Single phase ampere meter connection | Amp meter Installation

Single Phase ampere meter connection:

This diagram shows how to make Single phase ampere meter connection. Amp meter Installation. In this circuit, we use a terminal block, SP MCB ( Single Pole Miniature Circuit Breaker ), and an Amper Meter. First, we need to connect the SP MCB with the phase connection, then connect the ampere meter with the phase connection. Then connect the neutral wire with the terminal block. Now this circuit is ready for use. If you want to know more about this circuit please check our youtube video below the post.

Components used to make the single phase ampere meter wiring:

01. Ampere Meter

Ampere Meter
Fig 2: Ampere Meter


The Ammeter (Abbreviation of Ampere Meter) is a Measuring Instrument used to find the Strength of the Current Flowing Around an Electrical Circuit when Connected in Series with the part of the Circuit Being Measured. For Direct Measurement, The Ammeter is Connected in Series With the Circuit in Which The Current is to be Measured. An Ammeter’s Current Sensitivity is Determined by the Amount of Electric Current Required by the coil of the Meter to Produce the Required FSD Movement of the Pointer.

02. SP MCB

MCB SP means single pole it protects only one phase switching. MCB (Miniature Circuit Breaker) Curswitch is the most basic general-purpose switch that you use to control a light or another device from one location. These Switches Have Two Brass-Colored Screw Terminals Connected to the hot Power Source Wires. (MCB) For any Distribution Board, the Protection System Must be Used in The Incomer. Phase and Neutral Single Phase Supply to break. 120-volt circuits, 15-20 amp single pole breaker is typically used.

03. Terminal Block

A Terminal Block Consists of Modular Housing With An Insulated Body That Secures Two Or More Wires Together. Terminal Blocks—Also Referred to as terminal Connectors, Connection Terminals, or Screw Terminals—are Used in a Wide Array of Applications Where Electrical Systems Need to be Safely Connected. Electrical Terminals are a Class of Electrical Connectors That are Used to Transfer Electrical Current From a Power or Grounding Source to use. Terminals "Terminate" by Crimping or Soldering to Wire or Cable.
