PURPOSE:To accomplish the sharing with an induction type watthour meter without any transmitter, by mounting an auxiliary terminal block detachably at a position covering the front of a main terminal metal to allow the arranging of a main terminal metal block and an auxiliary terminal metal block in two layers longitudinally. CONSTITUTION:An opening 23 is formed on the front of a main terminal block 15 and an auxiliary terminal block 1 is mounted detachably at the opening 23. With such an arrangement, the front of a main terminal metal 16 is covered with the auxiliary terminal block 1 to allow the arranging of the main terminal metal 16 and an auxiliary terminal metal 3 in two layers longitudinally thereby securing mounting space for a number of auxiliary metals 3. On the other hand, the lengthwise dimension of the main terminal block 15 will be slightly longer than those in the past, which enables the sharing of the main terminal block 15 with a terminal panel of an induction type watthour meter without any transmitter. Moreover, the auxiliary terminal block 1 covers the main terminal metal 16 to contribute to the prevention of an electric shock.
