Electrical supplies online: selling wires, switches and breakers on specification and approvals
What an electrician or contractor checks before buying wires, modular switches and MCBs online, how to list each on its printed specification and marks, and where a listing must stop and leave the advice to an electrician.

An electrician on a site in Whitefield types "1.5 sq mm FR wire 90 m red" into a phone and opens your listing. It says "premium quality copper wire, long lasting, best price". The electrician goes back to the counter they already use. Electrical supplies sell online on the specification the manufacturer prints: size, conductor, insulation type, rating, poles, breaking capacity and the certification marks on the pack. List exactly that, photograph the markings on the item you ship, and stop short of advice on which size or rating a circuit needs. That call belongs to the electrician doing the job.
Who is buying, and what each one types
Three kinds of buyer read an electrical listing differently.
The electrician knows what they want before searching, and types sizes and codes: "6A one-way switch" with a range name, "32A DP MCB C curve". If the title does not carry those words they do not find you, and if the page does not confirm them they do not trust you.
Contractors buy the same items in bulk for a project. They want a GST invoice in the firm's name, a price for the whole list and dispatch to site. A cart built for one coil at a time is in their way.
A homeowner buys what the electrician wrote on a slip of paper, or replaces one broken switch, matching the photo to what is on the wall. For them, the range name and the plate colour matter more than any rating.
What to put on each listing
| Product | What the buyer checks | Put in the title | Photograph | Never write |
|---|---|---|---|---|
| House wire | Size in sq mm, copper strands, insulation (PVC, FR, FRLS, HFFR), voltage grade, coil length, colour | Brand, size, insulation, length, colour | The printing along the insulation, the coil label | "Suitable for AC" or any load claim |
| Modular switches and sockets | Current rating, one-way or two-way, module size, range, colour | Range name, rating, function, module size | The back of the module with its ratings | "Fits all plates" |
| Plates and boxes | Module count, range, finish, box depth | Range name and module count | Plate front and back, box with dimensions | "Compatible with any brand" |
| MCB | Poles, current rating, tripping curve, breaking capacity | Poles, rating, curve | The front face with every marking legible | Which rating to fit for a room or appliance |
| RCCB | Sensitivity in mA, poles, current rating, type | Sensitivity, poles, rating | The front face and the test button | "Protects your family" |
| Distribution board | Number of ways, single or three phase, flush or surface | Ways, phase, mounting | The inside, with the knockouts | A suggested layout for the buyer's home |
The last column is where listings get into trouble. A line such as "ideal for geysers" is circuit advice. The wire a geyser circuit needs depends on the load, the length of the run and how the wire is laid, and only the person on site knows those. Write what the product is. Leave what to connect it to for the person doing the job.
Why modular switches come back
Modules and plates belong to a range. A brand sells several ranges, and a module from one range will not always sit in the plate of another, even when the colour and the brand match. Buyers do not know this. They see "white 6A switch" with a brand name and order it for a plate already on the wall.
So name the range in every title, and put "fits [range] plates" in the first line of the description. The plate listing gets a short list of the modules it takes. When a buyer is replacing one module, ask for a photo of the plate before you dispatch. One WhatsApp message saves a return.
Approvals and marks: say what is printed, nothing more
Electricians look for the certification mark on wires, breakers and switches before anything else, because counterfeit wire is a known worry in the trade. Your listing has to show the mark printed on the product you ship, in a clear photograph, with the licence or registration details where the pack carries them.
Do not go further than the pack. Words such as "fireproof", "shockproof" or "100% safe" are claims a listing cannot support, and a buyer who relies on them is relying on you. Which products must carry a mark, and what it must show, differs by product and changes. Check the current position with your own adviser or the regulator before you list a new line.
For example: a Bhagirath Palace wholesaler goes online
Imagine a family electrical wholesaler in Bhagirath Palace, Delhi, that has sold to electricians across the counter for decades and opens its own website. To save time it lists MCBs as one product, with a dropdown from 6A to 63A and one photograph of a 32A unit for every option. The tripping curve is not mentioned. Buyers order a 16A single-pole breaker and receive a C curve when their electrician wanted B. Returns follow, and two reviews say the shop sent the wrong item.
The shop sent exactly what the listing described. The listing never mentioned the curve. Splitting the dropdown took the staff a week of photographing breakers, and the catalogue grew from one MCB page to dozens.
So the shop broke the dropdown up. Each rating and curve became its own listing, with the curve in the title, a photograph of that unit's own face and the breaking capacity in the first line. The titles now match what electricians type, such as "16A B curve SP MCB", so the page is found by the buyer who knows what they need.
Where online selling is the wrong fit
Online works for repeat, specified items an electrician can name: coils, modules, plates, breakers by rating. It is a poor fit for the homeowner planning a full rewiring, who needs an electrician to draw up the list first. Say so on those category pages, and offer to quote against the electrician's list instead. That buyer comes back with a list you can fill.
Hand one listing to an electrician
Open the listing for your best-selling MCB and show it to an electrician who buys from your counter. Is the curve in the title? Is the photograph the unit you ship? Does any line tell the buyer what to connect it to? Whatever they trip over is the pattern to correct across the range. Putting the codes electricians type into titles and filters is on-page SEO work, within our e-commerce sales and marketing group. To have the catalogue rewritten to that standard, tell us what you need.
