MIL-DTL-16036M(SH)
3.10.3 Cable connector sizes. On switchboards having an AC bus structure designed for short circuit currents
of 15,000 amperes or less, single-conductor insulated copper cable, size AWG 4, in accordance with NEMA HP 6,
Type SSB, 392 °F (200 °C), shall be used for connections to 100-ampere frame size Type AQB circuit breakers. On
switchboard buses having a total connected DC generator capacity of not more than 150 kilowatts at 120 volts,
similar cable connections shall be provided for 100-ampere frame circuit breakers.
3.10.4 Cable connector sizes for casualty power. Cable connecting a casualty power circuit breaker to the line-
side of an AC generator circuit breaker shall be size AWG 1/0, in accordance with NEMA HP 6, Type SSB, 392 °F
(200 °C). Casualty power terminal shall be enclosure type similar to that depicted by method 2D-3-2 in accordance
with MIL-STD-2003-2. Cable connecting the casualty power circuit breaker and the casualty power terminal shall
be size AWG 2 in accordance with NEMA HP 6, Type SSB, 392 °F (200 °C).
3.10.5 Bus bar sizes. Size of the bus bars shall be selected on a basis of the current carrying ratings shown in
table II. In no case shall the bus bar sizes be smaller for a given current than the corresponding sizes listed in table
II.
