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.

    Thanks, that's a good point. Like you say the polarity on a single phase supply (inadvertently swapping L and N) might not be so damaging but having the engineer sign to say he has tested the polarity (and earth continuity) would be belt and braces as well as providing some form of evidence that the installation was sound at the time of the work being undertaken.
