QUESTION 19b:
HOW IS THIS TEST DONE AND WHAT VALUE OF MEASUREMENT IS ACCEPTABLE?
ANSWER:
a) Test that the polarity on all switches, sockets, appliance terminals and points of
consumption are correct.
b) Insert the TEL1TLB into all sockets, switch on and confirm polarity. Adaptors
could be used when terminals are open.
c) The correct wiring will be indicated by 3 lights. All must be on for correct status.
d) If any of the lights remain off, the table on the instrument will indicate the fault
condition.
e) To test at a light switch, remove the cover, confirm visually that the phase
conductor (Red) has been used. A non-contact voltage detector can be used to
verify polarity as this will only function with the magnetic field of a live / phase
conductor.
f) A phase rotation test must also be carried out if it is a 3 phase installation.
This is not applicable on a single phase. Results should then also be recorded
on the front of the certificate of compliance / test report (page 282 of
SANS 10142-1:2003) as illustrated in Addendum B – Pg 9.
g) The results can only be correct, if a fault is detected it must be rectified
immediately.
QUESTION 20a:
WHAT INSTRUMENT CAN BE USED TO TEST ALL THE SWITCHING DEVICES AND MAKE
AND BREAK CIRCUITS?
ANSWER:
Any tester similar to:
a) Toptronic TBM811
b) Toptronic T1132
c) Toptronic T1151
QUESTION 20b:
HOW IS THIS TEST DONE AND WHAT VALUE OF MEASUREMENT IS ACCEPTABLE?
ANSWER:
a) All switching devices for example light switches, circuit breakers, isolators, etc
should be tested.
b) Switches must be switched on and off. The circuit must be interrupted as intended.
c) Any defect must be rectified before the results can be recorded on the certificate
of compliance / test report.
d) The answer can only be correct.
QUESTION 21:
WHY SHOULD ANYONE BOTHER WITH THESE TESTS WHEN VALUES CAN JUST BE
FILLED IN ON THE FORMS?
ANSWER:
You are an ACCREDITED PERSON and have clear responsibilities spelt out by the law.
Furthermore, the law provides stiff penalties for failure to comply with the
requirements of the regulations, and / or for contravention of the law. These include
fines and / or imprisonment.
DO THE TEST CORRECTLY, HOLD YOUR HEAD HIGH,
AND BE PROUD OF YOUR WORK
