NEC Code section 300.25, General Requirements for Wiring Methods and Materials is new for the 2020 Code cycle. This section regulates wiring located in Vertical Exit Enclosures, also known as stair towers.The new 2020 code language in 300.25 expands the requirement to “wiring methods” which is much broader than just “conduits”. Below is a preview of the NEC ®. See the actual NEC ® text at NFPA.ORG for the complete code .Sizing of Junction and pull boxes according to NEC Section 314-28. Today, I will explain Electrical Boxes Volume and Fill Calculations as follows. Part (A), “Box Volume Calculations,” defines the volume of a wiring enclosure or box.370-23 (d) (2) Enclosures Fastened to Support Wires An enclosure may be fastened to a suspended (drop) ceiling support wire while meeting the requirements of Sections 300-11 (a) and 370-23 (d) (2).
