PROCEDURE FOR SHUTDOWN
Step 1 :
Before shutting down, thoroughly study the circuits and identify which circuit breakers or control switches wants to open. An alternative to the Consumer is to carefully study the supply mains, parallel feeders, duplicate busbar, etc.
Step 2 :
Keep the circuit breaker open and locked If you cannot lock the switch, remove the fuse and lock it and it should be kept secure. Locking the circuit breaker and keeping the fuses secure will eliminate the possibility that the supplier may return the wrong supply unknowingly while working on the line. Neutral links need to be disconnected. In the event of some fault, the potential of the neutral is increased, so the neutral link must be split.
Step 3 :
Hang the "Man - at - work" notice board on the circuit breaker or switch handle, This causes the supplier to fail to turn the ON while working .
Step 4 :
Test the supply after checking to see if the tools used to run it are working correctly. In case of an emergency shutdown, the wrong switch may be opened by inadvertence. These mistakes can cause serious dangers when someone lands the circuit or works on the circuit. The equipment used to measure the supply voltage must be made appropriate. The equipment used to test the supply must be in good working condition. Wear gloves for safety when testing the high tension line, You should also make sure that these rubber gloves are in good condition.
Step 5 :
Equipment is required to earth. Full security is guaranteed only if you shorten all lines and use proper earthing . The earth conductor must be of sufficient size to withstand the entire current when the fault occurs.
