OpenHow to use the tools
Are these quotations?
No. Each tool is a planning sheet for a conversation at the Naini showroom. A measured drawing, the load and the Havells datasheet decide what you buy.
Which tool should I open first?
Start with the house wiring plan for points and metres. Use wire size or voltage drop for one long circuit, then send the material list on WhatsApp.
Will the page invent a price?
No. Rupees appear on the house wiring plan only after you type a rate or use the Lifeline Plus coil price already on this site. The other tools count size, length, amps and pieces.
