The following pre-connection and post-connection tests will need to be carried out before assets installed by an ICP can be adopted:
Pre-connection tests to be undertaken by both the ICP and UK Power Networks for Low Voltage Contestable Works:
Check that terminal equipment at all exit points is secure from public access, cut-out fuse carriers are in place with fuses removed.
Check that all cable routes are properly backfilled with no exposed cables.
Undertake insulation resistance test on assets to be connected.
Post-connection tests to be undertaken by UK Power Networks for Low Voltage Contestable Works:
Confirm voltage at each exit point.
Check polarity at each exit point.
Check Phase Rotation at each 3 phase exit point.
Check earth fault loop impedance within acceptable limits.
Seal cut-out fuse carriers with fuses removed.
Additional tests may be required as instructed by UK Power Networks.
