About the Project
In horizontally spread residential developments the governing factor is not the number of storeys but distance. Blocks sit tens of metres apart, while landscape, car park and amenity loads are scattered across the site. This calls for a distribution architecture segregated per block rather than long feeders from a single central board.
At Sinpaş Park Yaşam the common-area loads are collected on a dedicated branch so that site management can monitor them independently. Landscape lighting, irrigation pumps, car park ventilation and amenity loads are protected separately, so the loss of one branch does not affect the others. The high number of dwellings makes meter accessibility a decisive design criterion.
Devpan Scope and Switchboard Architecture
The Devpan scope reaches from main distribution at the transformer outgoing side to the block metering panels. One switchboard standard is applied across the site, with all block boards built to the same enclosure and labelling convention.
- Main distribution boards (DevPanel): 2,500 A class, 65 kA / 1 s withstand, with bus coupler arrangement.
- Block and floor sub-distribution boards (DevBox): Sub-distribution stage at block entrances collecting meters and consumer outgoing ways.
- Power factor correction (DevComp): Automatic stepped compensation with 7% detuned reactors and small steps.
- Landscape and common area panels (DevPower): Pathway and garden lighting, irrigation, car park and emergency lighting circuits.
- Common area metering: A dedicated measurement branch reporting management consumption independently.

Project-Specific Engineering Topics
Voltage drop on long feeders
Because of the distance between blocks, cable cross-sections are selected against the voltage drop limit rather than current-carrying capacity. Sub-board positions are optimised around the supply quality of the most remote block.
Segregating common area loads
Landscape lighting, irrigation and amenity loads are collected on separate branches. This both limits the impact of a fault and allows management costs to be reported transparently.
Degree of protection for outdoor panels
Where landscape and car park panels sit in the open, the degree of protection is raised; gasket arrangement and cable entry sealing are selected for rain and dust conditions.
Meter access and change of occupancy
Metering panels are positioned at block entrances so that readings and interventions remain quick during changes of occupancy, with labelling standardised across the whole site.
Frequently Asked Questions
How is distribution organised in low-rise residential developments?
A two-stage architecture is used: a central main distribution board and a dedicated sub-distribution board for each block. Because the distance between blocks is long, cable cross-sections are selected against voltage drop and sub-board positions are set by that calculation.
What installed power does a development of this scale require?
A residential development of this scale has an installed power of approximately 4,800 kVA, with a typical transformer configuration of 3 x 1,600 kVA. The main busbar is rated at 2 x 2,500 A with a short-time withstand current of 65 kA / 1 s.
Why is common area consumption metered separately?
Because management costs are apportioned among the dwellings. When landscape lighting, irrigation, lifts and car park ventilation are collected on a dedicated measurement branch, cost allocation becomes transparent and abnormal consumption is spotted quickly.
