Answer to Problem 1R

No, it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system.

Explanation of Solution

Description:

From NEC 220.60, it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system.

Conclusion:

No, it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system.

b.

To determine

Explain the reason why it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system.

Explanation of Solution

Description:

The National Electrical Code (NEC) is the basic standard code and it sets the standards for electrical installation work. The NEC safeguards the persons and property from hazards during the usage of electricity. The local and state electrical regulations and codes should also be considered along with the NEC for electrical installation work.

From NEC 220.60, the noncoincident loads such as electric heating and air-conditioner are not operated at the same time. Therefore, when calculating the feeder value that is used to supply both the loads, the larger value of loads can be considered.

Therefore, it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system.

Conclusion:

Thus, the reason why it is not necessary to add air-conditioner load and electric heating load to obtain the combined load on the system is explained.
