BS 7671:2008 Amendment 3 is coming, and there are a number of proposed changes. Take a look at the Draft for Public Comment, which is now available, so as to be able to provide your views. There is still time… By James Hunt:
Rob has asked this question about test equipment requiring 100mA trip protection and what is necessary to conform with BS7671:2008 (2011). His question has been answered by Eaton (Theme – Regulations and Legislation):
Safety and performance are two most critical requirements
for every electrical system. The quality of insulation, properly
working grounding system and active protection are to
assure safety of people, electrical systems and buildings
against electrocution, fire, and other equipment damage.
Robin-Amprobe KTS1625 tester verifies the safety ...
Robin-Amprobe Ground Resistance Testers are designed
to measure resistance of the grounding systems to verify
that the system has low enough resistance to provide
protection for people, equipment and structures.
A properly functioning grounding system is a critical safety
feature of an electrical system. It is used to mitigate the risk
The Robin-Amprobe Insulation-Continuity Tester is designed
to diagnose and prevent the breakdown of the insulation in
various parts of the electrical system such as wires, transformers
and motors. The KMP7036 features three testing voltages
covering wide range of commercial and residential applications.
The quality of insulation is critica...
Loop testing is a quick, convenient, and highly specific method
of evaluating an electrical circuit for its ability to engage
protective devices (circuit breakers, fuses, RCD’s). A “loop” is
defined by including unsuspected elements, where current has
found parallel paths to ground. A ground loop determines the
