Cables
Where services are to be provided directly from a substation with Your cables laid direct into a trench, the trench should be excavated in a straight line from the substation to a position beneath the main circuit breaker, and designed/sized to:
suitably align with the location of the egress point of Your cables from the substation (egress point location to be agreed with UKPN).
ensure cable bending radii are accommodated – at and within the substation and below the main circuit breaker.
safely achieve the full cable rating.
