ESS disconnecting means shall be provided for all ungrounded conductors derived from an ESS and permitted to be integral to listed ESS equipment. The disconnecting means shall comply with all of the following:

• The disconnecting means shall be readily accessible.
• The disconnecting means shall be located within sight of the ESS. Where it is impractical to install the disconnecting means within sight of ESS, the disconnect shall be installed as close as practicable, and the location of the disconnecting means shall be field marked on or immediately adjacent to the ESS. The marking shall be of sufficient durability to withstand the environment involved and shall not be handwritten.
• The disconnect means shall be lockable open in accordance with 110.25
• For one-family and two-family dwellings, a disconnecting means or its remote control shall be located at a readily accessible location outside the building.
