Regarding power shutdown for maintenance
Thread Content
Power must be cut off for the maintenance of pump machinery to ensure safety. How does everyone cut off the power? Use the emergency stop button or completely cut off the power in the electrical room

Power is cut off during the maintenance of rotating equipment to prevent accidental startup of these devices while people are in contact with their rotating parts, which could result in injuries. To cut power from the switchboard, a sign must also be placed.
When the switchboard loses power, a sign must also be placed!
It not only needs to be marked but also locked, and whoever turns off the power must be the one to turn it back on
In the power distribution room, carried out by electrical personnel

We have had several accidents that cost lives; now it is stipulated that for systems with a power rating of 30 KW or less, the motor power cable must be removed, while for those with a higher rating, the cables connected to the contactor start button must be removed
Turn off the power, lock out the switch, and post a sign; it’s also safer to test it on the control panel.
