Başakşehir

On the Kayaşehir stages the first board was arranged for a resistive cooker and a single air conditioner. When the owner later fits an induction hob, that load is added to the phase the living-room unit already occupies. If the dishwasher was left on the same way, L1 approaches thirty amperes in the evening and L2 and L3 stay in single figures. Before this picture is called a transformer fault, two points are written down. The first is the output of the sealed meter. The second is under the flat's main breaker. If the meter output is sound on all three phases and the sag is only inside the flat, the pile-up is after the seal. If all three phases are low in front of the meter cover, the report goes to the distribution company. We do not open the seal. The instrument is a True-RMS clamp. An average-responding clamp writes low on a harmonic neutral and makes the stage board look healthy. The reading is taken under load. Zero amperes in an empty flat is not a diagnosis.

The hob circuit leaves the socket branch. The NYM section in the wall is measured. If the section cannot carry the load, the conductor is renewed. If the section is enough, only the phases are redistributed, and the breaker rating is not increased on paper. An induction hob and an inverter air conditioner produce pulsating direct residual current. A Type AC device can be blind to that residual. Flat sockets and the hob circuit are protected with a 30 mA Type A residual-current device. A bridged device is removed. The bridge is not left as a diagnosis. The Schneider or Siemens rail already standing in the estate main board is followed. A sound enclosure is not broken just to change the brand. If the feed between blocks is NYY, it stays in the duct and is not mixed with the NYM inside the flat. Hospital compensation and a shopping-mall transformer are not the subject of this visit. The paper that is written is the stage, the block, the floor and the amperes of the three phases.

In one Kayaşehir stage, hundreds of LED drivers, phone adapters and inverter air conditioners return to the same neutral bar. Triplen harmonics do not cancel in the neutral. They add. Neutral current can exceed the current of the heaviest phase. An average-responding clamp shows that low. A True-RMS clamp writes the neutral and each phase separately. If the neutral-bar screw is loose, contact resistance rises, the bar heats, and lamps flare in one flat and die in the next. This is not the same sentence as an open neutral on old cloth cable. Here the conductor is new, the common bar is thin, and the stage was gathered on one screw. The screw is tightened. If the section is short, the neutral conductor is enlarged. The heat is not hidden by enlarging a phase breaker. How many neutral amperes were read in which block is left in writing with the manager.

The common estate board carries the booster-pump contactor and the generator transfer switch. The generator is not started because a flat lamp went out. Which source the transfer switch is fed from is written down, and the side before the meter seal is a separate line. If the pump has lost one phase, the motor heats. The missing phase is shown at the contactor output with a True-RMS clamp, and the motor is not blamed before that reading. The intercom bus and the camera supply are not left on a socket way of this common board. A separate branch is pulled for the cameras, so the recorder does not carry the kitchen phase's neutral heat. Cat6 ends are proved with a cable tester. An end left because the picture came up once drops the recorder the following week as well. If the in-stage duct is closed, the camera cable does not go through finished plaster. It goes through the existing shaft or halogen-free trunking.

If the BEDAŞ seal is intact and the meter body is cold while the voltage is unbalanced only inside the flat, the riser terminal and the flat board are measured. If the seal is already broken, or the meter side is warm, a company report is opened. We do not imitate a seal. The riser belongs to the building. Blackening inside one flat's cover is a sign that the common screw on the same floor may be loose as well. The note left with the manager carries the stage name, the block, the phase colour and the amperes. The flat owner does not have that screw undone alone. The generator room and the estate transformer's cubicle are a locked area of the distribution company or the estate operator. If there is no key, that door is not forced. Our boundary is the conductor from the meter output to the socket.

A Başakşehir call is tied to an appointment time. A burning neutral, a terminal that arcs and a chassis that shocks are written at the front of the same day. No minute figure is set for the barrier, the car-park barrier arm or the one-way road inside the stage. Before setting off, the technician separates on the phone whether measurement and repair will finish in the same visit. The 2026 labour band excludes materials and narrows on site: fault finding 750-1,500 TL, a breaker or a 30 mA Type A device 1,250-3,200 TL, a socket 650-2,800 TL, a dedicated hob or air-conditioning circuit 2,400-5,500 TL, a flat board 6,500-16,000 TL. NYM, the rail and the device body sit outside that range. The survey comes off the labour if the repair is accepted. The binding amount is on paper after the phase currents are written and before work starts. Workmanship on the joints we make is one year. A hospital or shopping-mall board is not folded into this band.

In most blocks the stage intercom is fed from a socket in the weak-current room. That socket is on the same phase as the kettle circuit in the security cabin. When the kettle and the induction hob draw together, the intercom transformer heats, the door does not release, and the screen in the flat goes dark. If the transformer body is warm, the intercom leaves the socket branch and is put on its own thin pair. A camera adapter is not added to that thin pair. The cameras have their own breaker, the intercom has its own breaker, and the kitchen is a third way. The three are not placed behind one 16 ampere breaker. An adapter fault then does not drop the hob and the door speech together. The ends are labelled. Without a label the next crew ties a kettle to the same socket again.

If the weak-current room is damp, the adapter body sweats and a 30 mA Type A device can trip at night. The device is not bridged. The adapter is moved to its own way, and the socket circuit's insulation is read with a 500 V megohmmeter when that is needed. A branch under one megaohm is not connected behind the new device. The new device would feed rotten insulation and it would trip again. This reading is made in the estate's own weak-current cupboard, not in a hospital room. The cupboard is opened with the manager. When the measurement is finished the cover is closed, and a temporary extension lead is not left in the cupboard. An extension left behind is next month's smell of fire.
