generator neutrals

Generator xfer panel just thru wall from breaker box. Do I need to move any neutrals, or just land the gen neutral on breaker box neutral bar? Generator panel has a 60A feed from breaker panel and a 30A feed from gen set. Two breakers are mechanically interlocked.

It depending on what brand name transfer switch you have there run the model number to us one of us will double check the connection to verify the correct way to hook up.

Merci,Marc

This is a Murray outdoor panel with two circuit breakers interlocked with their interlock device. Individual parts not marketed as a transfer switch, but all the components required to do the job.
http://www.gen-tran.com/assets/pdfs/EncoreInstall.pdf gives a diagram that is similar in size to what I'd like to do. They only bring the neutral in from generator then it continues to breaker panel. There seems to be no need to bring neutrals from breaker box to xfer panel and then tie them back to it. I have, however seen it pictured both ways. MOVE HOT WIRES ONLY - Removing breakers from main to xfer, tie in both line feeds from gen and POCO, then bringing load wires back into main to splice to wires that feed those desired circuits. Neutrals and grounds stay where they were.

Your transfer panel has what is known as a solidly grounded neutral. The generator needs to have the neutral and equipment grounds isolated from each other. Follow the instructions for the transfer panel as to only moving the "hot" conductors from the service panel to the appropriate switches in the transfer panel.
