NOTE:
If you are using aluminum wires you need to follow the following steps to prep
each cable prior to connecting to the AC terminal block:
a) Using a utility knife, gently strip the top layer of the aluminum conductors
Figure 2-38 Preparing aluminum wires prior to connecting
b) After removing the oxidized layer immediately apply neutral grease (Noalox or acid-
and alkali-free Vaseline) and connect the cable immediately to the terminal. Perform
one cable at a time. If you need to stop the process before applying the grease, and
continue later- you will need to scrape it again. It takes 30-60 seconds for an oxidized
layer to form on top of the conductors.
