How many circuits does the 42-Circuit Panelboard HB contain?

Explanation:
Circuit count is defined by the panelboard’s designation. A panelboard labeled as forty-two-circuit is designed to hold forty-two circuits. The HB part is just a series or enclosure identifier and doesn’t change that capacity. You might not use all spaces in a given installation, but the panel’s rating remains forty-two circuits.
