Unmetered supply connections

Find out how to connect traffic lights, security cameras and other unmetered supply (UMS) devices to the electricity network for a reliable power supply. UMS connections don’t need an electricity meter because the electricity usage is predictable or can be accurately calculated without a meter.

Please note: The six UMS devices below are the most common, but there are many others such as boom gates, radio towers and town clocks. See our Approved UMS Devices List (PDF 185.0 kb) and UMS Devices Needing Assessment List (PDF 138.1 kb). The connection process is basically the same for all types of devices.
