 The appropriate size of motor contactors should be selected based on the load served and the genset size. The 400A frame is a good general purpose selection, but smaller or larger can substituted.

+**DANGER:** Current transformers must be connected to a device, or short-circuited before power is applied in the circuit to be measured. Current transformers are //constant current// devices, not //constant voltage// like ordinary transformers.
+  * **A C.T. with loose leads can have lethal voltage on the terminal, possibly over 1000V.**
+  * **Do not disconnect a C.T. when power is present in the measured circuit!**
