    Low Voltage Connections

    For information on Guernsey Electricity's requirements for connection onto the low voltage electricity network, please see this guide.

What is additional load?

In Guernsey, properties receive electricity through an underground supply line cable that is connected to the wider electricity grid. Similar to a plug extension in your home, there is a finite supply of electricity ("capacity") available on the cable and more electrical installations demand more from the supply line cable. 

Nobody can tell just by looking at the ground how much capacity there might be to supply a property. This is why an ‘additional load application’ is sent by an installer to Guernsey Electricity each time electrical work is requested. This includes (but not limited to) electric heating upgrades, a car charging unit (above 3.6kW) or re-wiring for an extension. An engineer will need to establish how much capacity you currently have, and how much extra you will need to properly meet your needs. Nobody wants a heating system that only works when everyone else has got their appliances switched off.
