Question:
Hello,
Are surge protective devices required on emergency panelboards in commercial office facilities? The equipment was installed in 1984 and it appears there was not a requirement for this at that time.

Hi Grant,
Thank you for the question. Section 700.8 requires emergency system panelboards and switchboards to have listed surge protective devices (SPDs) installed.
