Moving to Scotland

Moving to Scotland

Moving to Scotland

(OP)
I am a US PE electrical design engineer working for close to 15 yrs now designing buildings & tenant finish buildouts - primarily offices, hospitals, restaurants, etc.
I'm moving to Scotland next year and am not sure exactly what code they use. I have been told that the UK designs follow the IEC, but was also told that this applies primarily to the European continent only.
Can anyone steer me in the right direction on this?

RE: Moving to Scotland

Get a copy of BS7671: Requirements for Electrical Installations published by the IET. Make absolutely sure it is the 17th Edition.

The IET also publish a good little booklet called the On Site Guide which accompanies the regs, and seven (I think) technical notes. The OSG and the tech notes are being updated from the previous 16th Edition and the latest ones aren't out yet as far as I know. Even an older OSG could be useful until the update comes out because it is aimed primarily at domestic and light commercial installations, but don't pay full price for an older one.

RE: Moving to Scotland

Thanks - this helps greatly.  Is BS7671 adopted for the entire UK? And how often do new editions come out?

RE: Moving to Scotland

Yes, BS7671 is the standard for the UK. I don't know what applies in Northen Ireland and Eire.

The 16th Edition came out in the early or mid 1990's, and there were about three or four re-issues incorporating significant amendments between initial publication and the release of the new 17th Edition.

Something to be very aware of is that the UK changed the colours of the LV wiring to conform with those used in Europe. On a clean new-build it will not be a problem but when you have an older installation being amended it has some potential to confuse: black was historically designated as neutral and under the recent changes black is now designated as a phase colour; blue, previously a phase colour is now designated as neutral. No scope for confusion!

Another concept to come to terms with is the use a 'ring' as the final distribution circuit in domestic and light commercial installations. This will probably be quite unfamiliar if you are used to radial circuits. Not difficult, just different.

It might be worthwhile registering on an IET 17th Edition course:
http://www.theiet.org/events/courses/2008/17th-edition-3%20day-2.cfm
they hold them all over the UK at the moment so it would be a good idea to contact the course planners (at the bottom of this webpage) and ask for when the programme is to run again in 2009.
