3.6.20.1.4 Two-, three-, and four-conductor shielded twisted cables shall
be types 2SJ, 3SJ, and 4SJ in accordance with MIL-C-915/60 without the fillers.
Outer jacket shall be furnished for tye 4SJ but need not be marked. Types 2SJ
and 3SJ do not require an outer jacket.
3.6.20.1.5 For I.C. switchboard applications shielded cables having more
than three conductors shall not be used.
3.6.20.1.6 Solid wire and tubing can be used within panel mounted assemblies,
(that is, terminal to terminal).
3.6.20.2 Wire size. Minimum wire size shall be selected from the values
shown in table 111 in accordance with the requirements specified in 3.6.20.2.1
through 3.6.20.2.4 (load values in table III include inrush currents).
3.6.20.2.1 For supply circuits (including synchro excitation circuits),
the wiring from the input back terminals or connector contacts to the line
terminal of the fuseholder or circuit breaker shall be capable of carrying
the amperage of the root fuse or circuit breaker without overheating or
damaging its insulation and shall be not less than size 16 AWG.
3.6.20.2.2 For distribution circuits the wire size from the load terminal
of the fuse or circuit breaker to the output back terminals or connector
contacts shall be determined by the circuit load data.
3.6.20.2.3 Wire size from a switch supplying several individually fused
branch circuits need not be greater than that required to carry the rated
amperage of the switch even though the sum of the individual fuse ratings in
the several circuits is greater than the rating of the switch.
