Certificate of Compliance

Extract from Notice R2920 (Government Gazette October 1994)

VISUAL INSPECTION

SATISFACTORY

 

Do all the components of the installation conform to the applicable standards or have they been authorised?      
Have all the components been correctly selected, installed and suitably rated?      
Have any components visible damage?      
Have fire barriers been erected or have other precautions been taken against the spread of fire or the harmful effects of heat?      
Are the conductors of the correct current carrying capacity?      
Are the protective devices of the correct size and capable of withstanding the prospective fault level?      
Are disconnecting devices to electrical equipment correctly located?      
Are different circuits separated electrically?      
Are the connections of all the conductors, including earthing and bonding, mechanically sound and electrically continuous?      
Have circuits, fuses, switches, terminals, earth leakage devices, circuit breakers, etc been permanently marked or labeled?      
Have the loads been evenly distributed across the three phases in a 3-phase system?      
Does the installation comply with the requirements of the Machinery and Occupational Safety Act, 1983 and SABS 0142 code?
