In a load-arithmetic exercise, a garage circuit has a stated usable current budget of 15 A. Each simultaneously operating tool draws 4 A, and no other load operates. What is the greatest whole number of these tools within the stated budget? This is not a code rule limiting the number of installed receptacles.
- A1
- B2
- 3
- D4
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why C is correct
Three tools draw 12 A; four draw 16 A and exceed the stated 15 A budget. Receptacles themselves do not each draw 4 A. Real circuit design requires applicable load, protection and installation rules beyond this arithmetic.
