Standard lampholders with a rating less than what wattage should not be used for a low voltage configuration?

In low voltage configurations, standard lampholders should not be used for wattages exceeding 660 W due to safety and performance concerns.

Using lampholders rated for lower wattages, such as those less than 660 W, may lead to overheating, risk of fire, and potential equipment failure when in a configuration that requires higher wattage handling. This specific limitation ensures that the lampholders can manage the thermal and electrical load without compromising safety standards. The 660 W rating is crucial as it aligns with the maximum specifications that ensure reliable operation under low voltage conditions.

Adhering to this standard helps prevent electrical hazards and ensures that the system remains within safe operational limits. Thus, choosing lampholders rated for 660 W or higher is essential when designing or working with low voltage communication systems.
