|Electrical Systems - Maintenance and Testing|
Hospital-grade receptacles at patient bed locations and where deep sedation or general anesthesia is administered, are tested after initial installation, replacement or servicing. Additional testing is performed at intervals defined by documented performance data. Receptacles not listed as hospital-grade at these locations are tested at intervals not exceeding 12 months. Line isolation monitors (LIM), if installed, are tested at intervals of less than or equal to 1 month by actuating the LIM test switch per 18.104.22.168.3.6, which activates both visual and audible alarm. For, LIM circuits with automated self-testing, this manual test is performed at intervals less than or equal to 12 months. LIM circuits are tested per 22.214.171.124.2 after any repair or renovation to the electric distribution system.
