Working in Iraq at a Military Barracks where personal live and is considered a commercial project the voltage here is 400v phase-phase and 220volt phase -ground. All receptacles are 220v. Do you think we should install a GFI or a RCD at the outside ac unit for a convenience outlet. Does the NEC show that this should be done in this situation.
 
I think GFCI protection is a good thing ,... in general . I'm not sure this facility falls under the scope of the NEC .. 220v general purpose receptacles ?? not sure I've ever seen any in any dwellings ?
 
On its own rights, the NEC does not apply outside the US. If a foreign country were to adopt the NEC, then it would become the local law. But they may need to make some amendments, in order for some of the NEC provisions to make sense in their environment.

I am working on a project in that neck of the woods. The voltage system is 60 hertz, 380/220 volts. The NEC only requires GFCI protection for 120 volt receptacle outlets. But for this project, any place the NEC would require a GFCI for a 120 volt item, we are including GFCI protection in the design of the corresponding 220 volt item.

Charlie, let me rephase the question, that if you were in the US would you have to install the receptacle in an commericial application. I know you have to do so for a residential application. Also Charlie we work for the US Govt. and they want us to apply the NEC as much as possible. Also if you look at the IBC section K1201.1.1 Adoption. Electrical systems and equipment shall be designed and constructed in accordance with the International Residential Code or the NFPA 70 as applicable, except as otherwise provided in this code. Dont mean to make things diffulcult with my question but what i will do is listen to you guys advice and compare. Also if we install anything it will be a RCD for this application. Thanks for all your help.
 
For a non-dwelling unit, a receptacle outlet that is installed outdoors to serve as the required outlet for an A/C unit is, indeed, required to have GFCI protection. Reference 210.8(B)(5), 2005 NEC. The 2008 NEC changes this to require any outdoor receptacle outlet in a non-dwelling unit application to have GFCI protection.

As I said, the NEC only talks about 125 volt rated receptacle outlets. Yours are 220 volt. But I would treat the 220 volt system using the same rules.

To be fair with you I do understand that the NEC may not cover this situation however I am not sure if you are famuair with UK { British } regulation ?

If so please check with UK regulations type 16 { the type 17 is only came out recentally and AFAIK it only used in the UK area }

And Yes you will need RCD for the convence receptale near the A/C unit

Merci,Marc
 
Under the Brit regs, which is what I understand Iraq uses, all sockets outdoors, and sockets that could be reasonably used for an outdoor applications (ie by an exterior door or in a garage) must be RCD protected. There is no Brit equivalent to the requirment for a convenience outlet by the A/C, probably because when the Regs were last revised, there were no houses with A/C in the UK :)
