The Low Voltage Directive ensures that electrical equipment within certain voltage limits provides high level of protection for it's users. The Directive covers electrical equipment with a voltage between 50 and 1000 V for alternating current and between 75 and 1500 V for direct current. These voltage ratings refer to the voltage of the electrical input or output, not to voltages that may appear inside the equipment. For electrical equipment within its scope, the Directive covers all health and safety risks, thus ensuring that electrical equipment is safe in its intended use.
There are a small number of exclusions from this Directive, which are generally products covered by more specific directives. ICASA requires that you do Safety testing before you apply for Type Approval. The applicable standard is SANS / IEC 60950-1.
