Past practices related to work on rectifiers without a LOTO in place must be reviewed to comply with present standards and regulations. The use of troubleshooting tests that avoid the live voltage testing of components is encouraged. The qualifications of personnel working on rectifiers must be established to ensure that regulations in each jurisdiction are being met. Rectifier manufacturers are encouraged to include provisions to lock out the circuit breaker and to protect any exposed electrical terminals from accidental contact by workers.
