Power testing is essential for both new and existing electrical installations. All power wiring and equipment will deteriorate with age and every electrical installation will require testing and examining at various stages through its life in order that the system is safe for continuing use. Even new pv panel should be thoroughly examined and inspected before being placed into service to ensure that they meet the current standards of the IEE wiring regulations and have not been sacrificed by human error or damage during construction work. metrotest.co.nz
The IEE electrical tests regulations can be found in BS7671, Chapter sixty one which includes details of tests which should be carried out to determine if the wiring system is acceptable to be used. Section 611 of this relates to new installations and provides a set of inspections that should be carried out before testing.
Determining the condition of a current electrical set up, the frequency of intermittent testing and the tracking of test the desired info is also an important part of an inspection and assessment agenda. These are protected in Chapters 62 and 63 of the polices and provide the requirements for detailed examination, verification and certification. Model forms for recording test results and inspections are located in Appendix six.
Electrical assessment involves an factor of risk and the IEE Regulations are the requirements for Health and Safety regarding Competent Persons very safe Isolation. Anyone carrying away inspection and testing has an obligation to ensure the safety of themselves and others.
The explanation of a Competent Person can be found in Part 2 of BS7671 and would be fairly need to meet all of the following requirements:
Possess enough experience and technical knowledge to avoid danger to themselves yet others by following Safe Remoteness and Testing Procedures
End up being skilled and familiar with the testing procedures and safe functioning of appropriate test instruments
Have an understanding of the current requirements of BS7671 relevant to the kind of installation for inspection and tests
End up being in possession of enough information about the set up to allow them to carry out the work safely. This would include being able to re-instate the installation in a totally safe and serviceable express after the inspection and testing is completed.
Tests and inspecting of electric powered circuits requires normally ‘live parts’ to be subjected by the inspector. Control 611 requires that tests and inspection procedures should be undertaken with the relevant circuits disconnected from the supply. Any work must be carried out for compliance with the Electricity at Work Restrictions which identifies the risks of any work or activity near ‘live’ conductors.
