    Was wondering if any one could help me with wiring of an earth referance board. Have got 6 erb in different rooms supplied with a 16mmearth daisy chained between them from main riser. Each room has general sockets and power in it. How do you wire these circuits that are between rooms to the separate erbs in there correct rooms.

    I think you will need to give a better explanation of what your doing. An ERB or earth reference bar is the central earthing point in medical locations.

    I understand the purpose of the erb. It's just on our drawings we have got let's say a cleaners socket circuit in 3 rooms with 3 separate erbs on the wall in each room so just wondering how you would wire the earth between the rooms.

    Have you read MEIGaN? Apologies if you know it! http://www.mhra.gov.uk/home/groups/comms-ic/documents/websiteresources/con2018069.pdf
    I cant remember if the cleaners sockets need to be bonded back to the ERB but all the sockets used for medical equipment will need a separate cpc back to the ERB as will the lighting. I find it a bit unusual that the cpc's are daisy chained between rooms & ERB's, normally each ERB would have its own cable back to the main earth or distribution point.

    I believe my site foreman has copy of the Meigan. We were also wondering about this as been trying to get information of folk on site has been difficult nobody wants to say what is the right thing to do. As why I have decided to join this forum in hope of some helpful information on it.
