average 10 m run per point. Wire length = 6 × 10 = 60 m; add 10% wastage = 66 m. At ₹25/m, wire costs ₹1650. Six switches and holders at ₹80 = ₹480; boxes and conduit ₹600; labour 6 × ₹120 = ₹720. Subtotal = ₹3450; add 10% overhead and 15% profit = ₹3450 × 1.10 × 1.15 = ₹4364; add GST as applicable. Reasoning: estimate quantities first, then price, then apply overhead and profit.
Traps that cost marks
- Quoting only material cost.
- Forgetting earth wire and wastage.
- Omitting GST or warranty terms from a quotation.
- Giving a verbal estimate with no written scope.
