Earth Continuity Test and Polarity Test following when replacing low voltage single phase fixed electrical equipment

Rob Bain
Hi all,

Would appreciate your thoughts on the need to undertake Earth Continuity tests and Polarity tests following replacement of single phase low voltage fixed electrical equipment such as tea boilers / heating pumps / immersion heaters etc, that are supplied either from a switched and/or fused connection unit or an isolator. The existing electrical supply cable is going to be re-used as the equipment being replaced will be like for like, so there is no increase in load, no requirement to undertake a design.

This enquiry has been put forward as it is anticipated that (some) engineers, who have a mechanical background but with limited electrical knowledge (safe isolation), would be able to carry out the replacement of certain items of plant once they have completed some competency training followed by assessment and sign off by the company's NIC EIC QS. 


Thanks in advance.

    It seemed an odd question on first reading it.


    A firm that is an NICEIC registered electrical contractor wants to get some of the non-electricians it employs to do minor electrical work, presumably for paying customers, on the basis that the QS and the firm will take responsibility for ensuring the work completed by these people who are not formally qualified as electricians is satisfactory.


    Then there is the question as to what testing should be carried out and certification produced.


    Both of these matters are something that should be asked of the QS, is the QS going to accept the responsibility of supervising these non-electricians when they are undertaking electrical work for customers and being qualified in design, erection and verification the QS should know the answer as to what testing and paperwork will be required for the company’s and customers records.


    So perhaps the question should be, what testing and certification to the firms electricians do when they undertake such work should be asked?


    Given the list of appliances given as an example perhaps it would be better to get the electricians to do the plumbing, rather than the plumbers do do the electrical work?
