Maintaining Minimum Clearance for Nonmetallic-Sheathed Cable (NMSC)
What is the minimum clearance required for Nonmetallic-Sheathed Cable (NMSC) from framing members like studs or rafters?
a) 25 mm
b) 32 mm
c) 300 mm
d) none of the above
Final answer: NMSC needs to maintain a minimum clearance of 32 mm from the edges of framing members like studs or rafters; otherwise, it requires mechanical protection.Answer:
The correct minimum clearance required for Nonmetallic-Sheathed Cable (NMSC) from framing members such as studs or rafters is 32 mm (1.25 inches).
Nonmetallic-Sheathed Cable (NMSC) must maintain a minimum clearance of 32 mm from the edges of framing members like studs or rafters to ensure safety and compliance with the National Electric Code (NEC).
When NMSC is pulled through holes in framing members, it is important to follow this guideline to prevent potential damage to the cable from nails or screws during construction or occupancy. If the clearance is less than 32 mm, mechanical protection must be installed to shield the cable effectively.
Adhering to this clearance requirement is crucial for ensuring the integrity of electrical installations and reducing the risk of accidents or hazards associated with improper spacing of NMSC from framing members.
