Been asked to do an EICR on a large medical practice, now I'm ok with the actual I&T side of it but there are other issues bothering me, just wondering what your thoughts are. A few years back they rang up in a panic, it was midway through afternoon surgery, the place was full and they lost all power. There was no lighting, no computers,phones,power, absolutely nothing.
Fortunately for them I was in the supermarket around the corner so I was on scene in less than 5 minutes and within 10 minutes had power restored.The problem was water on an electric kettle base, this tripped the RCD, The problem was that the supply is 3 phase to a 12 way TPN board,with and RCD on the main incomer, there are no 3 phase loads and the board is fully populated,so that's 36 single phase circuits.
I was asked what could be done to prevent this happening again and as it's an obsolete board, my only solution was to replace it with a new one using RCBO'S. If I remember correctly I think I quoted £2000 for the work, it was deemed too costly! there are other issues involved here also, the vaccine fridges are fed from this board, the alarms on them are GSM based and whoever has set them up has used PAYG sim cards, again probably for cheapness, the problem is they are the type where if the credit isn't used by the end of the month it expires, as you can expect it's expired and not been replaced, so they have no alarms!
I'm worried about the consequences of doing the EICR on these premises, I know that when I list the issues on the cert, in particular the fact that the one RCD covering everything is a non compliance( there's no reason for this as it's a tns system) they will take no action regarding having the issue corrected, and while I don't think they'd have any legal come back on me if it all went wrong, it could damage my reputation. I just have this feeling that if there was an issue, they'd try and say I didn't warn them of the severity of the problem. My instinct tells me to beat a hasty retreat on this one, what's your opinion please.
