Services, Grounding & BondingPregunta 35 de 120
What is the minimum size copper equipment grounding conductor for a circuit protected at 60 amperes?
a.10 AWG
b.12 AWG
c.8 AWG
d.6 AWG
Explicación
Table 250.122 is entered by the rating of the overcurrent device ahead of the circuit, and the 60-ampere row calls for 10 AWG copper. 12 AWG is listed for 20 amperes, 8 AWG for 100 amperes, and 6 AWG for 200 amperes, so all three are the wrong rows.
