Final answer:
To ensure the breaker can handle the load, it is important to round up the total load to the next standardized size breaker.
Step-by-step explanation:
Rounding Up to the Next Standardized Size Breaker:
When calculating the total load, it is important to round up the result to the next standardized size breaker.
This is done to ensure that the breaker can handle the load without any issues or inefficiencies.
For example, if the total load is calculated to be 1,600 Watts, it should be rounded up to the next standardized size breaker, which is 1,920 Watts.
This practice is necessary because there are safety regulations in place that limit the continuous usage of a breaker to 80% of its capacity.
So, even though the load may be slightly below the current capacity of a breaker, rounding up ensures that it stays within the safety limits.
