What is the required distance for a disconnecting means to be located from water heaters rated over 300 VA?

The correct answer specifies that the disconnecting means must be located no less than 50 feet from water heaters rated over 300 VA. This requirement is rooted in safety protocols to prevent hazards associated with electrical equipment and water. By placing the disconnecting means at a safe distance, it minimizes the risk of electrical shock for anyone who might be working on or near the water heater, especially in the event of leaks or spills that can create hazardous conditions.

The 50-foot distance is based on electrical codes and manufacturer recommendations that take into account both accessibility for maintenance and emergency situations where immediate disconnection might be necessary. This distance ensures that the personnel can have access to the disconnecting means without being in immediate proximity to potential electrical issues related to the water heater. Adhering to this requirement is crucial for maintaining a safe working environment.
