Hey folks. I need some advice if I may?
I have a transformer (120VAC 60Hz primary, 28VAC secondary) which has a ground wire which is fastened to the outter casing of the transformer. Would this be a sufficient ground point for a power supply circuit using this transformer? basically, I would like to know if it is proper for the ground to be attached to this ground wire on the transformer, rather than grounding to the chassis.
Are there any drawbacks to using a ground point on the transformer casing?
Should I just ground to the chassis and remove the ground wire from the transformer casing?
Also, I'm using a mains plug that contains a ground wire. Should I attach this ground wire to the chassis, or should I attach to the transformer ground wire?
Also, should I install a diode to keep current from flowing back through the ground wire? (1N4001? 1N4148?)
Please see sketch. I thank you for your assistance with this.
