If using a crimp type connector,
remove cable insulation for 1/2 connector length plus an allowance* for
increases in connector length due to crimping. Insulation removal length shall not exceed 3 3/4" (95 mm) from
conductor end.
Do not install connector now
(Figure 8).
*Note: This assumes that the installer has determined the increased length of an aluminum connector crimped
with a specific tool and die.

Note: 1) Copper connectors do not require a length change allowance.
2) Maximum aluminum connector crimped length allowed is 7.50" (191 mm).
