The above table is based on the following:
1) Use of Carling (C Series) breakers or CBI (D Frame) breakers. Breakers in these
series are equivalent in fit, form, and function and can be used interchangeably
within the same system.
2) The DPP2U panel is rated for continuous operation at a maximum input of 450A
per side @ 35C max., 400A per side @ 40C max., 320A per side @ 50C max.,
and 200A per side @ 70C max.

Connecting or disconnecting load circuits.
In cases where a breaker has been
installed follow the instructions in section 9.4 to connect the new output wiring.
Ensure that the breaker is in the OFF position until all connections have been made
and thoroughly checked.
Remember that if any 125A, 150A or 200A breakers have been fitted these will
require that the supplied link bar is fitted across the associated output bus bars.
Note that if power remains applied to the panel during breaker installation the
alarm LED will show red and the alarm relay will be activated until the new
cables have been connected and the breaker set to the ON position.
