Utility External Disconnect Switch Report

You are here


This report documents the safe operation of photovoltaic (PV) systems without a utility external disconnect switch (UEDS) in several large jurisdictions. It explains the rationale for eliminating UEDS.

Some states and utilities require installation of UEDS between PV power systems and the utility grid as a device to ensure line worker safety. However, eight states and many major utility companies have recognized that safety devices and features already part of all code-compliant PV systems make the UEDS redundant and have eliminated its requirement.
