CHAPTER 6 – ELECTRICAL INSTALLATION 100
6.9.3 Connecting the cables
Checking the cable insulation
• Measure the insulation of each cable before
connection and verify that the results are within
the specification of the cable manufacturer.
• Leave the cable conductors unconnected at
both ends until the commissioning engineer
has given permission.
Risk of flashover!
High voltages will be present in the terminal
compartment. High voltages can cause flashover
between conductors with different electric
potential, and between a conductor and earth.
Therefore, maintain a minimum clearance of 55 mm
between a conductor and the terminals of any
other conductor, and between a conductor and
earth.
