Table 3-11. AC/DC Single Phase Output Connector Type
If two or more Sequoia/Tahoe chassis are used to form a single power system, the outputs of all chassis
need to be combined (paralleled by phase). This can be done directly at the EUT if convenient. Two blocks
are provided with multi-chassis systems, one 2-position block and one 3-position block. These blocks allow
up to four wires to be combined into one larger wire gauge size wire. The outputs of the 2 or 3
Sequoia/Tahoe chassis are connected on one side of these blocks (Phase A, B and C into the 3-position
terminal and the neutral into the 2-position terminal.). The EUT can be connected to the other side. Note
that the wire size to the EUT should be sized up to accommodate the double or triple currents per phase.
Note that even if the EUT is a three-phase delta input, the output neutrals of the Sequoia/Tahoe chassis
must be connected together for the system to work correctly.
