I am currently looking at TCUG guidance Note 1 which in section 2.4.7
suggests that core to core testing may be omitted as there is a
possibility of :-
1. Reduced safety for highway users whilst installation inoperative for
lengthy periods (perhaps up to 3 days at complex sites).
2. Insecure reconnection of cables especially on older installations.
3. Incorrect retermination of cables at either street equipment or
controller.
4. Additional traffic congestion while temporary arrangements in
operation.
5. Loss of special facilities (pedestrians, cycles, bus priority) for
long periods
Whilst I agree with this the document then recommends that the
continuity of the steel wire armour be tested. The test procedure for
this is to disconnect every core at the pole cap and then connect all
cores together and connect to the SWA.
Surely some of the arguments for core to core testing apply to this as
well.
Does anyone have advice on this and is there an alternative test that
could be carried out that would meet the requirements of BS7671 without
having to disconnect all connections in the pole cap.
