I have to replace an existing unit substation that supports a 50,000 sf building. During construction, I am proposing a temporary roll up generator with a termination cabinet between the generator and existing dist. equipment to provide temporary electrical services during construction. The generator will feed a 800A MCB dist. panel. I understand per Art 590 (2011) a temporary service must be installed as a permanent installation er Art 230.

Are there any concerns that I should be aware of? I feel like I am missing something?

Thanks in advance.
