Question 1: Pump ABC has been isolated at the Motor Control Center (MCC) and the circuit is locked out. Workers at Pump ABC tested the local on/off switch and the pump did not operate. Is this a satisfactory test prior to doing electrical and mechanical work on the pump? if not please explain why.
Question 2: If Pump ACB has been isolate at the Motor Control Center (MCC) and the circuit is locked out. Is it also necessary to lock out the local on/off switch where pump ABC is located? If so why?
Appreciate your assistance.
