6.3 Grounding the cabinets
When installing multiple cabinets in a row, daisy-chain the grounding cables as shown in Figure 6-2, and
connect the last grounding cable to ground via a ground bar.
Figure 6-2 Connecting cabinets to ground (multiple cabinets in a row)
Because each cabinet is grounded at a single point, the cabinet must be insulated from the base.
Figure 6-3 shows an example of insulating the base.
