The maximum distance allowed between the ESS disconnect and the ESS is 50 feet.

The maximum distance allowed between the ESS disconnect and the ESS is 50 feet.

• A. 5 feet
• B. 10 feet
• C. 100 feet
• D. 50 feet

Answer: (D)

The idea here is where the ESS disconnect must be located in relation to the energy storage system. Keeping the disconnect within a practical reach from the ESS is important so you can quickly de-energize the system for safety or maintenance, and to avoid long runs of wiring that add impedance and hazards. The maximum distance allowed is 50 feet, so the disconnect can be placed anywhere up to that distance. Shorter distances are still compliant, but 100 feet would exceed the limit and not meet the requirement.
