Why is the TNC-S a problem mate, would you class this shop as a special location ? such as construction site.

Its a steel constructed building and portable so is classed as mobile so if you read the reg section 717 in bs7671, regulation 717.411.4 states the following:
"In the UK a TNCS system shall not be used to supply a mobile or transportable unit except: A) where the installation is continuously under the supervision of a skilled or instructed person and B) the suitability and effectiveness of the means of earthing has been confirmed before the connection is made". now in my eye its a gray area so and a little old dear selling carrots i wouldnt class as skilled , i may be thinking to hard on this one but you know me always go down the worst case route

I was wondering if it's got a perm supply from either a final circuit or a distribution circuit it may not be classed as mobile. Quite a lot of factories have these port-a-cabin offices, espicially in large loading areas and bays and becasue they are on a permanent supply they are classed as semi-permanent I suppose for a better word.
