 +**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!**
