Şişli

In Nişantaşı and Teşvikiye the ceilings are high and the drop from the rose to the board is long. Flats of the 1950s and 1960s still have two-wire NYA sockets and a thin lighting pair. An earth may never have been pulled. The ground floor is a boutique or a shop with a window, not a night bar. Track spots and window transformers were added later onto the dwelling column. When the window lights in the evening, the neutral screw of the flat above heats. The heat may not open the phase breaker, because the load is on the neutral. Even when the call arrives as a burnt socket, the first place looked at is not the cover but the neutral bar at the flat intake. Which screw of the bar goes to which floor is written down. A loose screw is tightened and a blackened NYA tail is cut back to sound copper. The tightening does not crush the conductor. The load is read with a True-RMS clamp, once with the window on and once with it off. If the phase current is ordinary and the neutral current is high, the fault is the residual the window transformer has parked on the neutral. The ampere rating is not raised. A 1.5 mm² lighting pair does not go above 16 amperes. The window leaves the dwelling socket on the board after the meter.

If a washer chassis shocks in an old flat, the cause is a missing earth, not the heat of the neutral. A two-wire socket has no protective conductor. If the chassis was bonded to a heating pipe, the pipe is not accepted as an earth. The plug comes out. If there is no 30 mA Type A residual-current device, the board is written ahead of a window bulb. The device is not bridged. If electronic residual from the office floor and the cloth or tired NYA insulation of the dwelling gather on the same device, the device drops at night. The lines are separated with a 500 V megohmmeter. The computer, the television and the window transformer come off their plugs before the test so the test voltage does not reach a board. A dwelling branch under one megaohm is not landed on a new breaker until it is renewed. If a cloth conductor crumbles in the fingers, that room goes into halogen-free trunking along the architrave, and the high ceiling is not chased. Plaster and cornice are not broken for the trunk. Joints inside the trunk stay in boxes. A Schneider or Siemens DIN breaker is chosen with a breaking capacity matched to the board. The cooker, the washer and the air conditioner are not left on the same 16 ampere way.

On a Mecidiyeköy office floor there are many switch-mode supplies on the same phases. The third harmonic and its multiples add together on the neutral. The phases can look balanced while the neutral carries more current than one phase. This is not a factory busbar. A desktop computer, a screen, an LED driver and a small uninterruptible supply are the load of an office floor. The measurement is made on the neutral conductor, under load, with a True-RMS clamp. The clamp must close fully around the neutral and must not miss half of it. If the neutral current is above the phase current, the neutral bar and the section of the neutral conductor are written down. If the section is short, the office neutral after the meter is enlarged, or the office neutral is separated from the dwelling neutral. The service neutral ahead of the sealed meter is not ours to enlarge. If that side is hot, the report goes to BEDAŞ. The rating of the phase breaker is not raised to cool a hot neutral. Raising it leaves the thin neutral with still more residual. Phase-to-neutral voltage is written on the same paper. If the voltage is ordinary and the neutral current is high, the fault is separate from a loose neutral. If the two are mixed, the wrong screw is tightened in the name of a flaring lamp.

On the office floor a 30 mA Type A device stays in place for the pulsed leakage of switch-mode supplies. The threshold is not raised. If the small leakages of a floor full of supplies add up and drop the device, the lines are split into groups and each group is written to its own device. A bridge leaves the office socket without protection. Changing the device without grouping brings the same trip back the next morning. A 500 V megohmmeter reads branch insulation after the supplies are unplugged. Low insulation is not waved through as harmonics. The two are separate lines. If a screw on the neutral bar is loose, it heats even without harmonics. The screw is tightened and the current is read again. If the current is still high, the cause is section and harmonics, not looseness. The chassis leakage of an uninterruptible supply is also separated with the clamp, not along a chassis wire, but on the supply neutral and phase of the unit. If the chassis shocks, the plug comes out and the earth conductor is completed in halogen-free trunking. The office earth is not left on a heating pipe. A heavy industrial motor is not looked for on this floor and it is not written down.

