Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only

Domestic Installer - a scheme that covers general electrical installation work in UK domestic properties only.  But what if the dwelling has 3 phase due to size of house or for Solar PV or EV (Electric Vehicle or HP (Heat Pump)?


Eg 

Single phase safe isolation 3 point test at 230v AC nominal

3 phase 10 point test but at some point phase 1 to phase two at potentially 400v AC


As always please be polite and respectful in this purely academic debate.





Come on everybody let’s help inspire the future

  • It is important to note that a domestic installer is not an electrician. "

    which strikes me as an odd thing to say...

    The statement in the article is correct, providing you subscribe to the view that a qualified electrician must have a NVQL3 or equal. The domestic installer qualification is level 2. For contractors involved in a CPS, the EAS allows them to potentially move “employed” persons with such qualifications and sufficient experience into a lower risk category thereby lowering the amount of QS oversight required. The requirement remains, however, that the work of the “domestic installer” must be inspected and tested by an electrician. 

  • The requirement remains, however, that the work of the “domestic installer” must be inspected and tested by an electrician.

    I do not think that can be correct because a domestic installer is entitled to self-certify notifiable work.

  • Interesting observations, and quite an interesting extension from the UK govt. definitions here.

    NVQ level 2: competence,
    which involves the application of knowledge and skills in a 
    significant range of varied work activities, performed in a variety of contexts. Some of the activities are complex or non-routine, and there is some individual responsibility or autonomy. Collaboration with others, perhaps through membership of a work group or team, may often be a requirement.

    NVQ level 3: competence,
    which involves the application of knowledge and skills in a 
    broad range of varied work activities performed in a wide variety of contexts and most of which are complex and non-routine. There is considerable responsibility and autonomy, and control or guidance of others is often required.

    I fully support the idea of folk having to show appropriate competence before being let loose by the way. I'm just not sure how good a fit those two descriptions are to what we really need in the electrical game, as I think they are deliberately fuzzy to allow qualifications as diverse as hairdressing and estate management to use the same definitions, which is perhaps not so helpful. 
    I presume then that the likes of C & G decide in more detail what material corresponds to which level for any given topic. (as an aside I find the mis-use of the work "vocation" to be annoying, as I suspect very few people, except perhaps ministers of religion, and those with some mental disorder, are actually hearing voices - the 'voca' bit -calling them and telling them what to get qualified in.  I'm aware its the official phrase, it just grates.)

  • I find the mis-use of the work "vocation" to be annoying

    I know what you mean, but the OED has (dating from the 16th century) amongst other meanings: The means by which a person makes a living; a person's employment or main occupation, esp. regarded as requiring dedication. More generally: a trade or profession; an occupation.

  • To be clear, I was referring to the domestic installer qualification that Mapj linked in his post, not the domestic installer scheme.
