Frequently Asked Questions (FAQs)

Key questions regarding turn-key electrical contracting, switchgear manufacturing, statutory approvals, and testing protocols.

A turn-key electrical contracting solution from SSB Engineering Services encompasses end-to-end execution: pre-construction CAD drawing submittals, ETAP power flow & short-circuit calculations, HT/LT cable laying, high-voltage utility substation erection, building MEP wiring, ELV fire alarm & BMS integration, Megger/thermography testing, and obtaining statutory electrical inspectorate grid approvals.

Arc-flash analysis calculates the thermal incident energy resulting from electrical short-circuit faults. Performing ETAP power system studies helps engineers prescribe mandatory PPE safety levels, calculate arc-flash boundary distances, and tune protective relay tripping parameters per IEEE 1584 and NFPA 70E codes to prevent arc-blast injuries and plant equipment damage.

According to IEEE 80 and standard electrical inspectorate codes, the overall earthing pit grid resistance for high-voltage (HV) and medium-voltage (MV) substations must be 1 Ohm or less (≤ 1 Ω). This guarantees rapid fault current discharge, surge arrestor dissipation, and step-and-touch voltage safety for operating personnel.

Power Control Centers (PCC): Designed for main incomer distribution from transformers or diesel generators, utilizing high-ampere Air Circuit Breakers (ACBs) or MCCBs up to 4000A.
Motor Control Centers (MCC): Tailored specifically to feed and control heavy industrial induction motors using Variable Frequency Drives (VFDs), soft starters, star-delta contactors, and protective thermal overload relays.

Prior to grid energization, SSB Engineering performs: 1. Megger / Insulation Resistance Testing: Checking cable insulation integrity at 1kV/2.5kV/5kV.
2. Primary & Secondary Current Injection Testing: Validating protective relay trip times.
3. Infrared Thermography: Scanning live busbars for loose joints or hotspots.
4. Earth Pit Resistance Measurements: Validating soil ground grid resistance (≤ 1 Ω).

SSB Engineering Services offers end-to-end IT solutions including modern responsive website design, custom iOS/Android mobile app development, Enterprise Resource Planning (ERP) software tailored for contractors & manufacturers, B2B Customer Relationship Management (CRM) systems, cloud hosting, and Industrial IoT integrations.

A custom ERP system streamlines inventory tracking, BOQ costing, project milestones, and technician scheduling, while a dedicated B2B CRM automates quotation generation, lead pipelines, client status tracking, and SLA maintenance ticket handling.

ATEX and IECEx standards govern electrical installations in explosive atmospheres (refineries, gas plants, fuel depots). Equipment installed in hazardous Zone 0, 1, or 2 must be certified flameproof (Ex d) or intrinsically safe (Ex i) to prevent sparks or thermal ignition of flammable gases.

For home automation, we utilize KNX, DALI, Zigbee, and Z-Wave protocols for lighting and climate control. For industrial automation, we implement Modbus RTU/TCP, Profinet, Ethernet/IP, and SCADA OPC-UA protocols for PLC communication.
