Wire Power Supply to AC Supply 3

Wire a Power Supply to a Cord

These instructions follow on from instruction set – Wire Power Supply to AC Supply, if you haven’t already read them it’s recommended that you do so first before proceeding.

DO NOT HAVE YOUR ELECTRONICS, ROUTER OR OTHER DEVICES PLUGGED IN WHILE YOU WORK ON THEM!
Check that you can see all pronged plugs of your router, electronics and other devices, ensure they are not plugged in.

Best practice – hold the plugs of your devises in your hand and visually trace the cords back to the individual devices. This will confirm they are not plugged in.

STEP 03

Preparing the Power Cord

What wiring colour code is used in your country?
Supply voltages vary from country to country and so do the wiring colours. You’ll need to find out what colours are used for single phase power cables. You’re interested in finding the colours for:

  1. Live,
  2. Neutral, and
  3. Ground

The following chart  will give you some examples but doesn’t necessarily correspond to your countries colours.

We’re going to connect  the cord to the AC terminals on the PSU so the female plug on the end of the cable is no longer required. Cut the plug off and discard, it will not be required or the rest of the installation.

Strip the outer sheath of the cord back about 30mm. Do not nick the individual wires as you may create a point where the wiring can short.

Then strip back the individual wires around 6-8mm each. Give each wire a twist and make sure there are no loose strands sticking out.

This is optional but recommended. Place fork terminals on the stripped wires and crimp the fork terminals with an appropriate tool. Test by giving them a tug to see if they come away, if a fork terminal does come away, dispose of it and start again. If you have the capacity to solder them on then that should be your preferred option.
