Hello all,
MIL-STD-461 has a requirement for any conductors in a cable assembly carrying "primary power" i.e. AC power from a vessel distribution bus to be separated out from the main cable bunch and routed separately in a test setup (clause 4.3.8.6). It also states that the primary power cables shall not be shielded. I understand the rationale for this, the explanatory notes at the end of the standard are most helpful. My interpretation is that: a. this only applies to AC power buses (like those referenced in MIL-STD-1399 <http://everyspec.com/MIL-STD/MIL-STD-1300-1399/MIL-STD-1399-300B_13192/> ) and not to DC power supplied from another part of the EUT or from some Associated Equipment b. power supplied in this fashion can be supplied within a shielded cable if that is what is specified in the final installation Having not done any MIL-STD work before I just wanted to make sure my interpretation was correct?
