I'm doing some work on a 60Hz system on a US installation in Rota, Spain, and wanted to reference the local building and electrical codes. Normally in cases like this, we just do the installation IAW NEC 2005 as if we were stateside, since we're not exactly going to have local building inspectors coming on base, but I'd still like to cover ourselves legally, should something arise. And unfortunately, I don't speak spanish beyond "Dos cerveza, por favor". What relevant codes do Spain use?

We'll be doing mechanical work as well, with crane service, if you happen to know those codes too? Thanks!
