How many loads can I monitor with an ECM-1240?

Although the ECM-1240 is a seven channel device, more than seven channels are typically monitored. This usually requires the addition of extra current sensors (CT) than what is included in a basic package.It is not uncommon to group several loads on to a single channel. This conserves the channel resources. Some typical examples would be to group the kitchen counter receptacles together, bedroom circuits together, etc. You can also group seasonal loads together such as “Heating” and “Air Conditioning”, since only one of the two loads would be operational at a time (I would hope.). Our “CT Selection” page provides some examples.
