Question:
Hello Code Question of the Day.
The question today is does the service disconnect have to be marked "Main" or "Service Disconnect"? The stickers that come with the panelboard say "Main." Can you provide clarification?
Thanks.

A
Answer:
Peter,
Yes, we are aware of this causing some issues in the field. Most people know what the term "main" implies, but The safe approach is to permanently mark the equipment and identify it as a "Service Disconnect" As clearly indicated in Section 230.70(B).
