Switchboards & MCCs
Custom-built LV switchboards, motor control centres and distribution boards from our panel workshop — fully type-tested, labelled and FAT'd.
Electrical Engineering
LV and MV electrical infrastructure, engineered and certified.
Design, manufacture, installation, certification and ongoing care of the electrical infrastructure your operation depends on — from main intake through reticulation to the final motor terminal.
Overview
Electrical systems built for compliance, resilience and growth.
Promation SA delivers complete electrical engineering services across LV and MV environments — switchboards, motor control centres, distribution, backup power, renewable integration and protection. Every design is SANS 10142, SANS 10142-1 and IEC compliant, load-shedding-aware and sized for future expansion rather than today's load. Our in-house panel build, installation, testing and certification capability keeps the entire chain under one accountable contract — design errors do not become installation problems six months later.

Problems Solved
The operational pain we remove.
Every engagement starts with the production, compliance and cost problems that brought you to us — not a generic feature list.
Switchboards and DBs that no longer match the load they carry
Impact: Nuisance tripping, overheating, insurance exposure and the constant threat of an unplanned outage on critical equipment.
No reliable backup during load-shedding or grid instability
Impact: Lost production, spoiled stock, frozen tenants, brand damage and the cost of emergency hire generators every quarter.
Solar and battery quotes that ignore your real load profile
Impact: Under-sized systems that never pay back, or oversized systems that breach grid-tie rules and void warranties.
Out-of-date as-builts, missing schedules and expired CoCs
Impact: Failed insurance audits, blocked property sales, and electricians refusing to work without re-drawing the whole site.
Cable routes and earthing nobody has verified in years
Impact: Latent fault current paths, lift-station risk and arc-flash exposure that only surfaces during the next failure.
Energy bills rising without a clear reason
Impact: No sub-metering, no demand profile and no way to attribute consumption to tenants, departments or production lines.
Key Capabilities
What we engineer, install and support.
02
Power distribution design
Reticulation design, cable sizing, protection coordination, earthing studies and short-circuit analysis to SANS / IEC standards.
03
Backup, UPS & BESS
Generator, UPS and battery energy storage sized and integrated for true operational continuity — not just headline kVA.
04
Solar PV & hybrid
Grid-tied, off-grid and hybrid PV with BESS, designed to work alongside generators and existing supply without conflicts.
05
Energy & sub-metering
Tenant, plant and feeder-level metering with demand management, power quality logging and automated reporting.
06
Compliance & CoC
Full electrical Certificates of Compliance, periodic inspections, thermographic surveys and remediation programmes.
07
Protection studies
Discrimination, arc-flash and protection-relay coordination using SKM, ETAP or DIgSILENT — documented and approved.
08
MV infrastructure
11 kV and 22 kV ring main units, transformers, mini-substations and protection — design, supply, install and commission.
09
Maintenance & support
Scheduled inspections, oil testing, thermographic surveys, breaker overhauls and 24/7 fault response under SLA.

Benefits
Why operators choose Promation SA.
Lower energy cost
Demand management, power factor correction, sub-metering and tariff optimisation that consistently pay for themselves.
Load-shedding resilient
Hybrid backup architectures keep critical loads alive automatically — no manual changeover, no shouting at security.
Audit-ready
Complete as-built drawings, schedules, test results and CoCs — ready for insurers, regulators and prospective buyers.
Single accountability
Design, build, install, certify and support under one contract — no gap between consulting engineer and contractor.
Scalable infrastructure
Boards, busbars and cable trays sized for tomorrow's load, not just today's — avoiding the next disruptive upgrade.
Vendor-flexible
We specify the right gear for the application — Schneider, ABB, Siemens, Eaton — not the supplier with the best margin.

FAQ
Common questions.
Do you issue Certificates of Compliance?
Yes. All installations are signed off by registered electricians and a full SANS 10142-1 Certificate of Compliance is issued on completion, with supporting test schedules.
Can you work on live MV equipment?
We follow strict isolation, lock-out and permit-to-work procedures. Where live work is unavoidable we use suitably qualified specialists with ARC-rated PPE in line with regulation and our safety file.
Will my insurer accept your installation?
Yes. We provide complete documentation packs — schematics, schedules, test results, thermographic reports and CoCs — specifically designed to satisfy insurer and regulator requirements.
Can you integrate renewables with my existing supply?
Yes. We design hybrid PV / BESS / generator architectures that prioritise critical loads, comply with NRS 097 and municipal grid-tie rules, and remain safe and predictable during outages.
Do you handle municipal approvals?
Yes. We compile and submit the required NRS / municipal documentation for embedded generation, capacity upgrades and new connections, and liaise with the supply authority on your behalf.
Can you upgrade a board without taking the building down?
In most cases yes. We plan temporary feeds, phased cutovers and after-hours windows so essential loads stay live during the upgrade.
Do you maintain installations you didn't build?
Yes. We do takeover audits on legacy installations, document what is there, remediate critical defects and then maintain under a standard SLA.
How quickly can you respond to a fault?
SLA customers have defined response times — typically same-day on site within Pretoria and surrounding areas (~150km), with 24/7 telephonic engineering support and remote diagnostics where instrumentation allows.
