Isloation of H.V motor and equipment
Isloation of H.V motor and equipment
(OP)
Is there a ruling or something that states you must isloate the power side of the motor to be able to inspect the machanical equipment. We have a SAG mill which at the moment they only lock out the control side to inspect inside the mill. we only lock out the H.V when work on the motor itself is required.

you gonna have to tell every body where you are. The rules in Australia are a lot different from say US then say Europe.
It's a simple principle where your butt is concerned. If it can go wrong it will. If my crew provide control cct isolation only for a mechanical job and it went wrong I'll have lot of talking to do with the police, dept. of labour and the electrical inspectors
This was discussed in a thread on stop start stations a little while ago and huge number of possible scenerios were posted as too how the motor or drive could start even with a tagged out (locked out) stop switch.
Isolte the power source if people are involved is my earnest advice. (that includes say air, hydraulic power and a lot of processes)
