A common cause of power quality issues in underground systems is the improper torquing of underground separable connectors. During the installation of these products, achieving proper connections is one of the most important yet overlooked step in the installation process.

1. Ensure cutback dimensions are accurate and all cuts are square.
2. Do not nick or cut the shield, insulation or conductor when preparing the cable. This can lead to over-heating and dielectric failure. 
3. Terminate the metallic shield as close to the separable connector as possible. Do not expose more of the semi-con than is recommended.
