Capacity check

You can request a capacity check to verify what phase and fuse size a property has, or to see if there is spare capacity for another connection. You can also ask for a load check at a transformer to see whether it has spare capacity for a new connection or upgrade. 

Our process



Call 0508 832 867 to request a capacity check


For verification of existing phase and fuse size we aim to notify you within 2 working days. For spare capacity checks we put a data logger on our network to monitor the usage.


We email you the results of the capacity check after data logging is completed, usually within 6 weeks.



FAQs

During normal energy use, the power supplied by your meter (9.2 kVA on average) should suffice.  In theory, this allows you to simultaneously supply devices with a maximum power of 9.2 kW or 9200 watts.  As you do not usually use all your electrical appliances at once, your basic installation should, in practice, suffice.

If you have special installations that consume a lot of energy, such as a sauna, pottery kiln or electric car, then that power might not be sufficient, and you may have to request an electricity upgrade with Vector.
