The document discusses regulations for electrical supply systems and drainage systems in buildings according to Malaysian law. Regulation 15 specifies that electrical apparatus must be constructed or protected from weather, water, corrosion and other hazards. Regulation 16 requires switches, circuit breakers and fuses to safely interrupt electric currents that exceed safe levels. Regulations 54 and 56 address requirements for stormwater drains to be emptied safely and not used to carry soil or wastewater. Pipes carrying rainwater must also not serve as ventilation for drains.
