Akfırat, Tuzla

Akfırat, in eastern Tuzla, holds villa estates alongside logistics warehouses and plant buildings. On large plots the runs from the main board to garden lighting, a gate motor and a well pump can exceed a hundred metres; at that length an undersized conductor drops voltage at the far end, the pump motor labours and its winding overheats. The calculation follows run length, drawn current and permitted percentage drop, and in practice these distances need 4 or 6 mm².

In warehouse and plant boards, when the many high-bay luminaires and the forklift charging points share one leg, that leg saturates on the evening shift. Our crew splits lighting, sockets and the charging group onto separate legs and fits the charging circuit with a 30 mA Type B residual current device able to detect DC components. On the villa side, open elevated ground makes lightning a real exposure; a Type 1 arrester goes at the building intake, a Type 2 in the board, and earth resistance is measured and documented.

In Akfırat, heavy crystal and architectural luminaires are often hung from an old plaster plug or the junction box hook in the ceiling. Even if that fixing carries the static load it loosens under vibration and risks falling; before installation the ceiling structure is checked and a heavy-duty steel expansion anchor set into structural concrete. On plasterboard the load is never taken by the board itself but transferred to the carrying profile or the slab above.

LED spot drivers and dimmer modules buried in unventilated ceiling voids overheat, burn out and give off a scorched odour. They are relocated to an accessible ventilated recess and replaced with original, surge-protected drivers. In Akfırat installations with no neutral at the switch box, fitting a smart switch makes LED lamps glow faintly while off because of ghost current; the lasting fix is pulling a neutral from the nearest junction box, as a bypass capacitor is only a temporary patch.

If a concealed run in Akfırat breaks or starts leaking, there is no need to chase the wall end to end. The fault is first narrowed branch by branch at the board, then the route is followed from the surface with an inductive cable tracer and a FLIR thermal imager. A terminal heating under load shows as a clear hot spot on the thermal image and the area to be opened drops to centimetre scale.

Where the leakage is in an under-screed or underground run, a cable fault locator usually narrows the point to within a metre and only that area is opened. If the existing conduit is sound the cable is renewed along the same route with a draw wire; if the conduit is crushed, fire-retardant surface trunking is used. Where breaking is unavoidable its extent and cost are reported in writing first, and nothing is cut at a Akfırat address without approval.
