You don't state a location so how is anyone to know what codes to apply?

Hire a consultant before your incompetence kills someone.

This is an older building? A newly built building? or one you plan to build?

Then use the Sri Lanka building codes.

How hard was that.

Sri Lanka codes are based on Singapore codes. Singapore is based on BS7671.

Sorry, £85+ P&P to non members of the IET (I forgot about my members discount) I would also recommend you get the on site guide a bargain at £27 +P&P.

You will also need BS-EN 62305 (lightning systems) £230+ P&P

To put this another way, by a copy of your local codes/regulations and read and understand them.

PLEASE!

It makes a big difference if the portal frames of your building are concrete or steel. Concrete, you bond to earth from the wall/roof sheeting and the sheeting needs to be tested and linked for earth continuity. Steel, you bond to earth from the base of each column and the sheeting fixings are usually sufficient to take care of any continuity issues. If the portal frames are steel read up on PME (Protective Multiple Earthing)

  • Protective Multiple Earthing is simply one method of providing a safety conductor for mains electrical supply services.
  • In the UK, new electrical installations must comply with British Standard 7671 and Part P of the Building Regulations; the latter might not be applicable in Sri Lanka.
  • The Eiffel Tower in Paris is its own lightning conductor.

UK supplies come under ESQCR-2002 (Electricity Safety, Quality and Continuity. Regulations) or BS 7430-2011COP.
Lightning systems BS-EN 62305

Neither BS7671 or part "P" building control have anything to do with electricity supply.
