Here you can find documents that give guidance on the wiring of meter stations for common situations. Please note this does not cover high voltage metering.
| Equipment | Length x Width x Depth (mm) |
|---|---|
| Single phase meter - short terminal cover | 170 x 120 x 120 |
| Single phase meter - long terminal cover | 220 x 120 x 120 |
| 3 phase whole current meter - short terminal cover | 170 x 170 x 65 |
| 3 phase whole current meter - long terminal cover | 245 x 170 x 65 |
| 3 phase CT meter - short terminal cover | 220 x 150 x 75 |
| 3 phase CT meter - long terminal cover | 260 x 150 x 75 |
| Ripple receiver (standard) | 175 x 110 x 75 |
| *Ripple control contractor | 160 x 75 x 65 |
| Esmart controller (owned by retailer): Refer to retailer for dimensions |
These diagrams apply only to Northpower-owned metering equipment (includes ripple receiver contactor).
Northpower will supply a controlled supply to a maximum rating 2A. If a load greater than 2A is controlled, e.g spa pool, the customer is required to fit an auxilary contactor.
Equipment and wiring must have adequate load and fault ratings.
The colours used in the diagrams are to distinguish between different phases, neutral and earthing conductors. The colour of the wiring should comply with AS/NZS 3000 rather than the diagrams.
Approval of non-standard arrangements should be referred to Northpower’s Network Planning Department.
These diagrams apply to new meter stations or meter stations that are being significantly upgraded (excluding meter replacement) Note: where a ripple receiver or contactor is replaced on a planned basis, an HRC or MCB should be installed, if there is none.
For controlled options refer to Northpower's tariff options.
CT: Current Transformer
HRC: High Rupture Current
