PURPOSE: A terminal block for CT/PT-operated meters capable of enabling comparative measurement is provided to compare the metered data of CT and PT operated meters with each other. CONSTITUTION: A terminal block for a CT/PT-operated meter capable of enabling comparative measurement is composed as follows. A voltage terminal is divided into first and second conductive terminals. The divided first and second terminals touch each other using three connection pieces(13). The connection pieces are simultaneously cut off or short-circuited. An auxiliary terminal block(12) is connected to the first terminal. A voltage-current grounding bar(16) is exposed to the outside a main body and is easily short-circuited.
