When did NEC 2014 Section 230.71(A) first came in NEC? I have very old switchgear and they cannot seem to install main breaker and wanted to know when this rule came so that they can grandfather already 7th spare service breaker in service switchboard that they are going to use to fed new loads without having to install main breaker

If you can show it was compliant when it was installed, you might be okay.

Or get (written) permission to use it from the inspecting entity.

There's another thread debating whether an unused seventh breaker must be removed.
