Generator

[angel at doral]

In article 700, it states that no overcurrent protection is required if generator is within 50' or line of sight. What about a commercial establishment when the utility power (main disconnect) is located inside the building or structure, is a main for the generator required?

angel, when I read this post

and than combine it with your other post

Can a service entrance rated transfer switch which has no overcurrent protection be installed directly after the meter can?

it tells me you are not installing an "Emergency" generator per article 700.

If this generator is going to run the entire service it must be an "Optional Standby" generator per Article 702.

If your planning to run both optional and emergency loads from this same generator you will need two distribution systems from that generator.

You need to keep the NEC definition of "Emergency" in mind, you don't want to call it 'emergency' if it is not.

Emergency systems are those systems legally required and classed as emergency by municipal, state, federal, or other codes, or by any governmental agency having jurisdiction. These systems are intended to automatically supply illumination, power, or both, to designated areas and equipment in the event of failure of the normal supply or in the event of accident to elements of a system intended to supply, distribute, and control power and illumination essential for safety to human life.
