4.1 Scope and application
This section sets down the principles for the mechanical and electrical design of underground electric lines, other than those operating at voltages normally not exceeding 50 volts alternating current or 120 volts ripple-free direct current.
The requirements have been based on recognised industry standards.
They represent the minimum standards necessary to meet an electricity entity’s obligations.
Unless otherwise expressly stated, this section does not apply to:
- any underground earthing conductor not specifically associated with an underground electric line or with an underground control cable;
- underground electric lines or underground control cables fully or partly constructed in places owned only by an electricity entity and where a substation enclosure prevents unauthorised access;
- submarine cables; or
- fibre optic cables.
