How to Connect a Relay Circuit: A Step-by-Step Guide

In my previous post, I connected an AC Relay, an AC Voltage Source, and a Heater plug. Here’s a simple explanation of how I did it.

First, prepare an extension cable.

Cut it in half. Mark two spots in the middle (where I’m holding with my left hand) to strip the white rubber insulation.

After stripping the insulation, you’ll see three wires:

• Live Wire (A/L) - Brown: Supplies power.

• Neutral Wire (N) - Blue: Completes the circuit by returning current.

• Earth Wire (E) - Green: Connects to the metal parts of the electrical device to prevent electric shock in case of a fault.

Cut the brown and green wires, but leave the blue wire intact.

Since the brown wire is cut, you now have two brown wires. Connect one to the A terminal and the other to the N terminal of the plug socket. Connect the green wire from the AC Source to the E terminal.

Now, the setup is complete.

One end is the power plug for the AC Source, and the other end is the wire. After stripping the wire, it will be connected to the Relay.
