Mumbai electrical appointment guide

What an electrician does and where the job hands over.

An electrician plans and installs the wiring behind your walls and ceiling. That covers the distribution board, circuit breakers, earthing, conduits, wires, switch and socket boxes, fan and light points, and the final fixing of switches, sockets and fittings. Many also install ceiling fans, geysers and inverter wiring. Cutting and closing wall chases sits with the civil contractor, and the false ceiling team fixes the frame that the lights hang from. Air conditioning installers usually run their own copper pipe but need the electrician to give a dedicated point. The carpenter must leave cutouts and cable routes inside wardrobes and kitchen units. Ask each electrician to list which points, appliances and connections are excluded.

How to vet an electrician before you pay.

Ask for the GST registration of a firm and match its name to the quotation and the bank account. For a sole proprietor, ask for a PAN and Aadhaar copy. Ask whether the contractor or the wireman holds a licence or permit from the state electrical licensing board and ask to see it, because some society and utility processes need a licensed contractor to sign. Visit a flat wired at least a year ago and ask the owner about tripping, warm switch plates and whether the layout drawing matched what was built. Ask to see a distribution board the contractor finished, with circuits labelled. Meet the wireman who will actually do your work and ask how many years he has done concealed wiring in occupied buildings.

What a proper electrical quotation contains.

Electrical work is quoted by the point, so the quotation must define what one point includes, such as the conduit, wire, box, switch and the run length allowed. Points for lights, fans, sockets, air conditioners, geysers and the kitchen should each be listed with a quantity. The quotation must name the wire brand, the copper size for each circuit type in square millimetres, the conduit type, the switch and socket brand and range, and the breaker brand and ratings. It should state the number of circuits and whether an earth leakage device is included. Inclusions such as the main board, the earthing, testing, cable for the meter to board run, and debris removal should be clear. Tax should be a separate line. Ask for a written warranty on workmanship and a payment plan tied to inspected stages.

Common frauds in electrical work.

The trick with the worst consequences is undersized wire, where a smaller copper cross section is used than quoted, often with a printed marking that still looks right, so check the wire against the coil label and the brand's own catalogue. Aluminium or copper clad wire is passed off as copper. Fake or copied ISI marks appear on wire coils and switches, so buy from an authorised dealer or check the BIS licence number on the BIS website. Point counts are padded by splitting one point into two on the bill. Fewer circuits are run than quoted, so several rooms trip together. Joints are hidden inside conduits instead of in boxes, which you cannot see once plastered. Earthing is skipped or connected to a water pipe. Old wire is left in old conduits and billed as new.

When to hire an electrician directly.

Hire directly when the job is a repair, a few new points or a rewire in an otherwise finished flat, and you can be present for the open wiring stage. You then coordinate with the civil contractor for chases and with the false ceiling team for light cutouts, and you carry the risk if a conduit is buried before the wire is pulled. Hire through an interior or turnkey contractor when the wiring is part of a full fit out with new ceilings, kitchen and wardrobes. That contractor then fixes the sequence, owns the drawing and gives one warranty across trades. The usual clash is a light point that does not line up with the ceiling design or a socket hidden behind a wardrobe. Ask who pays to move it.

Sequence, dependencies and site checks during electrical work.

Before work starts, agree a point layout drawing marked on the floor plan, with switch heights and socket positions in each room. Conduits go in after civil chasing and before plaster, so inspect every conduit route while open and photograph it against the drawing. Check the wire coils on delivery for brand, size, batch and the BIS mark, and count them. Wires are pulled after plaster and before painting, so ask to see the colour coding for phase, neutral and earth in every box. Before the false ceiling is closed, photograph the ceiling conduits and junction boxes. At the end, ask for an insulation and earth continuity test in front of you, and for each breaker to be labelled on the board. Keep the drawing updated with any change.

Payment, handover and warranty closure for electrical work.

Keep the advance small and release it when wire, conduit and boxes arrive on site and match the quoted brands and sizes. Release the second payment after all conduits are laid, photographed and approved before plaster. Release the third after wires are pulled and the distribution board is fitted. Hold the last payment until every switch and socket works, the board is labelled, the earth is tested and the drawing is corrected to show what was built. At the end, collect the as built layout with circuit numbers, the invoices for wire and switches showing brand and size, the test readings in writing, spare wire and switches left over, and a written warranty with a start date. Get a signed note that no dues remain.
