how do i determine the demand load of a building i.e. a school has a connected load of 299 amps what is the demand load? also does anyone know the maximum open circuit voltage on a dwelling unit? im using a study guide for the contractors exam and the approved reference materias do notseem to have this info in them.

See Section 220-34 and Table 220-34 and Section 210-6(a)in the 1999 NEC.
