Core TradesQuestion 79 of 700
An electrical panel is being installed. Regarding circuit identification, the code requires that:
a.Only the main breaker be labeled
b.Each circuit be legibly identified as to its purpose or use
c.Labels be optional if the electrician remembers the layout
d.Only 240-volt circuits be identified
Explanation
Every circuit and circuit modification must be legibly and durably marked at the panel to identify its purpose, so anyone can safely identify and de-energize circuits later. Labeling only the main or only certain circuits, or relying on memory, does not meet the identification requirement.
