The minimum conductor size for intermediate or candelabra-base lampholders that are not part of listed decorative lighting assemblies is established to ensure safety and compliance with electrical codes. In this context, using an 18 AWG conductor size is determined to be sufficient for the typical current carrying requirements of these lampholders, while also considering factors such as heat dissipation and voltage drop.

The choice of 18 AWG reflects the balance between managing the load and maintaining safety standards, ensuring that the conductor can effectively carry the electrical load without overheating. This size is commonly used for low-voltage applications and is appropriate for the lower currents associated with these types of lampholders.

Using a conductor that is too small could lead to overheating and potentially create a fire hazard, while a conductor that is excessively large might be unnecessary and impractical for the application. Therefore, 18 AWG is the minimum appropriate size for these types of lampholders.
