The Amperage Matrix
An assessment ensures your main supply can handle the specific draw of your unit compared to standard appliances:
| Unit Type | Peak Load | Amp Draw | Infrastructure |
|---|---|---|---|
| Standard Geyser | 3.0 kW | ±13.6A | 2.5mm² / 20A |
| 5.5kW Series | 5.5 kW | ±23.9A | 4.0mm² / 32A |
| 8.0kW Series | 8.0 kW | ±34.8A | 6.0mm² / 40A |
| NX13 Series | 13.0 kW | ±56.5A | 10mm² / 63A |
Why distance matters
If your unit is more than 10m from the DB board, voltage drop occurs. Our assessment calculates if you need to jump from 6mm² to 10mm² cabling for the NX13.
