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.

    This is the old chestnut that gets roasted on the forum every so often.


    If a customer uses the services of a NICEIC registered contractor it seems reasonable that they will expect the electrical work to be carried out by a trained and competent electrician with appropriate qualifications for the level they are working at.


    At the very least they need to be able to assess the existing electrical fittings and circuit to ensure it is actually safe to work on and connect new equipment to, then be able to check their own work is satisfactory before restoring the electrical supply.
