Fire resistance of concrete for electrical conductors - NFPA

The 2017 edition of the National Electric Code (NEC) allows conductors to be installed under 2-inches of concrete to provide this thermal protection in several places including sections in Articles 230, 695, 700, and 708. This is intended to provide a 2-hour fire rating equivalent to loing the conductor outside of the building.

03/04/2022· Minimum dimensions and axis distances for beams made with reinforced concrete for fire resistance. 1 This table is taken from BS EN 1992-1-2 Tables 5.5 and 5.6. 2 The axis distance, asd, from the side of the beam to the corner bar should be a +10 mm except where bmm is greater than the values in columns C and F.

Calculated Fire Resistance | UpCodes

The minimum equivalent thicknesses of cast-in-place or precast concrete walls for fire-resistance ratings of 1 hour to 4 hours are shown in Table 722.2.1.1. For solid walls with flat vertical surfaces, the equivalent thickness is the same as the actual thickness. The values in Table 722.2.1.1 apply to plain, reinforced or prestressed concrete walls.
