Do I need to bond the neutral of a 208v to 120v control transformer. The panel that feeds the transformer has the ground and neutral bonded inside the panel. It is a 500va transformer.
Thanks
No, You can bond it or let it float at your option. I prefer to bond it...it makes voltage reading to ground more meaningful, makes troubleshooting easier.

Please consider grounding the 120V-secondary winding. For 1000VA-and-under control-power transformers, NEC 250-30 allows the winding to be grounded with a simple 'case' jumper. The usual full-tilt grounding-electrode/building-steel connection is not needed. This is a real easy way to keep electrostatically-induced garbage off the control circuit.

Thanks for the answers. It will be bonded tomorrow!
I second Bjarney's suggestion!
