Electrical Installation & Finishing Process in Egypt — Step by Step

Before any cable or conduit is touched, an electrical drawing must be produced. The drawing defines the location of every outlet, switch, and lighting point; distributes circuits across the panel; and calculates loads to determine cable cross-sections and breaker ratings.

What must happen at this stage: — Review the apartment or villa architectural plan with the electrician — Decide the locations of AC units, washing machines, and ovens before work starts — Agree on the number of internet, TV, and CCTV points — Obtain a preliminary load schedule confirming that total capacity matches the unit's supply

Common error in Egypt: many electricians begin rough-in directly without a drawing. The result: outlets in the wrong locations, cables run in unnecessarily long diagonal routes, and circuits loaded unevenly.

Time required: drawing for a 120–150m² apartment = one day for the engineer. Multi-storey villa drawing = 2–3 days.

This stage is the heart of all electrical work. PVC conduits are run inside walls and ceilings, cables are pulled through them, and flush boxes for outlets, switches, and lighting points are fitted.

Realistic durations: — Apartment up to 120m²: 3–5 working days with a 2–3 person team — Apartment 150–200m²: 5–7 days — Single-floor villa 250m²: 7–10 days — Two-storey villa 350m+ : 10–14 days, or more for pools or generators

Important for villas: concrete slab conduits must be run before the slabs are poured. If concrete is poured before electrical work is done, the electrician must run conduits through walls instead of ceilings, doubling the work and raising the cost.

Owner checkpoints during this stage: — Are cables the correct cross-section and from an EOS-certified brand? — Are conduits running parallel and perpendicular inside walls (not random diagonals)? — Are flush boxes fitted flush and secure in the wall? — Is the distribution panel location fixed as agreed and easily accessible?

This stage is skipped in many Egyptian projects — a serious mistake. After cables are run and before walls are plastered, an Insulation Resistance Test must be performed using a Megger on every circuit.

What the test detects: — Crossed or touching wires inside conduits — Damaged insulation from forced pulling or sharp bends — Incorrect connections inside boxes

Acceptable result: insulation resistance above 1 megohm for every circuit.

Why this specific timing? After plastering, the cable is inaccessible without breaking walls. Early detection means a quick, inexpensive repair. Detection after finishing means demolishing part of the apartment.

Request a written report of the test results — even a handwritten note with the measured figures, signed by the electrician.

After rough-in and the insulation test, your project enters a planned electrical pause. This period is necessary and must be scheduled in advance.

Correct trade order: 1. Electrical, plumbing, and other conduit work finished first (inside walls) 2. Plastering closes the walls 3. Painting 4. Tiling and floors 5. Electrical finishing (the next stage)

Common error: the tiling contractor starts before the electrician has given final sign-off on cable routes. This happens when the owner pressures the schedule. Result: if the electrician needs to adjust a route after tiling, tiling must be broken.

Typical duration of this pause: — Apartment: 2–3 weeks (plastering and painting) — Villa: 3–6 weeks (plastering, painting, and possibly exterior work)

Summer project note: in July and August, high temperatures slow the drying of plaster and paint in lower floors and humid rooms. Add two extra days for this season.

Once painting is fully dry, the electrician returns for the final stage: installing outlets, switches, and lighting points; connecting all circuits to the distribution panel; and fitting and labelling the breakers.

What is done during finishing: — Installing the distribution panel with labelled MCB breakers per circuit — Installing RCD breakers on bathroom and kitchen circuits — Fitting all outlets and switches with earthing connections — Connecting lighting points and chandelier terminals — Installing thermostat controls for AC units if in scope

Realistic durations: — 120m² apartment: 2–3 days with a two-person team — 180–200m² apartment: 3–4 days — Villa: 4–6 days depending on floors and finishing level

Finishing checkpoints: — Is the panel from a certified brand (Schneider, Legrand, ABB, Hager)? — Is every breaker clearly labelled with the circuit it protects? — Is there a 30mA RCD on bathroom and kitchen circuits? — Are all outlets firm, flush, and sealed with no gaps in the wall?

The final stage before acceptance is testing and documentation. This stage must not be rushed.

Required tests: — Earth Resistance Test: confirms earthing resistance is 2 ohms or less — RCD Test: the test button on each RCD is pressed to confirm instant trip — Sequential circuit commissioning: each circuit is energised in turn to confirm no overload or short — Final insulation resistance test: results compared to the pre-plaster test to detect any deterioration

Mandatory handover documents: 1. As-Built electrical drawing (records actual routes of every cable and conduit) 2. Earthing resistance test report with measured value 3. Insulation resistance test reports — before and after finishing 4. Panel schedule (every breaker, rated current, circuit it protects) 5. Warranty certificate — duration and what it covers 6. Materials list (cable brand, cross-sections, breaker and outlet brands)

An electrician who refuses any of these documents is giving you a red flag — do not ignore it.

Total actual electrical working days (excluding waiting periods for other trades):

Apartment 100–150m²: — Design: 1 day — Rough-in: 3–5 days — Insulation test: half day — Finishing: 2–3 days — Commissioning tests: half day — Total electrical days: 7–10 actual working days

Villa 250–350m²: — Design: 2–3 days — Rough-in: 10–14 days — Insulation test: 1 day — Finishing: 4–6 days — Commissioning tests: 1 day — Total electrical days: 17–25 actual working days

Total project lifespan (including waiting for other trades): — Apartment: 5–8 weeks from rough-in start to key handover — Villa: 10–16 weeks (longer with pool wiring or generator installation)

Common delay causes in the Egyptian market: — Late material delivery (especially cables and specific branded switches from wholesale warehouses) — Owner indecision on outlet or switch locations — Electrical-plumbing conflict on shared walls — Delays by other trades pushing back the finishing start — Change orders after rough-in has begun (the most common source of extra time and cost)
