Hi,

The electricion already installed 100A, 3p breaker in Siemens panel and fed the elevator motor through a 100A+(3) 90A-fuses disconnect switch.
Now, Elevator company want us to install 175 A, 3p breaker with shunt trip,

Should we install a 200A-buss Square -D panel with provision of 175A shut-trip brker
adjacent to the existing panel and re-direct the elevator circuit in to this new panel......????????

Thank you

Note that,
I think Siemens does not have 175A breaker w/shunt trip

yes, replace fused switch with enclosed cb
make sure conductor meets code
make sure cb can be locked for use as a disconnect
