Question:
Good Afternoon.
Does 2014 NEC require SPDs other than on Emergency Switchboards and Panelboards?
Kenny Scott
A
Answer:
Hello Kenny,
Thanks for the question. A review of requirements for surge protection in the 2014 NEC reveals that it is required in Sections 694.7(D), 700.8 and 708.20(D). Although the terms surge protection and surge protective devices appear more times than 3 in the 2014 NEC, those instances related to if surge protection is installed, triggering certain rules that must be met. Hope this is useful.
