Wiring
Wire Sizing
- For complete connector body sealing the
ignition wire should be 16ga minimum and
the power and ground wires should be 12ga
minimum
Recommended Wiring Practices
- Wiring or electrical harness must not rub on
sharp edges.
- The electrical harness should not be
stressed at connections (see Figure below)
-
- The voltage drop between the battery and
the fan should not exceed 5% of the rated
battery voltage. This should be verified at
the pump’s maximum current draw.
Wiring or electrical harness must not rub or
make contact with a hot surface. There
should be 5" minimum clearance from the
exhaust.
- Wiring or electrical harness should be
supported at least every 18" to 20".
- To avoid possible fire or shock, do not pinch
any wiring or electrical harnesses.
-
- Incorporate Drip Loops into wiring designs
(see Figure below). The pump connectors
are environmentally sealed. However, good
wire management can help ensure a good
seal over the life of the product
- The use of Dielectric Grease such as Dow
Corning DC-4 is acceptable as long as the
connection is mated directly after grease
application to prevent dirt from being
captured by the grease
Wires pulling on connectors can
compromise the connector body seal
and possibly create a water intrusion
Wire routing provides a path for water to flow
down into connector
Drip loop collects water and sheds it away
from connectors
