Chapter 5 Connect Power Cables
Figure 50 Sample power cabling scheme with 230V power, 20A PDU

Note: This image is for illustration purposes only. Your hardware component
might look different.
In the preceding example, the Slammer control unit (CU) 0, the three Bricks, and
the Pilot in the four-outlet bank require 2.55A, 1.18A, 1.18A, 1.18A, and 0.60A
respectively, or 6.69A total. This total load is below the 10A limit for a four-outlet
bank.
If we modify the example to use 1115V, the cable connection configuration
depends on which PDU you are using. The same two Slammer CUs and three
Bricks draw 4.82A, 2.12A, 2.12A, 2.12A, and 1.45A or 12.63A total. This total
load is acceptable for the Pulizzi TPC 2104 PDU because the amperage limit for
a four-outlet bank is 15A at 115V.
For both the TCP2105 PDU and TCP2104 PDU at 115V, the maximum for four
outlets is 10A for each of the quad outlets. There are three Bricks and one
Slammer connected to one quad in the preceding figure, so that the load is
10.53A. This load exceeds the 10A limit on the quad. Reposition one Brick load
