On the electrical plan, locate circuit tag C39; then read the panel schedule. What breaker is shown?

Correct Answer

D) 40A

Sheet E-837 shows C39 on the plan excerpt; the matching schedule row lists 40A in the Breaker column.

Answer Options
A
30A
B
60A
C
20A
D
40A

Why This Is the Correct Answer

Sheet E-837 shows C39 on the plan excerpt; the matching schedule row lists 40A in the Breaker column.

Why the Other Options Are Wrong

Option A: 30A

30A is the breaker entry for C38, not for the mark located on the plan.

Option B: 60A

60A is the breaker entry for C40, not for the mark located on the plan.

Option C: 20A

20A is the breaker entry for C41, not for the mark located on the plan.

Memory Technique

Two-step read for electrical and panel 38: find C39 in the drawing, then stay on that row until Breaker.

Reference Hint

Open Sheet E-837; locate C39 in the plan excerpt before reading the schedule row.
