I have an old style service panel - the ground wire (from a rod in the ground) and the neutral wire (leading in from the pole) are both bonded to the box. I want to install a sub-panel where I will be using a 120v and a 240v circuit. I am planning on running a 10/3 line with a ground wire to the sub-panel from the service panel.
I will be attaching the neutral wire to the neutral bar which is not bonded to the box and will be sinking an additional ground rod then attaching the ground wire to a ground bar which is bonded to the box. Where should I place the ground wire coming from the service panel, to the neutral bar or to the "new" ground bar?
Here's a shot of the subpanel (work in progress). 20 amp breaker on the left powers the A/C, 30 amp breaker on the right to power sauna and light. Main lines from service panel not installed yet. #6 ground wire connects to newly installed ground rod below the subpanel.
