This example shows how to use two split core CTs to monitor an entire service panel. This setup uses two ECM-1240 channels (CH1 & CH2), which allows viewing the consumption of each "Line" individually. The downfall to this is that two channels are required instead of one. This installation applies to 60A to 400A panels using the appropriate SPLIT-60, SPLIT-100, SPLIT-200 or SPLIT-400 CTs.

This example shows how to use two split core CTs to monitor an entire service panel. This setup uses only CH1 or CH2 of the ECM-1240. This installation applies to 60A to 400A panels using the appropriate SPLIT-60, SPLIT-100, SPLIT-200 or SPLIT-400 CTs.

Occasionaly a 400A service will consist of two individual 200A panels. As shown in this example, each 200A panel may be monitored seperately using CH1 and CH2.

Some electrical systems may have three electrical panels. Such could be the case of a 600A service using three 200A panels. Such an installation should make use of two ECM-1240 Devices.

Sometimes the power feed to the service panel has two conductors for each, Line1 and Line2. In this case it would require a substantially large, cumbersome and expensive CT to be able to snap around the conductor pair. The resolution in this case is to use two CTs for each line. The CT amperage in this case can be 1/2 that of the panel amperage. For example, four SPLIT-100 CTs would be used to meter a 200A panel.

There are circumstances where space restrictions prevents the use of split-core CTs. The picture in this example is an example of this. This case required the installation of four Micro-100 CTs to perform the job.

Notice that 100A CTs may be used for this 200A panel since each 200A Line is shared by two conductors/CTs.
