When used as grounding modules, they save
and reduce hardware installation on the air-
craft. Standardized modules are available with
wire end grommet seals for environmental ap-
plications and are track-mounted. Function
module blocks are used to provide an easily
wired package for environment-resistant
mounting of small resistors, diodes, filters, and
suppression networks. In-line terminal junc-
tions are sometimes used in lieu of a connector
when only a few wires are terminated and
when the ability to disconnect the wires is de-
sired. The in-line terminal junction is envi-
ronment-resistant. The terminal junction
splice is small and may be tied to the surface
of a wire bundle when approved by the OAM.
11-233. VOLTAGE AND CURRENT
RATING. Selected connectors must be rated
for continuous operation under the maximum
combination of ambient temperature and cir-
cuit current load. Hermetic connectors and
connectors used in circuit applications involv-
ing high-inrush currents should be derated. It
is good engineering practice to conduct pre-
liminary testing in any situation where the
connector is to operate with most or all of its
contacts at maximum rated current load. When
wiring is operating with a high conductor tem-
perature near its rated temperature, connector
contact sizes should be suitably rated for the
circuit load. This may require an increase in
wire size also. Voltage derating is required
when connectors are used at high altitude in
