Properties with multiple points of supply
218 Properties with multiple points of supply
If a property has more than one point of supply or is intended to have more than one point of supply, a person must not install or alter an electrical installation at the property or a portion of an electrical installation at the property unless the installation or the installed or altered portion of the installation complies with this regulation.
Any submains or subcircuits connected to a point of supply must only be installed within the boundary of a zone established within the property and must only supply electricity within that zone.
Each zone established within a property must, wherever possible, follow easily recognisable property features and must not intermingle with or cross over other established zones.
A zone diagram must be placed in each main switchboard within the property that contains the following information—
a diagram showing the location and boundaries of each zone;
the location of each zone's point of supply and consumer mains;
the location of each zone's main switchboard;
the location of any submains or switchboards located within any zone.
Subject to subregulation (6), each main switchboard at the property must be clearly and permanently marked with the following words—
"Warning—not all wiring installed in these premises is controlled from this main switchboard".
Subregulation (5) does not apply if a main switchboard can remotely control every other main switchboard installed or connected to the property it is installed in.
Each switchboard installed or connected to the property that is not a main switchboard must be clearly and permanently marked with a label that clearly identifies the main switchboard it is connected to.
This regulation does not apply to a property that is only supplied electricity from one point of supply connected to a distribution network and one or more points of supply provided by consumer electricity generation systems located within the allotment.
For the purposes of this regulation, point of supply includes the point where a supplementary supply or alternative supply provided from another allotment crosses the boundary of the allotment it is supplying electricity to.
In this regulation, allotment means land which can be disposed of separately under section 8A of the Sale of Land Act 1962 without being subdivided.
