RCD Protection For Old Installations

Former Community Member
Former Community Member

Hey there, 

Would like to hear your thoughts on the case. 

If the installation from the 70s or 80s with old mem board has no rcd protection for neither sockets nor lights (with metal front plate switches, which are connected to CPC), taking into consideration that the installation was working cheerfully since the old days till today and all Zs values are within the range of the installed breakers and overall good condition. Would this require an upgrade to rcd protection as of the 18th edition or would class as C3 as of best practice guide 4 suggest on eicr? 

How would you approach the situation?

Regards, 

Karolis

    There are no set rules, so you have to make a decision and be able to justify your reasons for coding it as you did.

    So, is it a house with a garden and driveway where people may be using electrical gardening tools and equipment or washing a car with an electric pressure washer?

    Is it a flat without access to any outdoor areas?

     

     

    Karolis what experience do you already have of carrying out EICR's? Have you just done a handful, hundreds or thousands? have these been in residential premises, landlord premises, commercial, industrial etc? Have you attended any formal inspection and testing courses?

    So forget you are doing for now this EICR on this landlords property. And you were inspecting an commercial or industrial property with the exact same age of installation, method of installation and protection methods, how would you code that installation?

    More of a handful,  I do not practice now full time as an electrician anymore, so doing just some odd jobs when requested. I`ve done mostly domestic, a few landlord, and a couple of commercials, but mostly new or with rcd protection installations. This is the first one where the line is so thin to distinguish the best outcome. 

    Yes, I have 2391. 

    No commercial or industrial of the same age. 

    Domestic of the same age yes, but still it had RCD fitted, in a split board, with couple spare slots. The board in question does not have even one slot left.
