[FONT="]All penetrations of a fire separation must be sealed by an approved sealant that has a fire-resistance rating of not less then the fire partition.[/FONT]
·[FONT="]Electrical wires and cables that are totally enclosed in a non-combustible raceway may penetrate the fire separation. AC90 metallic armored cable is a good selection in this case. [/FONT]
·[FONT="]Electrical wires and cables, or group of wires or cables, of at least FT4 rating may penetrate the fire separation providing the diameter of the wire, cable or groups of wire or cable is not more then 25 mm in diameter. [/FONT]
·[FONT="]Single-conductor metal sheathed cables with combustible jacketing of larger then 25 mm may penetrate the fire separation providing the cables are not grouped.[/FONT]
·[FONT="]Combustible outlet boxes are permitted in a fire separation as long the opening in the fire separation is less then is no larger then 0.016 m2. Back to back outlet boxes, on either side of a fire separation are not permitted and must be offset to ensure the integrity of the fire separation.[/FONT]
