5.4.6 Additional circuits
They must be separate and protected from the main vehicle circuit with a suitable fuse.
The cables used must be of a suitable size for their use and must be well isolated. They must be properly protected in sheaths (not
in PVC) or in corrugated pipe ducting in the case of more functions (polyamide type 6 material is recommended for the corrugated
pipe) and they must be correctly installed,
away from impacts and heat sources . Take care to avoid any chaffing with other
components, particularly with live edges of the bodywork. When passing them through structural components (cross members,
profiles, etc.), suitable cable raceways or protection must be provided; they must be secured separately with isolating cable clips
(e.g. nylon) at appropriate intervals (approx. 200 mm). It is forbidden to drill holes in the chassis and/or bodywork for passing cables
through.
In the case of external panels use a suitable sealant on both the cable and on the panel, to avoid the risk of infiltration of water,
dust, or fumes.
Establish suitable distance between electrical wiring harnesses and other components as follows:
-
10 mm from static components;
- 50 mm from moving components (minimum distance = 20 mm);
- 150 mm from components that generate heat (e.g. engine exhaust).
Wherever possible it is good practice to follow a different cable route for signal cables interfering at high absorbed intensity (e.g.
electric motors, solenoid valves) and signals that are susceptible to low absorbed intensities such as sensors, maintaining in any event
a position as close as possible to the metal structure of the vehicle in both cases.
The plug connections and terminals must be protected and weather resistant, by using the same type of component as that originally
used on the vehicle.
Use cables and fuses with the characteristics shown in the following table in accordance with the current draw:

For uses of more than 30 seconds.
2)
Depending on the position and hence the temperature that may be reached in the housing, choose fuses that can be loaded to up to 70% - 80% of their maximum
capacity.
!
The fuse must be connected as close as possible to the current take-off point.
