SPD required after EICR?

Hi, after completing an EICR, should the lack of an SPD on a perfectly otherwise adequate board be classed as C2 or C3?

Also are SPD's required for any new circuit or only required when changing a fuseboard or for any circumstances where the SPD would be required to further protect any vulnerable equipment?

  • Hi Stuart

    It is also worth checking the smoke alarms, Carbon monoxide alarms and heat alarms when doing an EICR.  Functional test and the expiry date if they have one. 

    Aico do some good free CPD on this and also some paid for courses.

  • As an EICR is to see if the installation is safe or not i don't see as it should be coded at all generally. In the report summary i always put it is a recommendation but don't code it as i don't see it as unsafe.

  • or if wiring alterartion are done.

    Limiting to domestic ... perhaps a major one, but not, say, fitting a new inexpensive appliance in a dwelling (unless the manufacturer specifically requires SPD, or there is a risk to life or other mandatory requirement),

    Installing, a system, such as Solar PV, where the work is into £1,000s, is a different matter, and the relatively insignificant cost of an SPD

    In other premises, say with larger installations, even if there is a risk to life, more work may be required to determine the SPD system to install for the "one circuit".

    There really is no "clear and distinct, always works" answer to this question.

  • SPD cost might be £30 to £100

    Could be even more!

    If an SPD gets fitted then the customer needs to be made aware they are meant to periodically check the flag on the SPD to see if this is still in good order.

    Mine came with a switch which can be used to illuminate (or extinguish) a signal lamp.

    I suppose that yer average customer will check the flags every time when they press the RCCD test buttons. ;-)

    (It will be that time of the year this weekend. Not my idea, but JP's - do it when the clocks change.)

    A further consideration is the distance from the intake to the final DB(s). If it is too far (> 20 m) an SPD is required at the DB.
