I have received this query via the message feature for submission to this forum:

Good day
We have recently replaced all the CFL fittings with LED fittings at our factory.
Do we need to have a CoC after lights were replaced? We replaced fittings only in an existing installation.
Office lights are a plug-in system, 5 Amp sockets.

Where in the SANS 10142 do I find what is exempt from CoC?
