Figure H - Grounding Diagram
To ground the cabinet, see Figure H above.
1. Drive the ground rods into the ground near the cabinet location.
2. Use a Megger-type ohmmeter to measure the resistance between cabinet ground and the ground rod. The
resistance must be 25 ohms or less.
3. If the resistance requirement in Step 2 is met, proceed to step 4. Otherwise, follow local practices to lower
the resistance to ground.
4. Connect a #6 ground wire to the ground rod.
