Three Essential Electrical Masterclasses

Master these three fundamentals to ensure your electrical installation is durable, safe, and cost-effective.

01Cable Standards & Fire Safety

Identifying Pure Copper Cables & Preventing Electrical Fires

Undersized copper-clad aluminium (CCA) wires cause silent overheating and are the leading cause of building fires in Lagos. Learn how to verify authentic Coleman & Nigerchin cables before installation.

Spot the difference between virgin annealed copper and brittle copper-clad aluminium.
Exact gauge rules: 1.5mm² for lighting, 2.5mm² for power rings, 4mm²–6mm² for high-draw ACs and pumps.
The coil weight and factory embossing test to ensure you never pay for counterfeit reels.

02Solar & Inverter Architecture

Calculating Real Daily Watt-Hour Loads Before Buying Inverters

Avoid buying undersized inverter systems and dying battery banks. Discover how to calculate peak surge wattage versus continuous running load, and why LiFePO4 lithium outlasts tubular gel batteries.

Audit inductive startup surges: AC compressors and water pumps draw 3x–5x their rated wattage at startup.
Lithium LiFePO4 advantages: 4,000+ deep cycles at 90% DoD versus 1,200 cycles on lead-acid.
Proper DC surge protection and clean isolator disconnects to prevent board burnouts.

03Conduit Piping & DB Protection

Concealed Conduit Piping & Distribution Board Standards

What every site supervisor and homeowner must inspect before walls are plastered. Learn the danger of diagonal chasing, why ACs require dedicated radial circuits, and how RCBOs prevent fatal shocks.

Orthogonal wall chasing: Only cut straight vertical and horizontal runs to preserve structural masonry.
Human protection: Mandating 30mA Residual Current Circuit Breakers (RCCBs) on all socket rings.
Pre-plaster testing: Conducting continuity and insulation resistance tests before closing up conduits.
