Here's a situation that I haven't run into before.

We are troubleshooting exit lights and emegency lights in an older school of 3 buildings. All 3 buildings have the same 227v volt 20 amp circuit for Exits & Emegergency lighting. The actual Classroom and Administration building is where the power source originated from and it continues into the two unattached gyms that are only connected to the main bldg. via a covered walkway. Conduit and circuit are run underneath these walkways; or in some cases on top; to the gyms.

The Main bldg. has it's own Service Feeder and Distribution and the Gyms also have their own separate Service Feeder & distribution.

There is not an Emergency Stand-by system in place anywhere on this property.

My question is - Is there a NEC restriction to having the same continuos ciruit and raceway feeding from the Main Building to the two Gyms? If there is; I haven't been able to find it in the 700 Articles.

A little help here would greatly appreciated!
