About the Project
In large Dubai housing communities, air conditioning dominates consumption. On summer afternoons, when outdoor temperatures approach 45 °C, compressors across the site draw load almost simultaneously, creating a sharp peak on transformers and main busbars. In multi-block developments cable runs become long, so voltage drop and prospective fault levels have to be calculated separately for each block. Pools, gyms and shared amenities add their own distinct load profiles on top of the dwellings.
For a community of this scale, the typical solution is four 1,600 kVA transformers fed at 11 kV and two independent 3,200 A main busbar sections. Load is balanced across the blocks, while a coupler breaker allows load transfer during maintenance. Generators of approximately 2 × 1,250 kVA carry life-safety and common-area loads. Form 4a – 4b segregation protects service continuity, and DevComp panels balance the reactive power drawn by the cooling load.
Devpan Scope and Switchboard Architecture
Devpan’s scope covers LV distribution from the substations to block intakes, floor boards and common areas.
- Main distribution boards (DevPanel): typically 2 × 3,200 A, 65 kA / 1 s, Form 4a – Form 4b, with coupler and generator changeover.
- Block and floor boards (DevBox): metered sub-distribution at each block intake and on every floor.
- Power factor correction (DevComp): automatic stepped compensation sized for air conditioning loads.
- Lighting and power panels (DevPower): control of internal roads, landscape, pool and car park lighting.
- Standby supply: transfer of lifts, fire systems and common-area loads to approximately 2 × 1,250 kVA of generation.

Devpan Products Used in This Project
Project-Specific Engineering Topics
Cooling-driven peak load
Peak demand is analysed for summer conditions, and transformer and busbar ratings are chosen to cover simultaneous compressor operation.
Long cable runs
Voltage drop and fault currents are calculated for each block feeder to set protection correctly.
Block-level selectivity
Selectivity between the main board and block intakes keeps a fault in one block from affecting the others.
Common-area automation
Landscape and pool lighting run on timer and photocell control to cut energy use.
Frequently Asked Questions
What is the installed power of Dubai Land Residential Complex?
For a residential community of this scale the installed power is approximately 6,400 kVA, with a typical transformer configuration of 4 × 1,600 kVA. The main busbars are typically planned at 2 × 3,200 A and 65 kA / 1 s, with 11 kV medium voltage and around 2 × 1,250 kVA of standby generation.
How is distribution planned in a multi-block community?
Each block gets its own feeder from the main board, with an incomer and metering at the block intake, so maintenance and faults can be managed block by block.
How does a hot climate affect switchboard selection?
Electrical rooms are air conditioned, busbars and breakers are temperature-derated, and outdoor boards use enclosures resistant to solar radiation.
