To determine the maximum recommended connected load for a residential branch circuit rated for 2,400VA, let's follow the general recommendation.
1. First, understand that the general recommendation allows for 70% of the circuit rating to be used as the maximum connected load. The circuit rating given is 2,400VA.
2. Calculate 70% of the circuit rating:
[tex]\[
\text{Max Connected Load} = 0.7 \times 2400 \text{VA}
\][/tex]
3. Performing the calculation:
[tex]\[
\text{Max Connected Load} = 1680 \text{VA}
\][/tex]
This step-by-step calculation shows that the maximum connected load should be 1,680 VA.
Now, let's look at the multiple-choice options provided:
- a. 1,680VA
- b. 1,920VA
- c. 2,040VA
- d. 2,160VA
Based on our calculation, the closest and correct choice is:
- a. 1,680VA
So, the answer is:
- a. 1,680VA
