Under the 2020 NEC 230.71, an inspector reviewing a new commercial service finds six circuit breakers used as the service disconnects in a single panelboard enclosure with no barriers. What is the correct inspection result?

Accept the installation because the historical six-disconnect rule still allows six breakers in one enclosure Reject the installation because 230.71(A) permits only one service disconnect unless the two-to-six disconnects comply with 230.71(B) separate-enclosure or compartment configurations Accept the installation if a plaque identifies all six breakers Reject the installation only if the combined rating exceeds 800 amperes

Correct Answer:

Reject the installation because 230.71(A) permits only one service disconnect unless the two-to-six disconnects comply with 230.71(B) separate-enclosure or compartment configurations
