Different types of meters are used in the MCC panel for indicating the status of the panel.Mainly three types of meters are used. Ammeter, Volt meter, Watt meter, Energy meter. Analog and Digital type meters are using nowadays.

Ammeter

An instrument used for measuring the current flow in the circuit is called ammeter. It should be connected series to the circuit .
