Reduced Voltage Starter removal
Reduced Voltage Starter removal
(OP)
Hello:
I am currently trying to write the "working instructions" to remove a reduced voltage starter circuit hooked up to a 100hp motor that activates a fan. The reduced voltage starter has a auto-transformer configuration. Wanted to know if there are any electricians/engineers that know, OR could point me to the direction of step-by-step instructions to remove such a circuit?? I am having a hard to writing down these instructions AND finding someone to assist. I am only focused on the reduced voltage starter circuit and thats it (just basic instructions). Anyone with this knowledge I would appreciate it. Thanks

Are you replacing the RVS with something? If it was needed that function is still needed.

If this were a Wye-Delta starter you may need to instruct the demo people to carefully mark the 6 cables going to the motor, that's important later, but an auto transformer will not have that issue.
If you were thinking of trying to maintain the integrity of the starter to re-use it, I'd say don't bother. That transformer is do big and heavy, the only way to effectively remove it will be by completely disconnecting all of the conductors and removing the contractors first. Besides, the starter as a unit isn't worth any heroic efforts to save it, other than as individual parts.

The supply circuit(s) should checked and verified that the correct circuit has been isolated. The mere absence of power does not guarantee that the proper circuit has been isolated. Not all plant or industry lock-out procedures recognize this point.
After isolation and verification, the circuits should be secured with locks.
After that, procedures will depend on the construction of the starter and the reason for removal.

Here:
1. Lock-out and tag-out the equipment.
2. Remove the cables tapped at the load side of the circuit breaker.
3. Remove the motor lines connected to the RV starter equipment.
4. Remove the RV starter from the cabinet.
5. Release yout LO/TO permit.
END OF JOB.
