Section 409.22(B) Documentation
(B) Documentation. If an industrial control panel is required to be marked with a short- circuit current rating in accordance with 409.110(4). The available short circuit current at the industrial control panel and the date the short circuit current calculation was performed shall be documented and made available to those authorized to inspect the installation.
Analysis of the Change
New section 409.22(B) was included to require a field marking requirement for industrial control panels to indicate the available short-circuit current at the industrial control panel and the date the short circuit calculation was performed. This information shall be documented and made available to the AHJ. This is similar to the available fault-current field marking requirements of 110.24(A).
