| Preparation of Australian Nylon Jacketed Cables for Installation of Primary Connectors |
| The objective is to strip back the nylon jacket and polythene insulation to end up with the cable as shown below, whereupon a 54Super connector may be applied. |
 |
| Amerace offers the following suggestions for cable preparation. Standard electrical tools such as knives, cutters and pliers may be used to successfully prepare this cable for connectors, if done carefully. But to improve speed and especially to achieve consistently good results, (i.e. no nicks in the insulation) more specialized tools can be useful.
The following suggestions are based on the use of an AMP 606700-1 tool which we have found satisfactory for the purpose. If you have suggestions for other tools or methods that you would like to share with other installers, we would be pleased to publish them if you contact us.

| 1. |
Set the tool so that it will cut the jacket without nicking the insulation, and cut at point B, the jacket. The nylon jacket from point B to point D can generally be pulled off cleanly in one piece.
|
| 2. |
Strip the insulation from the wire from point C to point D. To do this reset the tool and cut at point C, after which the insulation can generally be pulled off cleanly in one piece.
|
The cable is now ready to apply an Amerace® 54Super kit.

Note:
A review of the above instructions will show that the tool needs to be reset twice for each connection. For speedier installation it may be advisable to 'calibrate' the tool by determining the two settings, and marking them on the blade adjuster. Or two different tools could be used.

| Benefits |
There are three of the many benefits of Amerace 54Super kits which are of particular value for their use on the Australian nylon jacketed cable.
|
| 1. |
The 54Super kit has a long water seal area which can seal to both the jacket (A to B) and the insulation (B to C) 'like a (long and tight) rubber band', so that any water that enters the kit between the jacket and the insulation cannot go any further, and is not a risk to the transformer.
 |
| 2. |
The seal area of the kit also includes ridges that act as o-rings to fill any die draw marks that may exist on the surface of the polythene insulation.
 |
| 3. |
The Positive Grip metal-to-metal lock of the housing to the pin or socket ensures a permanent mechanical connection. There is no risk of the connector sliding on the slippery polythene insulation.
