A fifty-unit apartment building has a 4. 5-kw electric clothes dryer in each apartment. By using the optional method, what is the service demand load?

Respuesta :

The demand load is 58.5 kw.

Given 4.5kw electric cloth dryer.

Service demand load is to be computed.

The operational load (including any tactical load) and nonoperational demand loads are added together to form the demand load. It is calculated by adding the appropriate demand factor to each linked load and a diversity factor to the total.

According to the national electrical code, a building with 50  units the demand factor is  26%.

Now demand load = 4.5kw × 50 × 26%

                             =4.5kw×50 × 26/100

                             = 58.5 kw

Therefore, the demand load is 58.5kw
