How is this rule interpreted in your area by electrical inspectors, or others involved in this type of work?

Are you required to submit a plan for the electrical installation, even for small jobs?

215.5 Diagrams of Feeders

If required by the authority having jurisdiction, a diagram showing feeder details shall be provided prior to the installation of the feeders. Such a diagram shall show the area in square feet of the building or other structure supplied by each feeder, the total calculated load before applying demand factors, the demand factors used, the calculated load after applying demand factors, and the size and type of conductors to be used.

This obviously does not apply to single family dwellings around here because I have never had to submit any info. The architects submit plans but often the electrical isn't even on the plan. Definitely no feeder plan or calculations being done.

Commercial-- it may be different--
 
Even a stand alone permit for a 200A service change requires a riser dia. with a load calc. We don't use CAD, just a sketch on printer paper with a hand written calc. (not very professional looking but they come back stamped)
 
Residential work around here doesn't usually require one if the service is 200 amps or less. Beyond that the POCO will want one to see if a larger than 200 amp service is really needed.
 
never even heard of such requirement on new or replace services. The POCO around here requires that anything new or replaced be 200 amp 2/0 period unless demands are more. Then they require you to submit plans. but only a calc load and would have to be a pretty big house.
 
NYS requires that a permitted job of a certain dollar value (I am not sure of the value...maybe $10,000) be submitted with an architects seal. They are supposed to include all the different mechanicals and electrical. Yet it is not equally enforced in most municipalities. Plan review for most municipalities does not include electrical.
 
It applies to all installations, if required by the AHJ. I only require for commercial jobs (other than tenant finishes), and also for large residential. I also ask for it if 230.90(A) Exception No. 3 is being used.

Really, this section isn't anything more than giving the AHJ the blanket right to ask for load calculations.
 
The Florida Statutes and Florida Administrative Code mandate this and other requirements for submittal documents that exceed the requirements of the NEC.

Always check your superseding laws and rules.