When an office floor opens beside or under a Nişantaşı apartment, a commercial riser may have been pulled next to the old dwelling column. The two can look like one shaft and they may have been landed on the same neutral bar. The office harmonic current then heats the dwelling neutral. The lamp upstairs settles when the office day ends and flares again in the morning. The caller blames the flat socket. The split is made on the board after the meter. The office phases and the office neutral go onto their own bar. The dwelling phases stay on their own bar. A neutral bridge is not left between the bars. A label states which conductor goes to the office and which goes to the flat. If there is no label, two readings are taken with the clamp, once while the office floor is under load and once with the load off. The conductor whose neutral current falls when the load falls is the office. The conductor that does not fall is the dwelling. This split does not open the cover of the sealed meter. If the common service cable ahead of the meter is hot, the line goes to BEDAŞ and to the manager together. The manager's note has the floor, the phase and the neutral amperes. The note is not written as a factory survey. The place written down is an office floor and a dwelling floor.

The office Cat6 is not clamped to the power riser. Data that runs beside the power line the length of the corridor both picks up noise and gets joined by mistake to the lighting pair. Cat6 is pulled in its own halogen-free trunk. The trunk does not break the cornice of the dwelling stair. Room and socket numbers are written at the ends. The RJ45 is proved with a cable tester. It is not left because a screen came on. A camera supply is not taken from the lighting pair. The lighting pair in a Nişantaşı corridor is thin NYA and it is switched. The camera adaptor heats that pair. The adaptor is fed from the office or flat board after the meter, on its own fuse. If a short power tail that leaves for an outer court will get wet, NYY is used. NYY is not fitted in place of Cat6. The two cables are not crushed in one grip. If a window on the office floor runs through a dimmer, the dimmer stays on a way apart from the camera and the computer sockets. The dimmer's leakage should not drop the 30 mA Type A device together with the office group. When the job ends, the paper keeps which bar was separated and which Cat6 end passed the test.

The 2026 bands are labour excluding materials, and in Şişli they move on site. Fault finding sits in the 750-1,500 TL band. Reading the neutral and the phase apart with True-RMS, and a 500 V megohmmeter test, sit inside that band. A breaker or residual-current device sits in the 1,250-3,200 TL band. A 30 mA Type A device split onto an office group, and a Schneider or Siemens DIN breaker, enter that band. A socket or a light sits in the 650-2,800 TL band. A single Nişantaşı socket and the separation of a window transformer are not written as one item. An air-conditioning circuit sits in the 2,400-5,500 TL band. An air conditioner is not added later onto an old 16 ampere way. A flat board sits in the 6,500-16,000 TL band. An old apartment board whose neutral bar has carbonised is what that band covers. Separating the office bar from the dwelling bar is not a renewal of a whole estate, and it is not priced as a factory board. The survey fee comes off the job if the repair is accepted. The binding figure is written after measurement and before work starts. Workmanship is guaranteed for one year. NYA, NYY, halogen-free trunking and Cat6 sit outside as materials. The service neutral at the sealed meter does not enter these bands.

A Şişli call is written in the appointment book. A burning smell, arcing or a shock is placed at the head of the same day. If there is no smell and no shock, the neutral measurement stays on the appointment day that was named. Traffic coming down from the bridge toward Mecidiyeköy is not written in this book as a minute figure. The technician states any tariff difference on the phone before setting off. The book records whether the address is a Nişantaşı apartment or a Mecidiyeköy office, whether the meter seal is in place, whether the neutral is hotter than the phase, and whether the device is bridged. An industrial board change is not promised on missing information. When the job ends, the paper keeps the neutral amperes, the phase amperes, which bar was separated, and the test button of the device. The one-year workmanship guarantee belongs to that job. The term does not grow because of a wait on the bridge. If the bell transformer is hot, the bell circuit leaves the socket circuit. A camera is not piled onto the entry-phone pair. A survey item is not opened as if the office floor had a production line. If the meter cover is warm and the seal is intact, the company is called, and the flat or office board stays on its own line the same day.
