_________________________6. Separator and Spacer Type
This type of cable support has the codes that follow: ABS0054
ABS0731
E0688
NSA5527
R R R R R R You can use these types of cable supports to keep the electrical wiring separate. When their use is mandatory, they are shown in the installation drawing. If necessary, you can add spacers to get a correct clearance but you must keep them to a minimum.
R R This type of cable support is used in all areas except hot areas. In these areas, lacing tape NSA8420-2 is used as separator (noose type knot).
R ____NOTE : For EFCS harnesses, the use of spacers or separators is prohibited.

7. Specific cases R (Ref. Fig. 017)
In some cases (for example in VU, interface areas...) the structure (colonnette) or ramp is used to support the wiring to make sure that:
-it is not pinched during the VU installation in position in the aircraft, or
-rubbing does not occur during the life of the aircraft. To be approved, the structure or ramps which are metallic must have a protection of special paint (for the ramp) or a heat shrinkable sleeve (for the colonnette).

__________________________________CLAMPS - DESCRIPTION AND OPERATION
_______1. General
This chapter gives the description and operation for clamps. The clamps are
items used to attach the wiring.
A very wide range of clamps and mounts are used.
R The main clamps installed on aircraft have the codes that follow :
R - ABS1339 protected nylon clamp
R - NSA5515 non protected nylon clamp
- NSA5516 or MS21919 protected clamps
- NSA935807 "P" clamp for convoluted conduit.
