14—Inspection and test results of earthing systems
The results of visual inspections and resistance readings must be recorded and audited to identify changes that would influence the frequency of inspections, tests and maintenance.
15—Inspection and testing of protection systems
	(1)	Protection systems must be inspected and tested from time to time as required according to the risk of damage to, or aging of, components or changes in the network electrical parameters, to ensure that—
	(a)	detection sensitivity; and
	(b)	speed of operation; and
	(c)	discrimination of load currents; and
	(d)	co‑ordination with other protection systems,
of the systems are being maintained.
