By using a changeover switch to wire one motor with two meters, it is safe to choose which meter to monitor the motor. There is only a meter in operation at any given time, avoiding erroneous readings and back-feed, without affecting the normal operation of the motor.

Basic Formula:
Each switch controls its respective light:

3 Light and 3 Switches Wiring Diagram is a simple construct of electricity with three switches, each controlling one of the three light bulbs respectively. This kind of circuit is widely applied at both residential and schooling places and in small offices. All the switches are in series with the respective bulbs, thus they can be operated separately. It makes fault finding easy, saves energy and maintenance is easy. This arrangement operates on phase-live wires in which they do pass through the switches and common neutral line returns. It would be perfect in situations which individually require control of each light-like a bedroom, hallway or classroom. The guide contains a plain schematic, a table of the input-output connections, and a description of the basic wiring formula to assist an average DIYer and an electrician.

| Switch No | Input (Live) | Output (To Bulb) | Connected Bulb | Output (To Neutral) |
|---|---|---|---|---|
| S1 | 230V | 230V | Bulb 1 (L1) | 0V (Neutral) |
| S2 | 230V | 230V | Bulb 2 (L2) | 0V (Neutral) |
| S3 | 230V | 230V | Bulb 3 (L3) | 0V (Neutral) |
Frequently Asked Questions - One Motor Control With 2 Meter Connection Wiring:
Why connect a motor to 2 meters?
To monitor energy consumption or load from different sources or for multiple users.
How does the changeover switch work?
It selects which meter is connected to the motor supply at a time.
Is only one meter active at a time?
Yes, to prevent back-feed and ensure accurate readings.
Where is it installed?
Between main supply, meters, and motor input.
Are protective devices needed?
Yes, MCBs or fuses are required for safety.
Is earthing required?
Yes, to ensure safe motor operation.
How to test the wiring?
Switch between meters and verify motor runs normally and meters record correctly.
Can this setup be used for any motor?
Yes, if motor voltage and current match supply and meter ratings.
Does it affect motor operation?
No, motor runs normally regardless of which meter is selected.
Why label meters and switch positions?
To avoid mistakes and ensure correct meter selection.
