Water heaters rated over what VA shall have a disconnecting means located within 50 feet and within sight?

The requirement for water heaters to have a disconnecting means located within 50 feet and within sight relates specifically to safety and accessibility considerations in electrical installations. Water heaters that are rated over 300 VA are recognized as needing this level of accessibility for several key reasons.

When a water heater exceeds this rating, it indicates a significant power draw that, in the event of an emergency or maintenance need, could pose risks if the disconnect is not easily accessible. The installation of a disconnecting means ensures that an individual can quickly cut power to the unit without having to navigate through various areas or access other equipment that might not be safely approached when a malfunction occurs.

By having the disconnect in sight and within a defined distance, it guarantees that individuals working on or near the water heater can quickly and safely turn off the electrical supply, minimizing the risk of shock or fire hazards. Such regulations are crucial for maintaining a safe working environment in residential and commercial settings, ensuring compliance with safety codes during installation and later during routine maintenance or emergencies.

In summary, units rated over 300 VA are specified in electrical codes to enhance safety protocols, thus the answer pointing to that rating is indeed the correct criterion for requiring a disconnecting means in close proximity.
