Common electrical panel types recommended for Nairobi properties

Common electrical panel types recommended for Nairobi properties prioritize safety, compliance with EPRA/KEBS standards (e.g., KS 1519, IEC 61439), and resilience to voltage fluctuations (220-250V single-phase, 415V three-phase). Single-phase dominates homes; three-phase suits apartments/offices.

Residential Properties (Houses, Bungalows)

Main Distribution Board (MDB/DB) – 60-100A Single-Phase

• 12-24 way MCB panels with RCBOs/RCDs for kitchens/bathrooms.

• Surge protection essential for KPLC spikes.

• Ideal: Schneider Easy9 or ABB F200 series (KSh 15k–40k).

• Why: Handles lights (2.5mm²), sockets (4mm²), geysers (6mm²); <10Ω earthing.​

Load Center/Sub-Panels

• 32-63A for detached units/garages.

• Split metering for tenants.

Apartments/Mid-Rise Buildings (3-10 Floors)

Power Distribution Board (PDB) – 200-400A Three-Phase

• Floor-mounted, Form 2b separation.

• CT metering, SPDs, 36-60 ways.

• Brands: Legrand, Hager (KSh 50k–120k).

• Features: Phase balancing (±10%), 200% neutral for harmonics.​

Tenant Sub-Meters

• Prepaid digital meters per unit.

Commercial Properties (Offices, Shops, Hotels)

Main Switchboard (MSB) – 630-1600A Three-Phase

• Free-standing IP42/55, busbar trunking.

• VFD-ready for HVAC; generator changeover.

• ABB ArTu or Siemens NX (KSh 150k–350k).

• Compliance: P.E.-stamped design.​

Motor Control Center (MCC)

• For lifts/pumps; DOL starters.

Industrial/Factory Properties

MCC/PDB – 2000A+ Three-Phase

• Form 4b segregation, withdrawable modules.

• PLC integration, harmonic filters.

• Custom: Seamless Automation builds (KSh 300k+).​

Nairobi-Specific Tips: Voltage stabilizers mandatory; clay soil needs multiple earth rods. Always use ERB-certified installers for EPRA C1/C2 forms. Upgrade old fuse boxes to MCBs for safety.
