Solid Core CTs up to 400 Amps is supplied with this meter. The LX 400 Amp CT works in a range of 4 to 400 Amp. The solid core CTs are more accurate than the split core and are much smaller. Split Cores are available if the power cannot be turned off. The (H1) or white dot, depending on the manufacture, faces the line side of the service.

In most cases, the control transformer is used to reduce the main or line voltage of 240 VAC or 480 VAC to a control voltage of 120 VAC. Notice that the primary windings are crossed. This is done so that metal links can be used to connect the primaries for either 240 or 480 VAC operation, as shown in Figure 1.10.
