| **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.  | **DANGER:** Current transformers must be connected to a device, or short-circuited before power is applied in the circuit to be measured.
