What is the minimum size of conductor required for signage?

1.5 sq mm
2.0 sq mm
3.0 sq mm
4.0 sq mm

The correct answer is: 2.0 sq mm

The minimum size of conductor required for signage is 2.0 sq mm. This size is specified in various electrical standards and regulations, which aim to ensure safety and efficacy in electrical installations for signs. Signage often operates under conditions where it is exposed to environmental factors, and using a conductor that meets the 2.0 sq mm requirement helps to ensure reliable operation while minimizing the risks of overheating and fire hazards. Additionally, a 2.0 sq mm conductor strikes a balance between mechanical strength and conductivity, making it suitable for the typical current loads associated with signage applications. Using a conductor that is too small can result in failure or inefficiency, while larger conductors may not be necessary and would increase costs without a significant benefit in most signage installations.
