Service Entrance Sizing

[mgardner]

How much spare capacity do you plan for when calculating the service entrance rating for residential buildings?

What about for commercial buildings?

 

[Chamuit]

Zero or less.

 

[George Stolz]

Depends on too many variables. Each situation is unique, IMO.

 

[LarryFine]

I agree with George.





Next?

I worked with a guy who always used to throw 50,000 va "future",,,,on all his plans for commercial buildings. I think (and thought), that it was stupid. The power company never did anything different than the immediate load. It ususally only drove up cost on our end, which is not always acceptable if you don't need it.
